Vantage Titan 3T systems are indicated for use as a diagnostic imaging modality that produces cross-sectional transaxial, coronal, sagittal, and oblique images that display anatomic structures of the head or body. Additionally, this system is capable of non-contrast enhanced imaging, such as MRA.

MRI (magnetic resonance imaging) images correspond to the spatial distribution of protons (hydrogen nuclei) that exhibit nuclear magnetic resonance (NMR). The NMR properties of body tissues and fluids are:

• Proton density (PD) (also called hydrogen density)
• Spin-lattice relaxation time (T1)
• Spin-spin relaxation time (T2)
• Flow dynamics
• Chemical Shift

Depending on the region of interest, contrast agents may be used. When interpreted by a trained physician, these images yield information that can be useful in diagnosis.

The Vantage Titan 3T (Model MRT-3010/A5) is a 3 Tesla Magnetic Resonance Imaging (MRI) System, previously cleared under K143008. This system is based upon the technology and materials of previously marketed Canon Medical Systems and is intended to acquire and display cross-sectional transaxial, coronal, sagittal, and oblique images of anatomic structures of the head or body.

Here's an analysis of the provided text regarding acceptance criteria and study details:

Overall Assessment: The provided document is a 510(k) summary for a software modification to an existing MRI system (Vantage Titan 3T, MRT-3010/A5, V2.50). It focuses primarily on demonstrating substantial equivalence to the previously cleared version, with the addition of "mART" and "mART+" functionalities (Metal Artifact Reduction Technique and mART with View Angle Tilting).

Crucially, this document does not contain explicit, quantitative acceptance criteria for device performance in the context of metal artifact reduction, nor does it detail a clinical study with a specified sample size, expert readers, or ground truth establishment in the manner typically expected for a new diagnostic claim. Instead, it relies on demonstrating that the new functionalities do not alter the existing indications for use and that they are safe and effective through bench and volunteer imaging.

Below is a breakdown based on your requested information, highlighting what is and is not present in the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

As mentioned, explicit quantitative acceptance criteria with corresponding reported performance values are not provided in this 510(k) summary. The document states: "Bench testing utilizing both phantom and representative clinical images were obtained to demonstrate the subject device is capable of reducing metal related artifacts on MR images." This is a qualitative statement of capability rather than a measurable acceptance criterion.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not specified. The document mentions "phantom and representative clinical images" and "volunteer clinical imaging" but does not quantify the number of images or volunteers.
• Data Provenance:
  • Country of Origin: Not explicitly stated for the "representative clinical images" or "volunteer clinical imaging."
  • Retrospective or Prospective: Not explicitly stated. "Volunteer clinical imaging" would imply prospective acquisition for the purpose of the test, but the "representative clinical images" source is unclear.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified.
• Role of Experts: If experts were involved in assessing the "reduction of metal related artifacts," their role and qualifications are not detailed. The document only mentions that the images, "when interpreted by a trained physician," yield useful diagnostic information in general, not specifically for the evaluation of the mART features.

4. Adjudication Method for the Test Set

• Adjudication Method: Not specified. Given the lack of specified experts, a formal adjudication process is not described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

• MRMC Study: No, an MRMC comparative effectiveness study is not mentioned or described.
• Effect Size of Human Reader Improvement: Therefore, no effect size is reported. This submission focuses on a new imaging sequence feature (mART/mART+) rather than an AI-assisted diagnostic tool designed to directly improve human reader performance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

• This is not applicable in the typical sense of a standalone algorithm for diagnostic interpretation. The mART and mART+ functionalities are image acquisition and reconstruction techniques integrated into the MRI system. Their "performance" is assessed by the quality of the resulting image, which is then interpreted by a human. The bench and phantom testing could be considered a form of standalone technical evaluation of the image quality improvement.

7. The Type of Ground Truth Used

• Ground Truth: For the "reduction of metal related artifacts," the implied ground truth seems to be visual qualitative assessment of image quality improvements in regions affected by metal. For phantom studies, the ground truth would be the known properties of the phantom and the presence/absence of metal. For "volunteer clinical imaging," a definitive "ground truth" to quantitatively measure artifact reduction is not explicitly described (e.g., an independent reference standard for quantifying artifact severity). The focus is on demonstrating the capability of the feature to reduce artifacts.

8. The Sample Size for the Training Set

• This information is not provided. As these are image acquisition/reconstruction techniques rather than a machine learning model for diagnosis, a "training set" in the conventional AI sense may not be directly applicable or explicitly detailed in this type of submission. If any machine learning components are involved in the mART/mART+ algorithms, the details of their training are not disclosed here.

9. How the Ground Truth for the Training Set Was Established

• This information is not provided, as a training set and its ground truth establishment are not discussed in the context of this 510(k) submission.

Summary of Missing Information:

This 510(k) summary for a modified MRI device primarily relies on demonstrating that new image acquisition/reconstruction features (mART and mART+) do not alter the existing indications for use, maintain safety parameters, and are qualitatively effective at reducing metal artifacts through bench and volunteer imaging. It does not provide detailed information on quantitative acceptance criteria, large-scale clinical studies with specific sample sizes, expert ground truth establishment, or human-in-the-loop performance improvements, which are more common requirements for submissions involving new diagnostic AI algorithms.

The Vantage Titan (Model MRT-3010) is a 3 Tesla Magnetic Resonance Imaging (MRI) System, previously cleared under K152371. This system is based upon the technology, software and materials of previously marketed Toshiba MRI systems and is intended to acquire and display cross-sectional transaxial, coronal, sagittal, and oblique images of anatomic structures of the head or body.

The provided document does not contain information about specific acceptance criteria, a study proving device conformance to those criteria, or details regarding the performance of the device against such criteria. The document is a 510(k) premarket notification for a Magnetic Resonance Imaging (MRI) system (Vantage Titan 3T, MRT-3010/A7, M-Power GX).

Instead, the document focuses on demonstrating substantial equivalence to previously cleared predicate devices by outlining:

• Device Description and Changes: The submission describes the MRI system and lists software functionalities being migrated from existing cleared devices (sequence enhancements, post-processing enhancements, R-wave detection improvement).
• Safety Parameters: It compares safety parameters (static field strength, operational modes, SAR, dB/dt, emergency shutdown) of the subject device with the primary predicate device, noting they are the "Same."
• Imaging Performance Parameters: It explicitly states "No change from the previous predicate submission, K152371," indicating that the imaging performance is considered equivalent to the cleared predicate and not re-evaluated with new acceptance criteria or studies.
• Indications for Use: No changes to the previously cleared indications for use.
• Design Control Activities: Mentions risk management activities for new software functionalities and pulse sequences, confirming the test methods are the same as those in previously cleared submissions and indicating conformity with design controls.
• Safety and Standards Conformance: States the device is designed and manufactured under Quality System Regulations and ISO 13485, and conforms to applicable IEC and NEMA standards.
• Software Documentation: References FDA guidance for software documentation for a moderate level of concern.
• Conclusion: Concludes that "Based upon bench testing, phantom imaging, volunteer clinical imaging, successful completion of software validation and application of risk management and design controls, it is concluded that the subject device is safe and effective for its intended use."

Therefore, I cannot provide the requested table or detailed information on specific studies, sample sizes, expert qualifications, or adjudication methods related to specific acceptance criteria and device performance as this document addresses substantial equivalence rather than a new standalone performance evaluation against defined acceptance criteria. The "testing" mentioned is implicitly related to software validation and risk management applied to changes, assuming the underlying hardware and core imaging performance already met acceptance criteria in prior submissions.

The Vantage Titan 3T (Model MRT-3010/A5) is a 3 Tesla Magnetic Resonance Imaging (MRI) System and was cleared under K132160. This submission includes WFS (Water Fat Separation) software functionality and the optional subsystem, Saturn Gradient Option.

The provided text is a 510(k) summary for the Toshiba Medical Systems Corporation's Vantage Titan 3T Magnetic Resonance Imaging (MRI) System. This submission is for modifications to an already cleared device, specifically adding WFS (Water Fat Separation) software functionality and an optional Saturn Gradient Option. The document primarily focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study proving the new features meet specific clinical acceptance criteria.

However, I can extract information related to acceptance criteria and the type of study conducted for the new features, even if it doesn't detail specific performance metrics against clinical thresholds.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not provide a table of acceptance criteria with specific quantitative thresholds for clinical performance or corresponding reported device performance metrics for the WFS software functionality or the Saturn Gradient Option.

Instead, the submission states:

• "This testing demonstrated that the software performed as specified and did not raise new issues of safety and effectiveness."
• "The additional software packages are work flow improvements and their performance was demonstrated to be equal to or better than the current methods for obtaining the same results."

These statements indicate that the "acceptance criteria" for these new features were likely focused on:

• Functionality: The WFS software correctly separates water and fat images as intended.
• Safety: No new safety concerns are introduced by the changes.
• Equivalence/Non-inferiority: Performance is at least as good as, or better than, existing methods or the predicate device's performance for the same tasks.

2. Sample Size Used for the Test Set and Data Provenance

• Test Set Sample Size: The document only mentions "representative volunteer images" for the WFS software functionality. No specific number for the volunteer images or phantom studies is provided.
• Data Provenance: Not explicitly stated, but typically, testing for such devices is conducted by the manufacturer, often using their own facilities or clinical partners. The country of origin for the manufacturing site is Japan. The nature of the study (retrospective/prospective) is not specified, but for new feature validation, it would typically involve prospective data acquisition.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

The document does not specify the number of experts used or their qualifications for establishing ground truth for the "representative volunteer images" or phantom studies. However, the "Indications for Use" section mentions that images are "interpreted by a trained physician," implying that expert interpretation is crucial for diagnostic use. For the validation of image quality, typically radiologists or other medical imaging specialists would be involved.

4. Adjudication Method for the Test Set

The document does not describe any specific adjudication method (e.g., 2+1, 3+1) for evaluating the test set for the new features.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This submission is for an MRI system with new software features, not an AI-assisted diagnostic tool. Therefore, an MRMC comparative effectiveness study regarding human reader improvement with/without AI assistance is not applicable and was not performed. The "WFS (Water Fat Separation)" functionality is an image processing technique, not an AI interpretation tool.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

Yes, in a sense. The testing for the WFS software itself, particularly the "phantom studies," would constitute an evaluation of the algorithm's performance in a standalone manner, assessing its ability to correctly separate water and fat signals. The "representative volunteer images" would also assess the algorithm's performance on human data, but the evaluation of these images would implicitly involve a human observer (e.g., to confirm visual quality and separation). The document states, "This testing demonstrated that the software performed as specified," implying that the software's output was directly evaluated.

7. The Type of Ground Truth Used

• Phantom Studies: For phantom studies, the ground truth is typically known and engineered into the phantom itself (e.g., known fat/water ratios in different compartments). This provides an objective measure of the algorithm's accuracy in separating these components.
• Volunteer Images: For "representative volunteer images," the ground truth would likely be established through visual assessment by experts (e.g., confirming clear water/fat separation, absence of artifacts, and diagnostic quality) or potentially by comparing with established imaging sequences known to provide good fat/water separation. Pathology or outcomes data would not be the direct ground truth for this type of image processing feature.

8. The Sample Size for the Training Set

The document does not provide any information about a training set since the WFS functionality and gradient option are described as "software functionality" and "optional subsystem" being added to an existing, cleared MRI system. It does not suggest these features involved a machine learning model that required a specific training set in the conventional sense. If the WFS algorithm development involved any iterative refinement, details are not provided here.

9. How the Ground Truth for the Training Set Was Established

As no training set is described for a machine learning model, this question is not applicable based on the provided text.

Analysis of K132160 for Acceptance Criteria and Study Details

The provided document K132160 relates to a 510(k) premarket notification for software functionalities added to the Toshiba Vantage Titan 3T MRI system (Model MRT-3010/A5). It's important to note that this submission primarily concerns software changes and their impact on safety and performance parameters, rather than a new diagnostic algorithm or a comparative effectiveness study for a new clinical indication. Therefore, the typical structure for reporting acceptance criteria and study details for an AI/algorithm-driven diagnostic device showing clinical performance metrics may not fully apply in this context.

Based on the document, the "acceptance criteria" and "device performance" are primarily framed around compliance with established safety standards and maintaining equivalence in imaging performance compared to the predicate device.

1. Table of Acceptance Criteria and Reported Device Performance

Given that this submission is for software updates to an existing MRI system, the acceptance criteria are largely focused on demonstrating that the updated system continues to meet safety and performance standards, or improves on flexibility without compromising safety. There aren't specific quantitative accuracy metrics for diagnosing a condition, but rather operational and safety specifications.

The Vantage Titan 3T (Model MRT-3010/A5) is a 3 Tesla Magnetic Resonance Imaging (MRI) System(K113093). Four software packages (Positioning Assist for Cardiac, Diffusion Tensor Tractography (DTT) , Cardiac Function Analysis, and Image filter EM AIDR are added to Vantage Titan 3T.

The provided text is a 510(k) summary for the Toshiba Vantage Titan 3T, v2.0 (MRT-3010/A5) MRI system. It describes the device and its intended use, focusing on software package additions to an already cleared predicate device (K113093). The document primarily addresses safety parameters and outlines the process of demonstrating substantial equivalence to the predicate device, especially regarding design control activities and adherence to recognized standards.

However, the document does not contain the specific information required to complete the table for acceptance criteria and device performance, nor does it provide details about a study designed to prove the device meets specific acceptance criteria in the way described in the prompt.

Here's why and what information can be extracted or inferred:

• Acceptance Criteria and Reported Device Performance: This section is not explicitly present. The document focuses on showing the new device is "substantially equivalent" to a predicate device by comparing safety parameters (which are identical) and outlining that the new software additions are consistent with the predicate's intended use. It doesn't define new performance-based acceptance criteria for the added software packages (Positioning Assist for Cardiac, DTT, Cardiac Function Analysis, Image filter EM AIDR) nor report specific performance metrics against such criteria.
• Study Design Information: The document states, "The test methods used are the same as those submitted in the previously cleared submissions (K113093). A declaration of conformity with design controls is included in this submission." This indicates that the validation relied on existing testing methodologies and design controls from the predicate device, rather than a new standalone study with a defined sample size, ground truth, experts, or adjudication methods for the specific software additions.

Therefore, the table and most of the detailed study questions cannot be answered from the provided text.

Inference/Extracted Information based on the provided text:

While a direct study with acceptance criteria is not detailed, the text implies that the "acceptance criteria" for the new software features were essentially demonstrating that they maintained the overall safety and imaging performance of the predicate device and performed their described functions as intended, within the framework of existing design controls. The study that "proves" this is the demonstration of substantial equivalence to the predicate device K113093, adhering to international standards for MR devices and software development.
