The system also provides 3D B-mode imaging for high quality ultrasound acquisition of anatomical volumes. The technology employed is volume-swept 3D ultrasound.
This document is a 510(k) Summary for the KOELIS TRINITY / 3D PROSTATE SUITE device. It establishes substantial equivalence to previously cleared devices rather than providing performance data against specific acceptance criteria for new features or AI-driven improvements. As such, it does not contain the detailed study information typically associated with proving a device meets acceptance criteria for novel algorithms, especially those involving AI.
Therefore, many of the requested fields cannot be directly populated from the provided text. The device is primarily an ultrasound system with associated software for processing and visualizing images, and the application focuses on expanding its indications for use and adding a new probe. The "Summary of Clinical Tests" explicitly states: "The subject of this premarket submission did not require clinical studies to support substantial equivalence."
Based on the provided text, here's an attempt to answer the questions:
1. A table of acceptance criteria and the reported device performance
The document does not provide a table of acceptance criteria with reported quantitative performance metrics for the TRINITY / 3D PROSTATE SUITE in the context of novel algorithmic performance or AI. The acceptance is based on demonstrating substantial equivalence to existing predicate devices for similar clinical applications and modalities, and compliance with various safety and performance standards.
The criteria for acceptance appear to be:
- Substantial Equivalence: Demonstrated through comparison of intended use, imaging capabilities, technological characteristics, scientific backgrounds, safety, and effectiveness to predicate devices (K160357 TRINITY and K160182 Logiq S7 expert).
- Safety Standards Compliance: Meeting voluntary standards for acoustic output, biocompatibility, cleaning/disinfection, thermal, electromagnetic, and mechanical safety (e.g., AAMI/ANSI ES60601-1, IEC60601-1-2, IEC60601-2-37, NEMA UD 3, ISO10993-1, NEMA UD 2, ISO14971, NEMA DICOM Set).
- Quality Assurance Measures: Application of risk analysis, requirements reviews, design reviews, varying levels of testing (unit, integration, final acceptance, performance, safety).
Since no new algorithmic performance (e.g., AI accuracy) is being claimed or evaluated, there are no reported quantitative performance metrics against these criteria beyond the statement that the device is "as safe, as effective, and performance is substantially equivalent to the predicate devices."
2. Sample size used for the test set and the data provenance
As stated, "The subject of this premarket submission did not require clinical studies to support substantial equivalence." Therefore, there is no clinical "test set" with patient data in the typical sense for evaluating a novel algorithm's performance. The "testing" referred to is against engineering and safety standards, not clinical performance on a dataset of images with ground truth.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable, as no clinical test set with ground truth established by experts for algorithmic performance evaluation was described as part of this submission.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable.
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
No such study was conducted or reported in this 510(k) summary. The device's substantial equivalence is based on its core functionality as an ultrasound system and imaging processing system, not on AI assistance to human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not an AI-driven diagnostic algorithm. It's an imaging system and processing software. Therefore, the concept of "standalone performance" for an AI algorithm is not applicable here. The system's performance is intrinsically tied to its ability to generate, process, and display images for human interpretation and procedures.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable, as no clinical performance study involving ground truth for an algorithm was conducted.
8. The sample size for the training set
Not applicable, as this is not an AI/ML submission describing a model trained on a dataset.
9. How the ground truth for the training set was established
Not applicable.

This document is a 510(k) Premarket Notification from the FDA regarding the TRINITY Ultrasound and Medical Imaging Processing System. While it provides detailed information about the device's intended use, technological characteristics, and compliance with safety standards, it explicitly states that "The subject of this premarket submission did not require clinical studies to support substantial equivalence."
Therefore, I cannot provide information regarding acceptance criteria and a study proving the device meets those criteria because a clinical study was not performed as part of this submission. The submission relies on demonstrating substantial equivalence to predicate devices, not on a new clinical study.
Here's what can be inferred from the document regarding the information requested, based on the absence of a clinical study:
1. A table of acceptance criteria and the reported device performance:
- This information is not provided because no clinical study was conducted. The document focuses on demonstrating equivalence to predicate devices based on technical specifications and non-clinical tests.
2. Sample size used for the test set and the data provenance:
- Not applicable, as no clinical test set was used for a study proving device performance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable, as no clinical test set requiring ground truth was used for a study proving device performance.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable, as no clinical test set requiring adjudication was used for a study proving device performance.
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:
- Not applicable. No MRMC study was performed. The device is an ultrasound system and processing software, not an AI-assisted diagnostic tool in the typical sense that would necessitate an MRMC study comparing human readers with and without AI assistance for a specific clinical task.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. The TRINITY system is an ultrasound and medical imaging processing system intended to be used by clinicians. It is not an algorithm-only standalone diagnostic tool. Its performance is inherent to the generation, visualization, and recording of ultrasound images, and processing of 3D digital ultrasound images for tasks like organ mapping (with the 3D PROSTATE SUITE SOFTWARE).
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable, as no clinical study required establishing ground truth for performance evaluation of "new" clinical results.
8. The sample size for the training set:
- Not applicable, as no clinical study with a training set was performed for this submission. The device leverages existing technology and previously cleared software (UROSTATION - 3D PROSTATE SUITE, K131448).
9. How the ground truth for the training set was established:
- Not applicable, as no clinical study with a training set was performed for this submission.
Summary from the document:
- Basis for Approval: Substantial equivalence to predicate devices (LOGIQ S7 Expert and LOGIQ S7 Pro (GE Healthcare) K141261, and UROSTATION - 3D PROSTATE SUITE (KOELIS) K131448).

UROSTATION - 3D PROSTATE SUITE with MRI/3DTRUS fusion option and with Second Look 3DTRUS fusion option is a computer-based software application intended to process, visualize and record 3D digital ultrasound images of the prostate.
UROSTATION - 3D PROSTATE SUITE with MRI/3DTRUS fusion option and with Second Look 3DTRUS fusion option is intended to be used by physicians in the clinic or hospital for 2D and 3D visualization of the prostate gland and for the 3D transrectal ultrasound based fusion of multiple imaging modalities (ultrasound, MRI) in order to map such prostate gland. Additional software features include patient data management, multimodal data communication, multiplanar reconstruction, surface and volume rendering, organ delineation, region of interest delineation, 3D image registration and data reporting.
UROSTATION - 3D PROSTATE SUITE is a computer-based software application designed to process, visualize and record 3D digital ultrasound images of the prostate, and to manage patient and clinical data in the context of transrectal prostate biopsy. Software options provide the fusion of 3DTRUS with MRI or with other 3DTRUS modalities.
Hardware Platform and Operating System
The application runs on a standard Personal Computer under Microsoft Windows® operating system (version 7 or higher).
Peripheral and accessories
The application is controlled by a footswitch and manual input devices (mousc, kevboard),
It is designed to work in connection with commercially available 3D ultrasound scanners with Ethernet connection, 3D transrectal ultrasound probe and needle guide.
Software Features
UROSTATION - 3D PROSTATE SUITE implements image fusion and display algorithms to provide 3D representation of prostate biopsies.
A typical workflow enables the physician to intraoperatively visualize the 3D mapping of biopsies with respect to a 3DTRUS reference image of the patient's prostate.
For that purpose. 3D digital images may be transferred at any time from the 3D ultrasound scanner to the Urostation for registration and display, while the physician keeps track of the organ on the ultrasound scanner using the usual 2D live B mode.
Optionally, MRI/3DTRUS fusion allows the elastic registration of the 3DTRUS reference image with other imaging modalities (MRI here) in order to display the 3D biopsy mapping on multiple imaging modalities.
Optionally, Second Look 3DTRUS Fusion allows the elastic registration of the 3DTRUS reference image with a previously acquired 3DTRUS reference image of the same patient in order to superimpose two 3D biopsy mappings on a unique 3DTRUS reference image.
Alternatively, UROSTATION - 3D PROSTATE SUITE also provides a review mode that allows the mapping of histologic results on the said 3D reference image of the patient's prostate. Patient information, images and 3D biopsy mapping may be stored or printed for future retrieval and examination.
The acceptance criteria for the UROSTATION - 3D PROSTATE SUITE with MRI/3DTRUS fusion option and Second Look 3DTRUS fusion option are based on its performance and accuracy in image fusion and organ tracking. The device aims to assist physicians in targeting different regions of the prostate by registering biopsy cores and optionally MR lesions on a reference 3DTRUS image.
The studies presented validate the performance and accuracy of the KOELIS fusion technology on both phantom and patient data.

- Elastic MR/3DTRUS image fusion (Brolis et al, 2012): "Physicians" identified and approved 112 landmark pairs. Specific number and qualifications beyond "physicians" are not provided.
- Elastic 3DTRUS/3DTRUS image fusion and organ tracking (Baumann et al, 2012): Not explicitly stated how ground truth for accuracy evaluation (using fiducials) was established, but implies fiducial markers as objective ground truth.
- Targeting Accuracy of Urostation (Ukimura et al, 2012): The ground truth for lesion location in phantoms is inherent to the phantom design. The accuracy of biopsy "hitting the lesion" is a direct measurement based on the physical phantom. No external experts are mentioned for ground truth establishment for this specific study.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not explicitly stated for any of the studies. For the clinical validation in Brolis et al., "landmark pairs were identified and approved by physicians," which suggests a consensus or verification process, but the specific method is not detailed.
-
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:
- The provided information does not include an MRMC comparative effectiveness study that assesses the improvement of human readers with AI assistance versus without. The studies focus on the intrinsic accuracy and performance of the fusion technology itself.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Yes, the "Performance summary" section primarily describes standalone algorithm performance in terms of registration accuracy, error rates, and hit probabilities for both fusion capabilities and targeting accuracy. The Brolis et al. study on "simulated deformations" and the Baumann et al. study on "system robustenss" and "accuracy was evaluated to 0.76mm±0.52mm using fiducials" directly assesses the algorithm's performance. Similarly, the phantom study by Ukimura et al. measures the algorithmic accuracy of targeting.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Brolis et al. (Elastic MR/3DTRUS): Expert-identified landmark pairs and contours (from 3DTRUS patient volumes) for registration accuracy.
- Baumann et al. (Elastic 3DTRUS/3DTRUS): Fiducials (objective physical markers) for evaluating tracking accuracy.
- Ukimura et al. (Targeting Accuracy): Physical lesion locations within prostate phantoms. Biopsy success was likely determined by confirming needle placement relative to the known lesion locations in the phantoms.
-
The sample size for the training set:
- The document does not explicitly state the sample size for the training set for any of the algorithms. These studies primarily describe validation/testing.
-
How the ground truth for the training set was established:
- Since the training set size and details are not provided, how its ground truth was established is also not detailed in this document.
