Intended Use

The BodyTom 64 system is intended to be used for x-ray computed tomography applications for anatomy that can be imaged in the 85cm aperture. The CT system is intended to be used for both pediatric and adult imaging and as such has preset dose settings based upon weight and age. The CT images can be obtained either with or without contrast.

BodyTom 64 system can be used for low dose lung cancer screening. The screening must be performed in compliance with the approved and established protocols as defined by professional medical societies.

Device Description

BodyTom 64 computed tomography (CT) system provides the same functionality as the previous version of the device BodyTom 64 (K213649). Both CT systems are identical in terms of the high resolution, multi row, 85 cm bore, and 60 cm field of view. The lightweight translating gantry consists of a rotating disk with a solid-state x-ray generator, Gd202S detector array, collimator, control computer, communications link, power slipring, data acquisition system, reconstruction computer, power system, brushless DC servo drive system (disk rotation) and an internal drive system (translation). The power system consists of batteries which provide system power while unplugged from the charging outlet. The system has the necessary safety features such as the emergency stop switch. x-ray indicators, interlocks, patient alignment laser and 110% x-ray timer. The gantry has retractable rotating caster wheels and electrical drive system so the system can be moved easily to different locations. The interventional radiology package should not be used in an operating room during surgery.

AI/ML Overview

The provided document, a 510(k) Premarket Notification from the FDA, states that the "BodyTom 64" device is "substantially equivalent" to a predicate device (BodyTom 64, K213649) and does not provide an extensive acceptance criteria table or detailed study results for a new clinical performance study.

Typically, when a device is found to be "substantially equivalent" based on technological characteristics and performance testing to an already cleared predicate, the FDA does not require new, large-scale clinical studies with human subjects, especially if the changes are limited to software updates and new features that do not raise new questions of safety or effectiveness. The document instead focuses on demonstrating adherence to recognized standards, quality system regulations, and bench testing to show that the modified device performs comparably and safely.

Therefore, many of the requested details about acceptance criteria, detailed performance metrics, sample sizes, expert ground truth establishment, MRMC studies, or multi-reader studies are not explicitly stated or applicable in this type of 510(k) submission where substantial equivalence is being demonstrated based on non-clinical performance and technological characteristics.

However, based on the information provided, here's what can be extracted and inferred:

1. A table of acceptance criteria and the reported device performance:

The document primarily states that the device meets existing standards and performs comparably to its predicate. Specific quantitative acceptance criteria for clinical performance are not listed with corresponding results because the submission focuses on substantial equivalence through technical verification.

Acceptance Criterion (Inferred from testing types)Reported Device Performance
Image Quality Metrics: - Noise - Slice thickness - Low contrast resolution - High contrast resolution - Radiation metrics - Modulation transfer function (MTF)"Imaging metrics successfully demonstrated that the proposed device has comparable image quality with its previous version, predicate device (K213649) and meets all the image quality criteria that are used for testing."
Electrical Safety / Electromagnetic Compatibility (EMC/EMI)"proved to be in compliance with IEC 60601-1-2. and IEC 60601-1-2. and IEC 60601-2-44."
Software Functionality and Safety"Software is critical to the operation of the BodyTom 64 CT system and a malfunction or design flaw in the software could result in delay in delivery of appropriate medical care. As such, the risk management analysis identified potential hazards which were controlled and mitigated during development of BodyTom 64. The verification/validation testing ensured substantial equivalence of BodyTom 64." "The proposed BodyTom 64 device demonstrated that the new features did not exhibit any negative effects on the requirements in place, as well as they did not exhibit any concerns." "The proposed BodyTom 64 device was shown to meet all requirements and to not have any impact on imaging."
Mechanical Safety"To minimize electrical, mechanical and radiation hazards, NeuroLogica adheres to recognized and established industry practices."
Compliance with Federal Diagnostic Equipment Performance Standard and applicable regulations (21 CFR §1020.30 and §1020.33)"All components...are certified to meet those requirements."
Compliance with Quality System Regulations and ISO 13485:2016"BodyTom 64 CT system is designed and manufactured to comply with the FDA Quality System Regulations and ISO 13485:2016 requirements."

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size: Not applicable/not specified for a clinical test set since this submission relies on bench testing (phantom image quality tests), software verification/validation, and regulatory compliance, rather than a clinical study with human patients.
  • Data Provenance: Not applicable, as no patient data was used for this substantial equivalence demonstration. The data pertains to engineering and phantom testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

  • Not applicable. Ground truth, in the context of phantom testing for image quality, is established by known physical properties of the phantoms and measurements of the system's output against defined engineering specifications, not by expert human interpretation.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • Not applicable, as no human reader studies requiring adjudication were conducted.

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. This submission does not describe an MRMC study. The device is a CT system with software functionality updates, not an AI-assisted diagnostic tool that aids human readers in interpretation.

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

  • Not applicable in the context of an algorithm's diagnostic performance. The "performance" being evaluated is the technical and physical output of the CT system and its software, not a diagnostic algorithm.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

  • The "ground truth" for the performance described generally refers to:
    • Engineering Specifications: For image quality metrics (noise, resolution, etc.), the performance is measured against established quantitative specifications derived from physical principles and industry standards using phantoms.
    • Regulatory Requirements & Harmonized Standards: For safety (electrical, mechanical, radiation) and quality, the ground truth is compliance with the detailed requirements outlined in standards like IEC 60601 series, ISO 14971, IEC 62304, and FDA regulations (21 CFR §1020.30, §1020.33).
    • Predicate Device Performance: Implicitly, the performance of the predicate device (K213649) serves as a benchmark for "comparable image quality."

8. The sample size for the training set

  • Not applicable. This device is a CT scanner, not a machine learning algorithm that requires a "training set" for its core function of image acquisition and reconstruction. The software updates mentioned likely relate to system control, user interface, or image processing, which undergo traditional software verification and validation, not machine learning model training.

9. How the ground truth for the training set was established

  • Not applicable, as there was no training set in the context of machine learning model development.
