MedicColon I is a PC-based, stand-alone, non-invasive, image analysis software application for the display and visualization of 2D and 3D medical image data of the colon derived from CT scans, for the purpose of assisting radiologists and other clinicians in the evaluation of polyps, cancers and other lesions. The software provides functionality for the user to extract the region of interest (ROI) either manually using a drawing tool, or "semi-automatically" through the user selecting a seed point followed by interactive fine-tuning the boundaries of the ROI. It also allows for the simultaneous display of supine and prone images

Device Description

MedicColon™ 1 is a software tool designed to assist radiologists and other clinicians in the evaluation of polyps, cancers and other lesions in the colon. The software allows the user to select Regions of Interest either manually or by selecting a single or double seed point, followed by semi-automatic detection of the ROI boundary. It provides 2D and 3D visualisation of polyps and other lesions, and measurement of polyp characteristics such as size and volume.

AI/ML Overview

The provided document does not contain acceptance criteria or a study proving the device meets them. This 510(k) Summary of Safety and Effectiveness document instead focuses on establishing substantial equivalence to predicate devices for the MedicColon™ Release 1 software.

Here's what the document does provide:

Device Description: MedicColon™ 1 is a software tool to assist radiologists in evaluating polyps, cancers, and other lesions in the colon from CT scans. It offers 2D and 3D visualization, semi-automatic ROI selection, and measurement of polyp characteristics.
Intended Use: PC-based, stand-alone, non-invasive image analysis software for display and visualization of 2D and 3D CT colon data to assist clinicians in evaluating polyps, cancers, and other lesions.
Predicate Devices: VOXAR VC, MODEL 1.0 (K012072) and SIEMENS SYNGO COLONOGRAPHY SOFTWARE PRODUCT (K030982).
Conclusion of Substantial Equivalence: MedicColon 1 is considered substantially equivalent to the predicate devices with respect to safety and effectiveness, and does not raise new safety risks. Test data were provided to validate performance and substantial equivalence.

Therefore, it is impossible to answer the requested questions about acceptance criteria and study details based on the provided text. The document states that "Test data are provided to validate the performance of the system and its substantial equivalence to the predicate devices," but does not describe the nature of this test data, the studies conducted, or any specific performance metrics or acceptance criteria.

Device Description:

Intended Use:

Comparison to Predicate Device:

As in the predicate devices, Voxar VC Model 1.0 and Siemens Syngo Colonography Product. MedicColon 1 assists users in assessing CT images for the identification and evaluation of polyps, cancers and other lesions in the colon.

Test data are provided to validate the performance of the system and its substantial equivalence to the predicate devices. The functional features and the intended use of MedicColon 1 are substantially equivalent to the predicate devices.

Safety:

A comprehensive hazard analysis was carried out on MedicColon 1, which concluded that any residual risks were as low as reasonably practicable and judged as acceptable when weighed against the intended benefits of use of the system.

Conclusion:

MedicColon 1 does not raise any new potential safety risks and is equivalent in performance to existing legally marketed devices. MedicColon 1 is therefore substantially equivalent with respect to safety and effectiveness to the predicate devices.

Dear Ms. Mac Donald:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
