The description mentions "semi-automatic detection of the ROI boundary" and a "Polyp Enhanced Viewing Filter" that "identifies intra-colonic filling defects". While these features involve image analysis and potentially pattern recognition, the summary does not explicitly state that AI or ML algorithms are used for these functions. The description of the filter's adjustability based on sphericity, flatness, and diameter range suggests rule-based or traditional image processing techniques rather than typical ML approaches. Without further information, it's not possible to definitively confirm or deny the presence of AI/ML.
No
The device is an image analysis software application used to assist clinicians in the evaluation of polyps, cancers, and other lesions. It does not directly treat or diagnose a disease state, which are characteristics of a therapeutic device.
Yes
The device assists radiologists and other clinicians in the "evaluation of polyps, cancers and other lesions" derived from CT scans. This indicates it is used to identify or analyze disease, which is a diagnostic purpose.
Yes
The device is explicitly described as a "PC-based, stand-alone, non-invasive, image analysis software application" and a "software tool." The description focuses solely on software functionalities for image processing and visualization, with no mention of accompanying hardware components required for its operation beyond a standard PC.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device function: Colon CAR 1.2 is an image analysis software application that processes medical images (CT scans) of the colon. It assists clinicians in evaluating polyps and other lesions by providing visualization and measurement tools.
- Lack of biological sample analysis: The device does not analyze any biological samples from the patient. Its input is image data, not biological material.
Therefore, Colon CAR 1.2 falls under the category of medical image processing software, not in vitro diagnostics.

Intended Use / Indications for Use
Colon CAR 1.2 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 single or double seed points followed by interactive fine-tuning the boundaries of the ROI. It also allows for the simultaneous display of supine and prone images.
Colon CAR 1.2 contains additional imaging tools which allow enhancement of specified features, and which the clinician can view simultaneously with the non-enhanced view.

Device Description
Colon CAR™ (Computer Assisted Reader) 1.2 is a software tool designed to assist radiologists and other clinicians in the evaluation of polyps 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 measurement of polyp characteristics such as size and volume. The further feature of Colon CAR™ 1.2 as compared to the cleared device is a Polyp Enhanced Viewing Filter (PEV), the results of which are presented in a Joint Reader filter view (enhanced and non-enhanced data viewed simultaneously). The PEV filter identifies intra-colonic filling defects protruding into the colonic lumen, thereby highlighting potential polyp candidates for further interrogation by the reporting radiologist. This filter is fully adjustable and, in deciding the desired characteristics of the objects to be highlighted, the radiologist may specify the degree of object sphericity (or roundness), the height of the protruding object in relation to its base (object 'flatness') as well as select an approximate object diameter range.

Device Description:
Colon CAR™ (Computer Assisted Reader) 1.2 is a software tool designed to assist radiologists and other clinicians in the evaluation of polyps 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 measurement of polyp characteristics such as size and volume. The further feature of Colon CAR™ 1.2 as compared to the cleared device is a Polyp Enhanced Viewing Filter (PEV), the results of which are presented in a Joint Reader filter view (enhanced and non-enhanced data viewed simultaneously). The PEV filter identifies intra-colonic filling defects protruding into the colonic lumen, thereby highlighting potential polyp candidates for further interrogation by the reporting radiologist. This filter is fully adjustable and, in deciding the desired characteristics of the objects to be highlighted, the radiologist may specify the degree of object sphericity (or roundness), the height of the protruding object in relation to its base (object 'flatness') as well as select an approximate object diameter range.
Intended Use:
Colon CAR 1.2 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.
