Yes
The "Mentions AI, DNN, or ML" section explicitly states that the device "Automatically segments the calcium area of the coronary artery based on deep learning" and references a predicate device that uses an "artificial intelligence algorithm".
No.
The device provides quantitative analysis and risk stratification based on existing CT scans, which supports healthcare professionals in diagnosis and decision-making, but it does not directly treat or prevent a disease or condition.
Yes
The device uses non-contrast non-gated Chest CT scans to quantitatively analyze calcified plaques in the coronary arteries, calculate the Agatston score for coronary artery calcification, segment and evaluate arteries, and provide risk stratification based on calcium score, gender, and age, which are all diagnostic functions aiding in the identification and assessment of a medical condition.
Yes
The device description explicitly states "The AVIEW CAC is a software product that can be installed on a PC." and describes its functions as software-based image processing, analysis, and display. While it interacts with CT data, it does not include or require specific hardware components beyond a standard PC for installation and operation.
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.
- AVIEW CAC's Function: AVIEW CAC analyzes medical images (CT scans) of the coronary arteries. It does not perform tests on biological samples.
- Intended Use: The intended use clearly states that it provides "quantitative analysis of calcified plaques in the coronary arteries using non-contrast non-gated Chest CT scans." This is image analysis, not in vitro testing.
- Device Description: The device description reinforces that it's a "software product" that "shows images taken with the interface from various storage devices using DICOM 3.0" and offers functions for "reading, manipulation, analyzing, post-processing, saving, and sending images."
Therefore, AVIEW CAC falls under the category of medical image analysis software, not an In Vitro Diagnostic device.
No
The input states "Control Plan Authorized (PCCP) and relevant text: Not Found", which indicates the letter does not contain any explicit statement about FDA review and approval or clearance of a PCCP for this device.
Intended Use / Indications for Use
AVIEW CAC provides quantitative analysis of calcified plaques in the coronary arteries using non-contrast non-gated Chest CT scans. It enables the calculation of the Agatston score for coronary artery calcification, segmenting and evaluating the right coronary artery and left coronary artery. Also provide risk stratification based on calcium score, gender, and age, offering percentile-based risk categories by established guidelines. Designed for healthcare professionals, including radiologists and cardiologists, AVIEW CAC supports storing, inquiring, and displaying CT data sets on-premises, facilitating access through mobile devices and Chrome browsers. AVIEW CAC analyzes existing non-contrast/non-gated Chest CT studies that include the heart of adult patients above the age of 40. Also, the device's use should be limited to CT scans acquired on General Electric (GE) or its subsidiaries (e.g., GE Healthcare) equipment. Use of the device with CT scans from other manufacturers has not been validated or recommended.

AVIEW provides CT values for pulmonary tissue from CT thoracic and cardiac datasets. This software can be used to support the physician providing quantitative analysis of CT images by image segmentation of sub-structures in the lung, lobe, airways, fissures completeness, cardiac, density evaluation, and reporting tools. AVIEW is also used to store, transfer, inquire and display CT data set on-premises and as a cloud environment to allow users to connect by various environments such as mobile devices and Chrome browsers. Converts the sharp kernel to soft kernel for quantitative analysis of segmenting low attenuation areas of the lung. Characterizing nodules in the lung in a single study or over the time course of several thoracic studies. Characterizations include nodule type, location of the nodule, and measurements such as size (major axis, minor axis), estimated effective diameter from the volume of the nodule, the volume of the nodule, Mean HU(the average value of the CT pixel inside the nodule in HU), Minimum HU, Max HU, mass(mass calculated from the CT pixel value), and volumetric measures(Solid major; length of the longest diameter measure in 3D for a solid portion of the nodule, Solid 2nd Major: The size of the longest diameter of the solid part, measured in sections perpendicular to the Major axis of the solid portion of the nodule), VDT (Volume doubling time), and Lung-RADS (classification proposed to aid with findings.). The system automatically performs the measurement, allowing lung nodules and measurements to be displayed and, integrate with FDA certified Mevis CAD (Computer aided detection) (K043617). It also provides the Agatston score, volume score, and mass score by the whole and each artery by segmenting four main arteries (right coronary artery, left main coronary, left anterior descending, and left circumflex artery). Based on the calcium score provides CAC risk based on age and gender. The device is indicated for adult patients only. HealthCCSng
The HealthCCSng device is intended for use as a non-invasive post-processing software to evaluate calcified plaques in the coronary arteries, which present a risk for coronary artery disease. The software generates an estimated coronary artery calcium detection category.
The HealthCCSng device analyzes existing non-cardiac-gated CT studies that include the heart of adult patients above the age of 30. The device generates a threecategory output representing the estimated quantity of calcium detected together with preview axial images of the detected calcium meant for informational purposes only. The device output will be available to the radiologist as part of their standard workflow. The HealthCCSng results are not intended to be used on a stand-alone basis for risk attribution, clinical decision-making or otherwise preclude clinical assessment of CT studies
