No
The description focuses on image subtraction and registration, which are standard image processing techniques, and does not mention AI, ML, or related concepts.
No
The device aids in visualization and diagnostic interpretation, it does not directly treat or prevent a disease or condition.
No
The software aids in visualization of lung parenchyma enhancement by subtracting volumes. It is a post-processing tool that manipulates images for better viewing, but it does not diagnose medical conditions.
Yes
The device is described solely as "post-processing software" that performs image subtraction and registration. There is no mention of any accompanying hardware components or hardware-specific functions beyond processing existing CT images.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens derived from the human body. The description clearly states that this software processes imaging data (Computed Tomography scans) of the lung. It does not analyze blood, tissue, urine, or any other biological specimen.
- The intended use is to aid in visualization of lung parenchyma enhancement. This is a diagnostic aid based on image processing, not a test performed on a biological sample to diagnose a condition.
- The device description focuses on post-processing of image data. It talks about subtracting image information and using registration software to match data sets. This is characteristic of medical imaging software, not IVD devices.
In summary, this device is a medical imaging software intended to assist in the interpretation of CT scans, not a device that performs tests on biological specimens.
