More Information

Not Found

No
The document describes an "iterative reconstruction algorithm" (FIRST 2.0) which is a common image processing technique in CT, but it does not mention AI, ML, or any related concepts like neural networks, training data, or performance metrics typically associated with AI/ML models.

No
The device is described as a CT scanner indicated for acquiring and displaying cross-sectional volumes and improving image quality, which are diagnostic functions, not therapeutic.

Yes

The device acquires and displays cross-sectional volumes of the whole body and organs, which are then used by a trained physician to perform specialized studies. The mention of "representative diagnostic images" further confirms its role in aiding diagnosis.

No

The device description explicitly states it is a "whole body multi-slice helical CT scanner, consisting of a gantry, couch and a console used for data processing and display," which are hardware components. While it includes software (FIRST 2.0), it is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use describes acquiring and displaying cross-sectional volumes of the body for diagnostic imaging. This is a function of medical imaging devices, not IVDs.
  • Device Description: The device is described as a whole body multi-slice helical CT scanner. CT scanners are medical imaging devices that use X-rays to create images of the inside of the body.
  • No mention of in vitro testing: There is no mention of analyzing samples (like blood, urine, or tissue) outside of the body, which is the defining characteristic of an IVD.
  • Focus on imaging: The entire description and performance studies revolve around image acquisition, processing, and quality.

IVDs are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform such functions.
