The document describes a standard ultrasound imaging system with 3D capabilities, but there is no mention of AI or ML in the device description, intended use, or performance studies. The testing focuses on electrical safety, imaging performance using phantoms, and acoustic output, which are typical for traditional ultrasound devices.
No
The device is described as an imaging system used to aid in the detection and assessment of abnormalities, not for treatment.
Yes
The "Intended Use / Indications for Use" states that the device is an "aid in the detection and assessment of physical and functional abnormalities using established diagnostic criteria".
No
The device description explicitly mentions obtaining and displaying images and Doppler spectra, and the performance studies include electrical safety and imaging performance tests using a "scanner" and "transducers," which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use describes the device for imaging organs and structures using ultrasound for diagnostic purposes. This involves visualizing internal anatomy.
- Device Description: The description details an ultrasound system that generates and displays images (B-scan, M-mode, Doppler, Color Flow, 3D). This is consistent with an imaging device.
- Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not interact with or analyze such specimens. It uses external energy (ultrasound) to create images of internal structures.
Therefore, this device falls under the category of a medical imaging device, not an In Vitro Diagnostic device.
