No
The summary does not mention any AI or ML capabilities, and the device description focuses on standard ultrasound technology and software.
No
The device is described as an "Ultrasound Imaging System" intended for "imaging" and "fluid flow analysis," indicating its purpose is diagnostic, not therapeutic.
Yes
The device is described as an "Ultrasound Imaging System" intended for use by "qualified physicians and healthcare professionals" for "ultrasound scan process for evaluation by ultrasound imaging system or fluid flow analysis of the human body." It explicitly lists various "Specific clinical applications and exam types" across multiple anatomical sites (e.g., Fetal, General abdominal imaging, Cardiac, etc.). These applications involve acquiring and displaying "hi-resolution, real-time ultrasound data" for medical assessment, which is the definition of a diagnostic device.
No
The device description explicitly states that the system consists of "a series of wireless transducers" and "houses a built-in battery, multichannel beamformer, prescan converter and Wi-Fi components," which are hardware components. While it utilizes software on a mobile device, it is not solely software.
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: The description clearly states that this is an Ultrasound Imaging System. Ultrasound is a non-invasive imaging technique that uses sound waves to create images of internal body structures. It does not involve testing samples taken from the body.
- Intended Use: The intended use describes the system being used for "evaluation by ultrasound imaging system or fluid flow analysis of the human body" and lists various anatomical sites for imaging. This aligns with the function of an ultrasound device, not an IVD.
Therefore, the Ultrasound Imaging System (Model: 128 Series) and (Model: LU700 Series) is a medical imaging device, not an in vitro diagnostic device.
