No
The document describes standard ultrasound image processing and data handling without mentioning AI or ML algorithms.
No.
The device is described as an ultrasound imaging system for clinical diagnosis, which involves creating images for diagnostic purposes rather than directly providing therapy.
Yes
The device is intended for clinical diagnosis of various conditions related to small organs (breast) and peripheral vessels, which falls under the definition of a diagnostic device.
No
The device description explicitly states it consists of two major components: a USB box (hardware containing microprocessor, memory, amplifiers, power supply) and a transducer (hardware). While software is mentioned as running on a connected PC, the core device includes significant hardware components.
Based on the provided text, the NTU-USB ultrasound USB box is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens taken from the human body. The text clearly states that the NTU-USB ultrasound USB box is used for "real-time anatomical imaging" and "blood flow measurements" directly on the patient's body (Small Organs/Parts like the Breast and Peripheral Vascular).
- The intended use is for clinical diagnosis through imaging. The description focuses on generating ultrasound images and performing measurements based on those images, not on analyzing biological samples.
Therefore, the NTU-USB ultrasound USB box falls under the category of medical imaging devices, not in vitro diagnostic devices.
N/A
Intended Use / Indications for Use
The NTU-USB ultrasound USB box is a general ultrasound imaging system intended for use by a qualified physician or sonographer for clinical diagnosis. Specific clinical applications and exam types include:
- Small Organ (Breast)
- Peripheral Vessel

Device Description
The NTU-USB Ultrasound USB box is a standalone ultrasound system which can perform real-time anatomical imaging of Small Organs/Parts (e.g. Breast) and blood flow measurements of Peripheral Vascular. Users include ultrasound imaging technicians (sonographers) and physicians. The NTU-USB Ultrasound USB box may be used in a hospital (e.g. imaging laboratory, emergency room, patient bedside, operating room), medical clinic, physician's office or a mobile imaging center.
The NTU-USB Ultrasound USB box consists of two major components: 1) USB box; and, 2) Transducer. The USB box housed the microprocessor, memory, amplifiers and a power supply for the microprocessor. The USB box performs the calculations involved in processing the data to produce the displayed ultrasound image.
The USB box is designed to connect with a Windows x86platform PC/laptop (not included in this product) and a compatible linear transducer. It receives command and display on the UI of the PC/laptop and following sends electrical currents to and receives electrical pulses from the compatible transducer.
The system provides qualified physicians with a friendly workflow and sufficient image quality for the following applications:
B (2D) mode, ColorDoppler (CD), Pulsed Wave Doppler (PW) mode
Available with the system is a Linear array transducer allowing for many clinical applications. Accessories include an AC adaptor and a USB 3.0 cable. Case studies can be stored to USB memory stick, DVD, and other industry standard archiving devices using the connected PC/laptop.
The NTU-USB ultrasound USB Box contain the hardware and software which collect and pro-process 'rough' data and send it via USB 3.0 connection to a Windows based PC. The main application software is NTU-USB SW running on the PC, it is receiving data, processing and showing image/data on the screen. The main user interface shows an ultrasound image, controls and drop-out menus. The ultrasound images and calculated/measured data can be stored in memory.
