The document describes standard ultrasound imaging and processing techniques. There is no mention of AI, ML, or related concepts like deep learning, neural networks, or algorithms that learn from data. The image processing described is based on calculating distances and brightness from echo signals, which is typical for traditional ultrasound.
No
The device is an ultrasound system intended for diagnostic imaging and evaluation, not for providing therapeutic treatment.
Yes
Explanation: The "Intended Use / Indications for Use" section states that the system is intended for "ultrasound evaluation" for various clinical applications. The "Device Description" also mentions "diagnosis of cardiovascular diseases" and provides "measurement of anatomical structures and analysis packages, which can offer diagnosticians detailed and useful information," all of which point to its use in diagnosing medical conditions.
No
The device description explicitly states that the system "mainly include the ultrasound equipment and APP software components" and details the function of the "ultrasound equipment" in completing the ultrasonic imaging function. This indicates the presence of hardware beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for "ultrasound evaluation" of various anatomical sites. This is a diagnostic imaging procedure performed on a living patient, not a test performed on a sample taken from the body (which is the definition of an in vitro diagnostic).
- Device Description: The description details an ultrasound system that generates images of internal structures using sound waves. This is consistent with in vivo imaging, not in vitro testing.
- Input Imaging Modality: The input modality is Ultrasonic, which is an in vivo imaging technique.
- Anatomical Site: The listed anatomical sites are all internal structures within a living patient.
- No mention of samples: There is no mention of collecting or analyzing samples (like blood, urine, tissue, etc.), which is a core characteristic of IVDs.
In summary, the Pocket Ultrasound System is a medical imaging device used for in vivo diagnosis, not an in vitro diagnostic device.

The system provides a variety of modes for flexibly selecting, which include B-mode, M-mode, Color-mode, Power-mode, PW-mode, and combined modes (i.e. B/M- mode). Real time image and dynamic changes of tissues, organs or vessels will be showed in the image under B-mode, while coloring blood flow can be seen under Color-mode, PW-mode or Power-mode. M-mode is defined as time motion display of the ultrasound wave along a chosen ultrasound line, so it 's usually applied in diagnosis of cardiovascular diseases.
The system not only provides real-time tissues, organs or blood flow images, but also contains measurement of anatomical structures and analysis packages, which can offer diagnosticians detailed and useful information. The embedded software system along with the touch screen offer users a friendly and convenient graphical interface, which make users be able to easily control the whole system.
Indications for Use
Pocket Ultrasound System(Model:P50.P51.P52.P53.P54.P55.P56) is intended for use by an appropriately trained, qualified physician for ultrasound evaluation. Specific clinical applications and exam types include: Abdominal, Obstetrics, Gynaecoloqy, Small Parts (breast, thyroid, etc), Peripheral Vascular, Urology. This system is suitable for use in hospital and clinical settings.
Technological Principle
The transducers inside the probe are responsible to emitting and receiving ultrasonic waves. When the host pushes pulse with a certain frequency and magnitude onto the transducers, a short burst of ultrasound is emitted from transducers and directed into tissue. Echoes are produced as a result of the interaction of sound with tissue, and some of back to the transducers. Echoes come back is then converted into electric signals by transducers and handed to host for further process.
5
The host is mainly responsible for the following: data processing, in response to user instructions. By receiving the echo pulse transmitting time and timing between the transducer and the echo signal can be calculated by the distance between the structure, form the brightness degree of adjacent image materials. The inherent acoustic impedance difference in the image are different. And through the WIFI transmission and instruction imaging data.
Frequencies vary from about 3MHz for some cardiac, transcranial and deep abdominal applications, to 7MHz for intravascular imaging. Penetration depth and resolution are both associated with the frequency used for imaging, and they are a trade-off as well. The higher frequency is used, better resolution will get, but absorption of the sound energy by tissue also increases which means penetration depth reduces. Proper probes and imaging frequency should be chosen to obtain optimum imaging according to specific application.
Color Doppler imaging takes advantage of the Doppler effect to create a moving image, typically blood flow, of the inside of the body. When the sound bounces off a moving target like a blood vessel, the frequency changes as a result of the Doppler effect. The transducer can detect very subtle frequency changes and record them visually, creating an image which shows where blood is flowing, and in which direction.
Moreover, although the probes need to contact with human body surface in use, the system will not cause any invasive result to or thermal radiation into human body.
