Device Description The proposed eHertz Functional Series Diagnostic Ultrasound System (eHertz C, eHertz E, eHertz R, eHertz S) are portable, laptop-style ultrasound imaging system used to perform diagnostic general purpose ultrasound imaging studies. The system contains a scan converter and can be coupled to a variety of linear, convex, and phased array transducers to produce images, which are displayed on {5} eSonic 510(k) Summary- K250228 a LED monitor. The eHertz Functional Series is a Track 3 diagnostic ultrasound system. The system includes electronics for transmit and receive of ultrasound data, ultrasound signal processing, software computing, hardware for image storage. The eHertz Functional Series Diagnostic Ultrasound System's software features include mFlow, eSRI, eTuner, eTissue, Steer angle, and 2B/4B, etc. - mFlow is a micro blood flow imaging technique. This mode is suitable for higher resolution display of blood flow near the surface of the body compared to C mode. - eSRI is a post-processing of images to reduce speckles, noise, and enhance image edge without affecting the frame rate. Image quality can be optimized. - eTuner: Parameters such as B-mode image gain are automatically adjusted to optimize images according to depth and tissue attenuation. - eTissue: The receiving parameters related to the assumed acoustic speed of ultrasound propagating in the human body can be adjusted. Adjust the acoustic speed parameter to match the tissue type, thereby improving spatial and temporal resolution. - Steer angle: This function is used to adjust the scan deflection angle. - 2B/4B: It can switch the display layout of images and support dual or four display. When displaying multiple images, only one image is active, while the others are all frozen images. ## 5.
