WebIn ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). WebApr 5, 2024 · Clinical ultrasound’s maximum utility as a diagnostic tool rests on understanding and manipulating multiple physics principles. The knowledge of ultrasound wave emission, interaction with fluid, tissue, various densities, wave receipt, and machine data processing are integral to ultrasound’s function. Ultrasound machines rely upon … WebTurning the far field gain dial will adjust the image gain in the bottom half of the image. Manufacturers like GE, Siemens, and Terason use up to 10 separate, depth specific, sliders to modify the image gain. TGC sliders are used to adjust the gain in specific areas of the image (near-, mid-, and far-field). informatica安装包
