The ultrasound phantom KS107BG is applicable to the performance testing and quality assurance of the ultrasound instrument with operating frequency between 5MHz-10MHz.
A clinical diagnose is usually made based on the ultrasonic scanning information, which is revealed mainly from the ultrasonography. Thus the ultrasonic image quality of the B-mode ultrasound instrument is regarded as an important factor for judging the validity of the ultrasonograpic diagnosis. Following the international conventions, the technical indicators to assess B -mode ultrasonic image quality (i.e., performance) include dead zone, depth of penetration, axial resolution, horizontal resolution, beam slice thickness, contrast resolution and caliper accuracy, etc. The only way to assess those factor for B-mode ultrasonic instrument is Tissue Mimicking(TM) Ultrasound Phantom. Ultrasound Phantom is a test object containing Tissue Mimicking (TM) material that simulates the acoustic and physical properties of human tissue. A series of test targets were embedded in the TM material for testing and imaging purpose. An acoustic window was place at the surface of the TM material for simulation of the skin of epithelial tissue. Our products, the Model KS107BD/G, was developed to provide a reliable tool for quality control checks on most ultrasound diagnosis system. They followed the requirements of Chinese National Standards GB10152-2009 and the national metrology verification regulation JJG639-98(2005).
