Product Overview:

         The tissue-mimicking ultrasound phantom (KS107BG) high-frequency ultrasound test phantom is a standard equipment specified by national technical standards and metrological verification regulations, featuring characteristics of a standard device. To align with the guiding principles and technical content of relevant national regulations, and to enhance its richness in connotation, structural robustness, and aesthetic appearance, within the scope of appraisal achievements by the National Bureau of Quality and Technical Supervision, the products from the Institute of Acoustics, Chinese Academy of Sciences have now evolved to the fifth generation, corresponding to the national standard GB10152-2009 and the metrological verification regulation JJG639-98.

Product Features

1. Suitable for performance testing of B-ultrasound instruments operating above 5MHz;
2. Testing items include detection depth, axial and lateral resolution, longitudinal and transverse geometric errors, and can evaluate imaging performance for cystic lesions of different diameters;
