Imitation organization is B-ultrasound phantom device performance testing standards identified by the Chinese State Administration of Quality and Technical Supervision, the State Drug Administration Associate production, with the current national standard identification procedures JJG639─98 GB10152─1997 and measurement requirements of China, respectively. The model for the KS107BD and KS107BG, former ≤4MHz applicable to the frequency of the B-instrument, which is applicable to the frequency of the B-≥5MHz instrument, covering diagnosis for abdominal, cardiac, small parts, such as linear use, convex array , phased array, machinery sector scan (including ring array) and other probes. Instrument can detect B-blind, probing depth, 10-170mm deep axial and lateral resolution, vertical and horizontal position of geometric precision, and Investigation of tumors, cysts, stones and other typical lesions of image quality. KS205D-1 type of Doppler blood flow phantom and simulation control system for ultrasound and various blood analyzer. Test items include accurate readings of blood flow velocity, blood probing depth, accuracy and sampling cursor orientation recognition capabilities. First, the technical indicators 1.TM material velocity: 1540 ± 10m / s (23 ± 3 ℃) 2.TM material sound attenuation coefficient slope: 0.70 ± 0.05dB / cm / MHz (23 ± 3 ℃) 3. Nylon target wire diameter : 0.3 ± 0.05mm 4. nylon target line position tolerance: ± 0.1mm Second, the detailed parameters of the axial resolution of the target group: each group in the top line of a target located at a depth 10,30,50,70mm, each group The vertical distance from top to bottom center of the target line followed 3,2,1,0.5mm, horizontal distance are 1mm. Lateral resolution of the target group: depth 10,30,50,70mm are located at the center of each group of the target line horizontal distance were 4,3,2,1mm. Blind target group: the lateral distance between centers of adjacent target lines are 10mm, the distance to the sound of the window were 8,7,6,5,4,3,2mm. Longitudinal Target group: Target line containing a total of 12, the center distance between two adjacent lines are 10mm. Transverse target group: Located 40mm depth at center distance between two adjacent lines are 20mm.
