KS107BD(L) Ultrasound Phantom,KS107BD(L) QA phantom
Mode：KS107BD(L)
Type:QA-Phantom
Contact： ken@hkmedqc.com
KS107BD(L) Ultrasound Phantom is suitable for basic image parameter detection of ultrasonic diagnostic instruments and is applicable to low-frequency B-ultrasound instruments below 5MHz. It is an extension of the KS107BD model in depth direction, and the detection depth is increased from 190mm of the BD model to 250mm. The detection items include blind area, detection depth, axial (longitudinal) and lateral (transverse) resolution, longitudinal and transverse geometric errors, and can examine the imaging of typical lesions such as cysts, tumors, and stones.
The KS107BD(L) ultrasonic phantom complies with the requirements of the current Chinese national standards GB10152─2009, YY0767-2009 and the metrological verification regulations JJG639─2005 and JJF1438-2013. The acoustic parameters of the phantom have been tested by the Acoustic Metrology Test Station of the Chinese Academy of Sciences, which is accredited by the National Certification and Accreditation Administration, and can be accompanied by the metrological test certificate of the station.
Technical Specifications of KS107BD(L) Phantom :
1. TM material sound 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 wire position tolerance: ±0.1mm
Eight groups of nylon wire targets are embedded in the TM material. They include:
(1) Axial resolution target group. Its lateral branches are 30, 50, 70, 120 and 160mm away from the sound window respectively. The horizontal distances between the centers of two adjacent target wires in groups A1 and A2 are 1, 5, 4, 3, 2mm respectively, and those in groups A3-A5 are 5, 4, 3, 2mm respectively. The vertical distances between the centers of two adjacent target wires in the longitudinal branches are 4, 3, 2, 1mm respectively.
(2) Blind area target group. The horizontal spacing between the centers of adjacent target lines is 10 mm, and the distances to the acoustic window are 10, 9, 8, 7, 6, 5, 4, and 3 mm, respectively.
(3) Longitudinal target group. There are 25 target lines in total, and the distance between the centers of two adjacent lines is 10 mm.
(4) Horizontal target group. There are 7 target lines in total, and the distance between the centers of two adjacent lines is 20 mm.
Simulated lesions
(1) Tumor-like structure, located between 70 and 80 mm in depth, cylindrical, 10 mm in diameter, and the axis of the cylinder is parallel to the target line.
(2) Simulated cysts and stones. The simulated cysts are cylindrical, 10 mm in diameter, located between 70 and 80 mm in depth, and the axis is parallel to the target line. The simulated stones are irregular in shape, located in the middle of the cyst, and the maximum size is about 4-6 mm.
(3) Simulated cyst structure, cylindrical, 6 mm in diameter, and the axis of the cylinder is parallel to the target line, located between 47 and 53 mm in depth.
