KS215T-1 ELASTICITY QA PHANTOM
Tools developed for Ultrasound Elastography systems. These are the only phantoms commercially available for quality assurance of Ultrasound Elastography. The phantoms contain a target of known stiffness relative to the background material and a range of stiffness, diameter and depth.
The composition and structure of the KS215T-1 series ultrasonic elastic tissue phantom are as follows:
(1) The entire series includes 4 independent phantoms with the same background material but different targets;
(2) The side panels and bottom panels of the phantom shell are both 10mm thick organic glass, and the top surface is covered with a composite film acoustic window;
(3) There are two 36mm diameter circular holes on the bottom plate, and the openings are sealed with high-quality rubber for injection and maintenance;
(4) The dimensions of the background material are: length 210mm, width 60mm, height (depth) 110mm;
(5) The target is cylindrical with 6 diameters, namely Φ3, Φ6, Φ9, Φ12, Φ16, and Φ20mm;
(6) The targets are divided into two rows, with the axes located 30mm and 60mm below the acoustic window respectively, and the horizontal interval is 30mm. The horizontal distance between the center point of the starting target and the edge of the phantom is 40mm;
(7) The axis of the cylinder is along the 60mm direction of the background material, perpendicular to the front and rear shell plates, parallel to the surface of the acoustic window, and parallel to each other.
Acoustic-mechanical properties of background and target materials
(1) For background and target materials, the longitudinal wave velocity at 23℃ is (1540±10)m/s;
(2) For background and target materials, the longitudinal wave acoustic attenuation coefficient slope at 23℃ is (0.5±0.05)dB/(cm MHz):
(3) The background materials of all stations in the series are the same, the shear wave velocity at 23℃ is 2.89m/s±5%, and the Young's modulus is 25kPa±10%;
(4) The shear wave velocities of the target materials of each station in the series at 23℃ are 1.63m/s±5%, 2.16m/s±5%, 3.87m/s±5%, 5.16m/s±5%, and
the Young's modulus are
the Young's modulus are
8kPa±10%,
14kPa±10%,
45kPa±10%,
80kPa±10%, respectively.
