KS107QN-4A Intracavity Scanning Ultrasound Phantom,KS107QN-4A Vascular Ultrasound pahntom is a human body physical model that mimics tissue in terms of ultrasound propagation characteristics. It is a test device composed of Ultrasonically Tissue-Mimicking Material (TM material) and a variety of test targets embedded therein (including target lines, simulated cysts, simulated stones, simulated tumors), as well as acoustic windows, shells, and indicative decorative panels. Two intracavitary probe scanning through holes with an inner diameter of 3mm are opened at the center of the upper panel of the phantom to insert the intracavitary probe for ultrasonic scanning. It is specially used to examine the imaging characteristic parameters of the B-ultrasound imaging device equipped with the intracavitary ultrasound probe, including blind area, lateral (transverse) resolution, axial (longitudinal) resolution, lateral geometric position accuracy, axial geometric position accuracy, and diameter error of the simulated lesion. The left and right side panels of the phantom have exploration hole channels for measuring the resolution and geometric position accuracy in the withdrawal direction, with an inner diameter of 3mm.
KS107QN-4A has a 3mm Ф intracavity probe scanning hole,
1. The four walls and the bottom are made of organic glass, and the outer surface of the four walls is covered with plastic film panels for indication and decoration;
2. The overall dimensions are 210mm (length) × 140mm (width) × 66mm (height);
3. The bottom plate is opened with a circular hole with a diameter of 36mm and sealed with a rubber sheet with a diameter of 50mm and a thickness of 2mm, which serves as a channel for injecting maintenance fluid and degassing;
4. The phantom is filled with TM material that meets the requirements of national standards as a standard sound transmission medium.
5. The upper panel of the phantom has a center opening of φ3mm diameter intracavitary probe exploration hole channels at 60mm and 120mm away from the sound window. The channel is a through hole channel, and the probe can be inserted into the hole for ultrasonic scanning. The left and right side panels of the phantom have exploration hole channels with an inner diameter of 3mm for measuring the resolution of the withdrawal direction and the geometric position accuracy of the withdrawal direction. This channel runs through the left and right panels, and the intracavitary probe can be inserted from the left and right side panels for scanning.

The lateral spacing between the centers of two adjacent target lines (the chord length between the two target lines) is 3, 2, 1, and 0.5 mm, respectively.
The two adjacent target lines in the axial branch of this target group are on the radius with the center of the central detection hole as the center of the circle, and the difference between the center of the adjacent target line and the center radius of the detection hole is 0.5, 1, 2, and 3 mm, respectively.
