KS107QN-4B Internal Cavity Scanning Ultrasonic Body Model,KS107QN-4B Phantom.PDF
The KS107QN-4B type internal cavity scanning ultrasonic body model is a human physical model that mimics the ultrasonic propagation characteristics of tissues. It is a testing device composed of Ultrasonically Tissue-Mimicking Material (referred to as TM material) and various test targets embedded within it (including target lines, simulated cysts, simulated stones, simulated tumors), as well as sound windows, shells, and indicative decorative panels.
At the center position of the upper panel of the phantom, there are two scanning holes with an inner diameter of 10mm, which are used to insert the intracavitary probe for ultrasound scanning. They are specifically designed to examine the imaging characteristic parameters of the B-ultrasound imaging device that is equipped with an intracavitary ultrasound probe, including blind zone, lateral (transverse) resolution, axial (longitudinal) resolution, lateral geometric position accuracy, axial geometric position accuracy, and the diameter error of the simulated lesion. The left and right side panels of the phantom have probe hole channels for measuring the withdrawal direction resolution and the geometric position accuracy of the withdrawal direction, with an inner diameter of 10mm. The schematic diagram of the appearance and internal structure of the phantom is shown in Figure 1.
1.The four walls and the bottom are made by assembling pieces of plexiglass. The outer surfaces of the four walls are 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 equipped with a circular hole with a diameter of 36mm, which is sealed with a rubber sheet of 50mm in diameter and 2mm in thickness. This serves as a passage for injecting the maintenance fluid and removing air.
4. The body model is filled with TM material that meets the requirements of national standards as the standard sound transmission medium.
5. On the upper panel of the phantom, there are two central probe access channels with a diameter of φ10mm at 60mm and 120mm from the sound window. These channels are through-hole channels, allowing the probe to be inserted into them for ultrasonic scanning. The left and right side panels of the phantom have probe access channels with an inner diameter of 10mm for measuring the resolution in the retraction direction and the geometric position accuracy of the retraction direction. These channels are through-hole channels running through the left and right side panels, and the internal probe can be inserted through them for scanning.
