1. Simulated minimum resolution size of arterial blood vessels and motion artifact detection module
Contrast agent concentration: 150mg/mL, 300mg/mL, one piece each, three simulated blood vessels, with a width and thickness of 1.0, 2.0, and 4.0mm, respectively. Each tube has simulated arterial stenosis and aneurysm,
The width is 1/4, 1/2, and 3/4 of the width of a single artery, and the module size is 300 * 150 * 25.4mm, as shown in the figure
2. Low contrast iodine line pair test plug-in
There are three groups of iodine contrast agent filled test lines in the module, each consisting of four lines with different diameters of 0.5, 1.0, 2.0, and 4.0mm, respectively.
The concentrations of iodine contrast agents in the three line groups were 2.5, 5.0, and 10.0mg/cc, respectively. The module size is 200 * 150 * 25.4mm, as shown in the figure
3. Image Linearity Test Plugin
There are six 19mm test areas distributed in a circular pattern on the test board, with different iodine thicknesses and concentrations of 20.0, 10.0, 4.0, 2.0, 1.0, and 0.5mg/cm3, respectively. The dimensions are 200 * 150 * 25.4mm, as shown in the figure.
4. Bone simulation test block
PTFE strips containing three types of simulated bones, with a width of 25mm and thicknesses of 5mm, 10mm, and 15mm, respectively. The size is 200 * 200 * 25.4mm, as shown in the figure.
5. High contrast resolution test plugin
To be used in conjunction with the wire pair card, a groove is opened on the test board for placing the wire pair card. The wire pairs are (0.6~5.0) Lp/mm, with a total of 20 pairs and a lead foil thickness of 0.05 mm. It can support horizontal, vertical, and 45 degree rotation positioning of line to card, and the size of the line to card is 50 * 50mm. The module size is 200 * 150 * 25.4mm.
6. Slot block (mold base)
The mold has an opening that can be used to fix and position other modules, and to place different modules for different parameter measurements. Module outer size: 200 * 200 * 76.5mm, slot size: 200 * 150 * 25.4mm
7. Distribution board
Made of aluminum, filled with 3.2mm sized holes, size: 200 * 200 * 1.5mm
