DSA-V8 wireless DSA performance testing phantom

DSA performance testing phantoms are used for quality assurance of digital subtraction angiography equipment and can detect dynamic range, contrast sensitivity, nonlinear attenuation compensation (logarithmic error) and artifacts (subtraction performance response).

Technical parameters:

1. Wireless remote control of the DSA phantom can simulate blood flow and automatically reset the blood vessel plate outside the shielded room.

2. The main body of the phantom: 225mmx180mx57m PMMA attenuation layer with 10mm moving slot

3. Simulated vascular plate: 150*163*9.5mm, moving distance 10mm

4. Simulated blood vessels: 4 simulated blood vessels (aluminum, purity 99.9%), thicknesses are 0.05mm, 0.1mm, 0.2mm, 0.4mm (5-10 mg/ml)

5. Dynamic copper ladder: 8 steps (perpendicular to the direction of the aluminum strip), of which the thickness range of the 7th step is 0.2-1.4mm

6. Slider position indicator: The "A" position is a yellow indicator light, and the "B" position is a blue indicator light, used to indicate the current position of the simulated vascular plate.

7. Pattern structure: integrated mechanism, no external motion mechanism, easy to operate and carry

8. Power supply: 9V rechargeable battery power supply

9. Wireless control: 15m effective acceptance range, can penetrate the metal shielding of the shielded room.
