WEK-DSA Test Phantom: This DSA performance test phantom is designed to evaluate the digital functions of DSA systems. Featuring a novel design, the phantom significantly enhances the quality of subtraction angiography.
1. Product Introduction
1. Product Introduction
The WEK-DSA phantom is used to evaluate the digital function of the DSA system; the phantom adopts a new
design, which greatly improves the quality of subtraction angiography. Contrast range, resolution, linearity, consistency,
amplifier dynamic range, matching accuracy and subtraction effectiveness can be checked, and quantitative measurements
can be made to measure high and low contrast spatial resolution. Easy-to-understand results are provided.
WEK-DSA phantom complies with the Association of Physicists in Medicine (AAPM) Report No. 15,
IEC61223-3-1, and CE certification. WEK-DSA phantom is a Digital Subtraction Angiography QA Test Phantom
The uniquely designed traversing mechanism enables an automatic module subtraction function; this eliminates the need for an operator to manually manipulate the block within the radiation field to perform subtraction, thereby effectively minimizing the operator's exposure to radiation.
Different modules are utilized to assess specific performance parameters.
WEK-DSA Test Phantom — DSA Performance Evaluation Phantom: Technical Specifications
WEK-DSA Test Phantom Module for Assessing Minimum Arterial Vessel Resolution and Motion Artifacts
Contrast Agent Concentration: Includes two blocks—one at 150 mg/mL and one at 300 mg/mL. Features three simulated vessels with widths and thicknesses of 1.0 mm, 2.0 mm, and 4.0 mm, respectively. Each vessel incorporates simulated arterial stenoses and aneurysms with widths corresponding to 1/4, 1/2, and 3/4 of the respective vessel's diameter. Module dimensions: 300 × 150 × 25 mm.
