The range of contrasts, resolution, linearity, consistency, amplifier dynamics, matching accuracy and dilution effectiveness can be checked and can be quantified to measure high and low contrast spatial resolutionI don't know。
The results are easy to understand. Wek-dsa test module is consistent with aapm report no. 15, iec 61223-3-1, ce certification。The design of a unique walker allows for automatic module mitigation, without the need for operator pressure, and manual operating blocks are reduced by walking in the irradiation field, thus effectively reducing the operator's exposure to radiation。
Different modules achieve the testing of different indicators。
