Abstract:Siemens digital subtraction angiography (DSA) needs to redesign the interface circuit of high voltage trigger pulse
conversion after replacing the digital subtraction image workstation. In this study, we focused on the principle of pulse
waveform conversion, provided a detailed scheme for the design of the interface circuit, and designed the corresponding
hardware interface circuit. This design further solved the waveform conversion problem of high voltage control signal, ensured
the synchronization of the control signal, and realized the control of normal exposure and image acquisition and processing by
the new DSA system. We emphasized the design, analysis and implementation of high voltage trigger pulse conversion circuit,
which was one of the interfaces between image workstation and high voltage part. The design provides a good reference for the
combination of theoretical learning and practical ability of biomedical engineering students.
