Study on Digitization of X-ray TV System for Ultrasonic Lithotripter
Objective To explore the schemes of digitization of X-ray TV system for ultrasonic lithotripter in order to improve the image resolution of the system.Methods Fixed the resolution testing card to the surface of the image intensifier,and analyzed the pictures on image intensifier with a camera with function of frame integration and a digital single lens reflex camera(DSLR) with function of live-view.Results Both camera and DSLR have lower image resolution in live imaging,whereas static pictures got by DSLR have better resolution.Conclusion Digital imaging devices with functions of real-time dynamic imaging and static pictures of high pixels are ideal for the digitization upgrade of X-ray TV system for ultrasonic lithotripter.
