Paper Abstract

We developed a digital data recorder (DDR) for realtime recording for use with a realtime digital cardio angiography system (DCA). The DDR can record/reproduce data at a rate of 8.7 MB/s. Also it can record data continuously for 20 min on a 1/2-inch high HC video cassette tape (data of 10.5 GB in total). Namely, it can realtime record images at a rate of 30 images in 512)(512 matrix/s or 7.5 images in 1024)(1024 matrix/s. Static images can be recorded in the majority mode with an improved reliability. Since the DDR can record data using commercially-available cassette tapes, the running costs are very low. Through clinical evaluation, We have a belief that the DCA using the DDR will take the place of the cine camera radiographic system.
