COORDINATE TRANSFORMATION PROCESSING SYSTEM OF ULTRASONIC DIAGNOSTIC APPARATUS

摘要

PURPOSE:To display an ultrasonic image by determining a sampling number and a scan line number in real time corresponding to an address where an echo signal is stored at a low cost concerning a coordinate transformation processing system for an ultrasonic diagnosing apparatus. CONSTITUTION:A TV address computing means 10 receives an image clock TCLK and determines a TV address TVA of a display device to output. An axis distance computing means 20 receives an origin address ORG and a display multiplication PWR in addition to the TV address TVA outputted from the TV address computing means 10 and determines an axis distance from the origin address ORG to output. A sampling number computing means 30 receives the axis distance outputted from the axis distance computing means 20 and determines a sampling number SPN and a sample interpolation coefficient SPM to output. A scan line number computing means 40 receives the axis distance outputted from the axis distance computing means 20 and determines a scan line number SCN and a scan line interpolation coefficient SCM to output.
