Abstract

PURPOSE:To obtain the tomographic image of a high resolution in a high speed, by using the digital picture processing method. CONSTITUTION:The video signal of the ultrasonic tomographic image obtained by ultrasonic device 4 is input to averaging circuit 11 and picture memory 13 through A/D converter 7 and buffer circuits 8 and 9. The signal from coordinates detecting mechanism 5 is given to write control circuit 10 through coordinates converting circuit 6. Digital picture data read from picture memory 13 is written into buffer circuit 14 and is input to D/A converter 15 as serial digital picture data for every one picture element, and the analogue video signal is input to television display device 16.
