An ultrasound dynamic focusing B-scanner which uses the linear array transducer is designed and implemented.
This system can display in real time both B-mode and M-mode images simultaneously.
This paper is composed of system software for controlling the overall system and image processing for real and still images which include histogram equalization technique.
The system software has the modular programming structure and is composed of slave program (1k) which processes the keyboard data by one chip processor (8741 A), master program (18k) which supervises the system by 8085 and interrupt routines which transfer output data.
