ULTRASONIC DIAGNOSIS APPARATUS

摘要

PURPOSE:To make it possible to scan the front region of an ultrasonic probe over a wide region and to make an image with high resolution by providing an ultrasonic oscillator array, an ultrasonic probe, a treating device based on an opening synthesis system and an image constituting device. CONSTITUTION:A receiving signal transferred to a receiving circuit part 8 from a microultrasonic oscillator is treated by amplification in the receiving circuit part 8 and is converted to a digital value in an A/D convertor 9 and is stored in a memory 10. This movement is repeated until all the necessary data for making an image are stored. The received signal data stored in the memory 10 are red out properly by means of a signal treating part 11 and such treatments as retardation, weighing and addition are treated on them by means of an opening synthesis system for realizing high resolution and a necessary scanning range to make image data. Synthesized image data are transferred to an image constituting part 12 and are made into video signals and are displayed on a CRT 14. A series of these movements is controlled by a control part 13 contg. a time base.
