Ultrasonic diagnostic apparatus

Abstract

Abstract PURPOSE:To attain the reduce actual kernel data, by forming a kernel signal from a hologram signal actually obtained with respect to the arbitrary point of an object in different depth directions while forming the same with respect to other point by linear interpolation. CONSTITUTION:An ultrasonic vibrator 1 is energized by a pulser/receiver 3 to transmit an ultrasonic pulse and receives the reflected wave of the ultrasonic pulse reflected from a reflector 4. A receiving signal is detected by phase detectors 5, 6. A COS hologram signal and a SIN hologram signal obtained are digitalized through A/D converter 9, 10 to be stored in memories 11, 12. A memory 13 uses a depth Z as a parameter to store only kernel data actually calculated corresponding to said depth and a memory 14 stores the kernel data calculated by a computer 17. An operational processing part 14 performs aperture synthesizing operational processing from information respectively imparted from memories 11, 12, 13, 14 to display a re-constituted image on a display device 15.
