Title:
【発明の名称】超音波診断装置
Document Type and Number:
Japanese Patent JP3315923
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily calculate a frame memory address correction value caused by a processing time to generate a sound scanning line sequence. SOLUTION: A test signal generating part 10 and a time phase difference detecting circuit 11 are mounted on this ultrasonic diagnostic equipment. Test signals generated at the test signal generating part 10 are transmitted to an ultrasonic probe 1. After signal-processing the signal received via a receiving part 3 from the ultrasonic probe 1, a sound scanning line data sequence S1 is generated at a digital scan convertor(DSC) 6. A transmit start signal S2 of the test signals and a sound scanning sequence S1 are compared at the time phase difference detecting circuit 11, signal processing times at the receiving part 3, an image processing part 4, an A/D convertor 5, and the DSC 6 are calculated to store them as correction addresses into a correction data memory 8. Sound scanning line data shifted by the correction addresses are written into a write starting address in a frame memory 7 as sound scanning line data corresponding to true diagnostic image display start position.
