Title:
超音波映像化方法
Document Type and Number:
Japanese Patent JP6959598
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve highly precise imaging of a shape of a boundary between a medium and an imaging object within the medium.SOLUTION: An ultrasonic imaging device 100 comprises a memory 110 memorizing a reception signal received by an ultrasonic receiver 212, a computation unit 120 generating imaging data on the basis of the reception signal, and a display unit 140 displaying a result computed by the computation unit 120. The computation unit 120 has a mesh division unit 122 dividing a medium within an imaging area into meshes, a propagation velocity addition unit 123 determining a mesh propagation velocity on the basis of temperature distribution in the medium, a propagation time calculation unit 124 creating a propagation time table determined for each combination of a position of an ultrasonic transmitter 211 and a position of the ultrasonic receiver 212, an intensity allocation unit 125 allocating a reception intensity contained in the reception signal to each of the meshes corresponding to total propagation time to create an intensity data table, and an intensity combination unit 126 calculating combination intensity by combining the intensity data table.SELECTED DRAWING: Figure 1
