Ultrasound image picking-up device

摘要

There is provided an ultrasound image picking-up device that can correct a positional shift from a reference image before therapy even with insufficient clarity of an ultrasound image. An image processing system includes a position recognition device 1 for recognizing a position to be recognized of an object; a cross sectional image processor 6 that computes cross sectional image data of the object including position information of the position to be recognized; a probe 2 that transmits and receives ultrasound to the object; a ultrasonic image processor 3 that computes a plurality of ultrasound image data based on the ultrasound received by the probe 2; an image selector 7 that selects ultrasound image data including the area to be recognized from the plurality of ultrasound image data; an image processor 4 that aligns, in the area to be recognized, the cross sectional image data with the ultrasound image data including the area to be recognized; and a display 5 that displays a processing result of the image processor.

主权项

1. An ultrasound image picking-up device comprising:
an ultrasound probe configured to transmit ultrasound to an object and to receive ultrasound from said object to which a position recognition device is mounted; an ultrasonic image processor configured to compute an ultrasound cross sectional image based on the ultrasound received by said ultrasound probe; an image data memory configured to store previously acquired volume image data of the object in which position markers are placed in an expected arrangement position of said position recognition device and an expected arrangement position of said ultrasound probe; a data selector configured to select desired slice image data from the volume image data of the object stored in said image data memory; a cross sectional image reconstruction processor configured to reconstruct a cross sectional image corresponding to the computed ultrasound cross sectional image from the slice image data selected by said data selector; a controller configured to link coordinates of the ultrasound cross sectional image, which shows a position of said position recognition device computed based on the ultrasound received by the ultrasound probe arranged in said respective expected arrangement position, with coordinates of the reconstructed cross sectional image, which includes said position markers, based on a correspondence between said position recognition device in said ultrasound cross sectional image and said position markers in said reconstructed cross sectional image; and a display configured to display the ultrasound cross sectional image and the reconstructed cross sectional image whose coordinates are linked in an associated manner, wherein said position recognition device includes at least one chip that includes a transmitter and receiver for an ultrasonic pulse and a signal processor, wherein said transmitter transmits a coded ultrasonic pulse in response to said receiver receiving an ultrasonic pulse from said ultrasound probe in order to actively reflect the position of the position recognition device, and wherein said ultrasonic image processor is further configured to recognize a signal transmitting the position of the position recognition device based on the coded ultrasonic pulse from said position recognition device.
