Ultrasound image picking-up device

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.
