  • Publication number: 20160066888
    Abstract: An ultrasonic diagnostic apparatus according to an embodiment includes a candidate-position extracting circuitry and a position setting circuitry. The candidate-position extracting circuitry extracts a first position through comparison of a fundamental wave component between a plurality pieces of image data collected by performing ultrasonic scanning on a subject injected with a contrast agent. The candidate-position extracting circuitry also extracts a second position through comparison of a harmonic component between the pieces of image data. The position setting circuitry sets the first position or the second position as a position of a region of interest where predetermined analysis is performed in at least one image data of the pieces of image data.

  • Publication number: 20140236012
    Abstract: Ultrasound diagnosis apparatus is provided which easily recreates test conditions same as the past, comprising scanner, signal processor, display controller, storage, detector, collator, and controller. Scanner scans a subject with ultrasound waves through ultrasound probe. Storage previously stores first relevant information in which operation of the scanner, the signal processor, or the display controller in past test is related to a first relative position which is the relative position of ultrasound probe for the subject in the same past test. Detector detects a second relative position which is the present relative position of ultrasound probe for the subject. Collator collates the first relative position and the second relative position detected by the detector. Controller controls the scanner, the signal processor or the display controller based on the operation related to the first relative position, when the first relative position and the second relative position are matched in collation.

  • Publication number: 20130144168
    Abstract: An ultrasound diagnostic apparatus according to an embodiment includes a memory unit and a converting unit. The memory unit stores therein conversion information, for each ultrasonic probe, converting a coordinate of an attachment position of a position sensor attached to an ultrasonic probe into a coordinate of a predefined position on a surface for transmitting and receiving ultrasonic waves on the ultrasonic probe. When the ultrasonic probe is replaced with another ultrasonic probe, the converting unit acquires conversion information corresponding to the replacing ultrasonic probe and uses the conversion information thus acquired to convert the coordinate of the attachment position of the position sensor attached to the replacing ultrasonic probe into the coordinate of the predefined position.
