  • Publication number: 20210353258
    Abstract: According to one embodiment, an ultrasound diagnostic apparatus can be connected with an ultrasound probe including a plurality of elements adapted to transmit ultrasound signals and to receive reflected wave signals from a subject or from the air. The ultrasound diagnostic apparatus includes processing circuitry. The processing circuitry diagnoses states of the elements based on a feature value of the reflected wave signal. The processing circuitry also prepares, based on the states, deterioration degree information indicative of the deterioration degrees of the elements. The processing circuitry superimposes the deterioration degree information onto an ultrasound image of the subject and causes a display to display a resultant image.

  • Patent number: 10893849
    Abstract: According to one embodiment, an ultrasound image diagnosis apparatus includes a display and a control circuit. The display is configured to display an ultrasound image generated based on an echo signal of ultrasound waves transmitted to a site to be diagnosed. The control circuit is configured to measure a measurement target on the ultrasound image of the site to be diagnosed displayed on the display. The control circuit performs a definition function to define the distance between a caliper used to measure the measurement target and a guide used to arrange the caliper at the position of the measurement target, a display control function to control the display of the caliper and the guide arranged to be separated by the distance defined such that the caliper and the guide are integrally movable on the ultrasound image, and a measurement function to measure the measurement target using the caliper.

  • 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.
