  • Patent number: 11103215
    Abstract: According to one embodiment, an ultrasound image diagnosis apparatus includes a boundary detection unit, a measurement unit, and a display control unit. The boundary detection unit detects the boundary of a structure in a subject based on volume data generated from a reflected signal of ultrasound waves transmitted toward inside of the subject. The measurement unit measures the size of the structure based on the boundary detected by the boundary detection unit. The display control unit displays the cross section of the structure according to a definition that is set in the advance and related to the size of the structure measured by the measurement unit.

  • 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.
