Title:
ULTRASOUND DIAGNOSIS APPARATUS AND MEDICAL INFORMATION PROCESSING PROGRAM
Document Type and Number:
Japanese Patent JP2019195447
Kind Code:
A
Abstract:
To maintain accuracy of alignment and improve efficiency of examination.SOLUTION: An ultrasound diagnostic apparatus comprises a control unit, an image data generation unit, a reconstruction unit, and a similarity calculation unit. The control unit causes two-dimensional ultrasound scan to be executed on a subject by way of an ultrasound probe which has a position sensor mounted thereon. The image data generation unit generates two-dimensional ultrasound image data on the basis of echo data collected by the two-dimensional ultrasound scan. The reconstruction unit reconstructs two-dimensional medical image data from pre-acquired three-dimensional medical image data of the subject on the basis of the position information of the two-dimensional ultrasound image data in a first coordinate space identified from output of the position sensor, and of a correlation between a second coordinate space to which the three-dimensional medical image data belongs and the first coordinate space. The similarity calculation unit calculates similarity between the two-dimensional ultrasound image data and the two-dimensional medical image data each time when a predetermined condition is satisfied.SELECTED DRAWING: Figure 1
