Ultrasound diagnostic apparatus and control method of ultrasound diagnostic apparatus
An ultrasound diagnostic apparatus and a control method of an ultrasound diagnostic apparatus that enable a user to easily use information stored in a tag of an ultrasound image are provided. An ultrasound diagnostic apparatus ( 1 ) displays an ultrasound image on which a breast schema image showing a position of an ultrasound probe ( 2 ) in imaging is superimposed, and includes a text information conversion unit ( 17 ) that converts the position of the ultrasound probe ( 2 ) plotted on the breast schema image into text information, and a text information storage unit ( 18 ) that stores the text information converted by the text information conversion unit ( 17 ) in a tag attached to the ultrasound image.
1 . An ultrasound diagnostic apparatus that displays an ultrasound image on which a breast schema image showing a position of an ultrasound probe in imaging is superimposed, the apparatus comprising:
an external communication circuit configured to receive, from an external apparatus, the ultrasound image on which the breast schema image is superimposed; and
a processor configured to
convert the position of the ultrasound probe plotted on the breast schema image into text information representing one of a plurality of regions by which a breast of a subject is divided, by:
extracting, from the breast schema image superimposed on the ultrasound image received via the external communication circuit, a probe mark representing the position of the ultrasound probe by calculating a difference between the breast schema image and a template of a breast schema,
calculating coordinates of a center of the probe mark with reference to a center point of the template, and
converting a region to which the coordinates of the center of the probe mark belong among among the plurality of divided regions of the breast into the text information as the position of the ultrasound probe; and
store the converted text information in a tag of the Digital Imaging and Communications in Medicine (DICOM) standard attached to the ultrasound image.
2 . A control method of an ultrasound diagnostic apparatus that displays an ultrasound image on which a breast schema image showing a position of an ultrasound probe in imaging is superimposed, the method comprising:
receiving, from an external apparatus, the ultrasound image on which the breast schema image is superimposed;
converting the position of the ultrasound probe plotted on the breast schema image into text information representing one of a plurality of regions by which a breast of a subject is divided, by:
extracting, from the breast schema image superimposed on the ultrasound image received via the external communication circuit, a probe mark representing the position of the ultrasound probe by calculating a difference between the breast schema image and a template of a breast schema,
calculating coordinates of a center of the probe mark with reference to a center point of the template, and
converting a region to which the coordinates of the center of the probe mark belong among the plurality of divided regions of the breast into the text information as the position of the ultrasound probe; and
storing the converted text information in a tag of the Digital Imaging and Communications in Medicine (DICOM) standard attached to the ultrasound image.
