Abstract
An ultrasonic diagnostic apparatus that can identify the angle of a received ultrasonic beam with respect to the predetermined biopsy path of a biopsy needle. The ultrasonic diagnostic apparatus is characterized by including a received beam forming unit that forms received ultrasonic beams based on the echo signals of ultrasonic waves transmitted into a subject, and a display control unit that displays, in a B-mode image formed based on the received ultrasonic beams, a biopsy guide line in a display mode corresponding to an angle between the beam direction of the received ultrasonic beam and the predetermined biopsy path of a biopsy needle to be inserted into the subject. The biopsy guide line is displayed as, for example, a broken line having a width corresponding to the angle.
Claims8
An ultrasonic diagnostic apparatus, comprising:
- a received beam forming unit that forms a plurality of received ultrasonic beams based on echo signals of ultrasonic waves transmitted into a subject, wherein the plurality of received ultrasonic beams includes a first subset of the plurality of received ultrasonic beams that intersects a predetermined biopsy path of a biopsy needle within a first range of angles and a second subset of the plurality of received ultrasonic beams that intersects the predetermined biopsy path of the biopsy needle within a second range of angles that is different than the first range of angles;
- and
- a display control unit that displays, in an ultrasonic image formed based on the received ultrasonic beams, a biopsy guide line indicating the predetermined biopsy path of the needle, the biopsy guide line being displayed in multiple different display modes at the same time, including a first display mode corresponding to the first subset of the plurality of received ultrasonic beams that interests the predetermined biopsy path within the first range of angles and a second display mode corresponding to the second subset of the plurality of received ultrasonic beams that intersects the predetermined biopsy path within the second range of angles.
A method of controlling an ultrasonic diagnostic apparatus, the method comprising:
- forming a plurality of received ultrasonic beams based on echo signals of ultrasonic waves transmitted into a subject, wherein the plurality of received ultrasonic beams includes a first subset of the plurality of received ultrasonic beams that intersects a predetermined biopsy path of a biopsy needle within a first range of angles and a second subset of the plurality of received ultrasonic beams that interests the predetermined biopsy path of the biopsy needle within a second range of angles that is different than the first range of angles;
- and
- displaying, in an ultrasonic image formed based on the received ultrasonic beams, a biopsy guide line indicating the predetermined biopsy path of the biopsy needle, the biopsy guide line being displayed in multiple different display modes at the same time, including a first display mode corresponding to the first subset of the plurality of received ultrasonic beams that interests the predetermined biopsy path within the first range of angles and a second display mode corresponding to the second subset of the plurality of received ultrasonic beams that intersects the predetermined biopsy path within the second range of angles.
