US 12,213,839 B2 · Ultrasound diagnostic apparatus and method of controlling ultrasound diagnostic apparatus

Abstract

Provided are an ultrasound diagnostic apparatus capable of appropriately highlighting a blood vessel in an ultrasound image depending on an insertion situation of an insert, and a method of controlling the same. An ultrasound diagnostic apparatus 1 includes a transducer array 2, an image acquisition unit 11 that acquires an ultrasound image, a display device 8 that displays the ultrasound image, an image analysis unit 9 that analyzes the ultrasound image to detect a blood vessel and an insert in the ultrasound image, a highlighting unit 10 that highlights the blood vessel detected by the image analysis unit 9 in displaying the ultrasound image, and an apparatus controller 13 that controls the highlighting unit 10. The apparatus controller 13 performs control such that the highlighting unit 10 changes a form in highlighting the blood vessel depending on a relative positional relationship between the blood vessel and the insert.

Dependent claims

An ultrasound diagnostic apparatus, the ultrasound diagnostic apparatus comprising:

a transducer array;
a processor;
and
a display device,
wherein the processor is configured to:
cause the transducer array to transmit an ultrasound beam toward a subject and receive an ultrasound echo generated inside the subject to acquire an ultrasound image,
display on the display device the acquired ultrasound image,
analyze the acquired ultrasound image to detect a plurality of blood vessels and an insert in the ultrasound image,
specify a distance between each of the detected blood vessels and the insert,
determine whether or not each of the detected blood vessels is at a position reachable by the insert,
specify a closest blood vessel which has the specified distance smaller than a threshold value and is closest to the insert, among the blood vessels determined to be at the position reachable by the insert,
highlight only the closest blood vessel in a second form, and
highlight at least one of the remaining detected blood vessels in a first form different from the second form.
