Abstract
An ultrasound diagnostic apparatus (1) includes an ultrasound probe (2); an image acquisition unit that generates an ultrasound image by performing transmission and reception of an ultrasound beam with respect to a subject using the ultrasound probe (2); and an initial condition setting unit (25) that sets a basic sound speed value for generating the ultrasound image of a breast of the subject on the basis of a ratio of mammary glands in the breast, which is calculated by analyzing a radiation image in which the breast is imaged, in which the image acquisition unit generates the ultrasound image of the breast using the basic sound speed value.
Claims16
An ultrasound diagnostic apparatus comprising:
- an ultrasound probe;
- a processor configured to
- generate an ultrasound image by performing transmission and reception of an ultrasound beam with respect to a subject using the ultrasound probe,
- acquire tomosynthesis images of a breast of the subject which are captured by performing a tomosynthesis for the breast sandwiched between a first plate and a second plate,
- set a basic sound speed value for generating the ultrasound image of a breast of the subject based on a ratio of mammary glands in the breast, which is calculated by analyzing a radiation image in which the breast is imaged, where the ratio of the mammary glands is represented by a ratio R1 of a volume of the mammary glands in a mammary gland region with respect to a volume of the breast in the mammary gland region, and a ratio R2 of a thickness of a mammary gland layer in the mammary gland region with respect to a breast thickness in the mammary gland region calculated from the tomosynthesis images, where the breast thickness in the mammary gland region is calculated from a lower surface of the first plate and an upper surface of the second plate,
- wherein the processor is further configured to generate the ultrasound image of the breast using the basic sound speed value.
A control method of an ultrasound diagnostic apparatus, the control method comprising:
- acquiring tomosynthesis images of a breast of a subject which are captured by performing a tomosynthesis for the breast sandwiched between a first plate and a second plate,
- setting a basic sound speed value for generating an ultrasound image on the basis of a ratio of mammary glands in a breast of a subject, which is calculated by analyzing a radiation image in which the breast is imaged, where the ratio of the mammary glands is represented by a ratio R1 of a volume of the mammary glands in a mammary gland region with respect to a volume of the breast in the mammary gland region, and a ratio R2 of a thickness of a mammary gland layer in the mammary gland region with respect to a breast thickness in the mammary gland region calculated from the tomosynthesis images, where the breast thickness in the mammary gland region is calculated from a lower surface of the first plate and an upper surface of the second plate;
- and
- generating the ultrasound image of the breast using the basic sound speed value.
