Embodiment Construction

[0029] Hereinafter, the present invention will be described in more detail with reference to the drawings. An ultrasonic diagnostic system according to an embodiment of the present invention irradiates a subject such as a human body with ultrasonic waves, and creates a tomographic image (ultrasonic image) using received reflected wave signals. A doctor confirms the generated tomographic image and makes a diagnosis.

[0030] like figure 1 As shown, the ultrasonic diagnostic system 10 of this embodiment includes a ring array R, a switch circuit 110 , a transceiver circuit 120 , an arithmetic unit 130 , and an image display unit 140 .

[0031] The ring array R is a ring-shaped vibrator preferably having a diameter of 80 to 500 mm and more preferably a diameter of 100 to 300 mm, which is composed of a plurality of vibrators. In addition, the circular array R can also adopt a variable diameter structure. In this embodiment, as an example, a ring-shaped vibrator in which four con...

Abstract

The present invention provides an ultrasonic diagnostic system that generates accurate and clear ultrasonic images. This ultrasonic diagnostic system includes: a plurality of elements that are disposed around a subject and transmit and / or receive ultrasonic waves; a data collection unit that, while switching the elements transmitting the ultrasonic waves, collects measurement data regarding reflected ultrasonic waves reflected from the subject via at least some of the plurality of elements; and a first learning device that outputs a tomographic image of the subject from the input measurement data by carrying out learning using learning data containing a subject model expressed by the distribution of acoustic characteristics, and simulation measurement data which was obtained by transmitting ultrasonic waves while switching the elements in a simulation space that simulates the size and arrangement of the plurality of elements, and receiving reflected ultrasonic waves from the subject model, such waves received by at least some of the plurality of elements.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic system for generating a tomographic image of a subject by irradiating ultrasonic waves. Background technique [0002] A non-invasive diagnostic system based on ultrasound is widely used in the medical field as a technique for diagnosing information in a subject's body because it does not require a surgical operation for directly incising and observing a living body. [0003] Ultrasound CT (Computed Tomography: computerized tomography), which is one method of ultrasonic diagnosis, is a technique of irradiating ultrasonic waves to a subject and creating a tomographic image of the subject using reflected ultrasonic waves and transmitted ultrasonic waves. usefulness for the detection of breast cancer. Ultrasonic CT creates tomographic images using, for example, a circular array transducer in which a plurality of elements for transmitting and receiving ultrasonic waves are arranged in a ring shape. ...
