Embodiment approach 1

[0065] figure 1 It is a block diagram showing the configuration of the ultrasonic diagnostic apparatus 20 according to the present embodiment. The ultrasonic diagnostic apparatus 20 includes an ultrasonic transmitter / receiver 21 , an ultrasonic image generator 22 , a storage unit 23 , an edge detection unit 24 , a component identification unit 25 , a pathology analysis unit 26 , a control unit 27 , and a screen generator 28 . As an image processing circuit, the ultrasonic image generation unit 22 , the storage unit 23 , the edge detection unit 24 , and the component element identification unit 25 are constituted by circuits of one block. In addition, the ultrasonic transmitter-receiver 21 , the pathological condition analysis unit 26 , the control unit 27 , and the screen generator 28 are configured as circuits other than the image processing circuit. These may also be configured as the internal structure of the image processing circuit as needed. The ultrasonic probe 11 , t...

Abstract

An ultrasound diagnostic device including a component specifier. Assume a first direction is a depth direction substantially perpendicular to a surface of a subject, a second direction is a direction orthogonal to the first direction, a first pixel is a pixel at a pixel location N in the second direction, a second pixel is a pixel at a pixel location N+1 in the second direction, and N is a positive integer. The component specifier detects one or more feature lines from the ultrasound image by repeatedly, while incrementing N, linking the first pixel with the second pixel when luminance of the second pixel is high and the second pixel is in close proximity to the first pixel, and specifies which of the one or more feature lines indicates a boundary between components, based on an order in the first direction of the one or more feature lines.

Description

[0001] Japanese Patent Application No. 2013-169527 filed on August 19, 2013, Japanese Patent Application No. 2013-171033 filed on August 21, 2013, and Japanese Patent Application No. 2014-160638 filed on August 6, 2014 The disclosure contents of the claims, the specification, the drawings, and the abstract included in the document are incorporated herein by reference in their entirety. technical field [0002] The present invention relates to an ultrasonic diagnostic apparatus, an ultrasonic image analysis method, and a program for performing ultrasonic diagnosis by bringing an ultrasonic probe for transmitting and receiving ultrasonic waves into contact with the body surface of a subject, especially limb joints. Background technique [0003] In recent years, it has become more and more common to use ultrasonic diagnostic apparatuses for the evaluation of disease activity of arthritis including joint rheumatism. In the evaluation of disease activity, B-mode images and power ...
