Medical image processing device and medical image processing method

摘要

Provided is, for example, a medical image display device which automatically create and display an image suitable for radiographic image interpretation of interosseous tissue or a 3-dimensional image of a vertebral body separated one by one with high precision. A medical image processing device (1) creates a first conversion image (in step (S1)), extracts a first intervertebral disc region from the first conversion image (in step (S2)), and specifies two coordinates (P1, P2) from among the pixels included in the first intervertebral disc region (in step (S3)). Next, the medical image processing device (1) creates a second conversion image (in step (S4)), extracts a second intervertebral disc region (in step (S5)), and specifies two coordinates (Q1, Q2) from the second intervertebral disc region (in step (S6)). Next, the medical image processing device (1) calculates a reference curved surface including at least four feature points of the coordinates (P1, P2, Q1, Q2) on a per intervertebral disc basis and, based on the reference curved surface, creates a display image (in step (S7)), and displays the display image (in step (S8)).

主权项

1. A medical image processing device which creates a display image formed by the pixels of plural cross-sectional images, to be displayed on a display device for radiographic image interpretation of interosseous tissue or bone tissue, comprising:
a conversion image creation unit configured to create a conversion image including the interosseous tissue and plural bone tissues having the interosseous tissue therebetween, on the basis of the plural cross-sectional images; a feature point specification unit configured to execute a process, for each conversion image, of specifying at least two points as feature points by a predetermined specifying condition using at least two conversion images having different conversion curved surfaces showing the position of the pixels that constitute the conversion image; a display image creation unit configured to calculate a reference curved surface for creating the display image on the basis of the feature points and to create the display image on the basis of the reference curved surface; and a display unit configured to display the display image on the display device.
