Problems solved by technology

However, to grasp the three-dimensional structure of the subject from two X-ray images from different irradiation angles requires the operator's anatomical knowledge and proficiency
[0005] The digital tomosynthesis device that digitizes the X-ray tomography device is a technology that synthesizes tomographic images in the subject with low radiation. It also moves the X-ray source mechanically, so there are dynamics that are not suitable for fast-moving organs or joints. observation problem

[0028] Below, refer to Figure 1 to Figure 13 Embodiments for carrying out the present invention will be described in detail. figure 1 It is a structural block diagram of the X-ray diagnostic apparatus 1 in 1st Embodiment. figure 1 The shown structural block diagram of the X-ray diagnostic apparatus 1 is a structural diagram viewed from above, and has a multi-output X-ray source unit 10, an X-ray detection unit 11, a timing control unit 12, an image acquisition unit 13, a deformation correction unit 14, an image recording unit 15 and stereoscopic image display unit 16 .

[0029] The multi-output X-ray source unit 10 is provided with a plurality of small X-ray sources, and can output X-rays from a plurality of different positions as indicated by dotted arrows. A plurality of X-rays emitted from the multi-output X-ray source unit 10 at different angles pass through the subject P and enter the X-ray detection unit 11 .

[0048] In this embodiment, in addition to the first embodiment, an embodiment in which a stereoscopic perspective image can be observed even when the observer moves his line of sight in the elevation direction will be described. Figure 8 It is a block diagram of the structure of the X-ray diagnostic apparatus of this embodiment. exist figure 1 On the basis of , a camera unit 81 , a face tracking unit 82 and an interpolation unit 83 are added.

[0049] The camera unit 81 is preferably installed above and below the stereoscopic image display unit 16 in order to capture the observation position (line-of-sight position) of the observer. By installing them at symmetrical positions with respect to the stereoscopic image display unit 16 , it is possible to calculate the angle of the line of sight with respect to the center. The image sensor used in the camera unit 81 is usually a sensor capable of capturing visible light, but an infrared image sensor or the like may also be used w...

[0062] In the first and second embodiments, an example in which nine transmission images having different parallaxes are input to the stereoscopic image display unit 16 has been described. However, in order to obtain a stereoscopic perspective image, it is only necessary that two transmission images corresponding to the left and right eyes follow the movement of the line of sight and be correctly input to the observer. As in the first and second embodiments, the resolution of the liquid crystal monitor of the stereoscopic image display unit 16 decreases as the number of displayed transmission images with different parallaxes increases and corresponding pixels are used. Therefore, misinterpretation and the like may easily occur.

[0063] In the present embodiment, two transmission images corresponding to the left and right eyes are used in order to realize higher resolution of medical images and further improvement of moving image performance. Furthermore, since the unnecessar...

Abstract

To provide an X-ray diagnostic apparatus capable of providing a stereoscopic perspective image in the form of a video image while reducing exposure dose. An X-ray diagnosis apparatus according to an embodiment includes: a main row X-ray source group including a plurality of X-ray sources; an X-ray detection section disposed opposite to the X-ray sources; a timing controller that controls a switching timing of the X-ray sources and an X-ray generation position; an image acquisition section that acquires output image data from the X-ray detection section in synchronization with the switching timing; and a stereoscopic image display section that displays the output image data as a plurality of images having different disparities.

Description

technical field [0001] Embodiments of the present invention relate to an X-ray diagnostic apparatus capable of stereoscopic viewing. Background technique [0002] Examples of diagnostic devices that stereoscopically observe the inside of a subject by utilizing the fact that X-rays penetrate the human body include X-ray CT devices, X-ray diagnostic devices for circulators, and digital tomosynthesis devices. [0003] The X-ray CT device can obtain a complete three-dimensional structure by reconstructing various tomographic images of the subject. However, since it has a rotating mechanism for scanning, it is not good at imaging fast-moving organs such as the heart. Therefore, the scanning speed was increased by increasing the number of columns of detectors and increasing the rotation speed, but the imaging range was still narrow, and moving images at 30 frames per second could not be obtained. The current situation is that even a device with a fast rotation speed can only obt...
