Abstract
An image processing system according to an embodiment is an image processing system having a terminal device including a display unit that displays a medical image. The image processing system includes an acquiring unit and a display controller. The acquiring unit acquires a position of the terminal device relative to a predetermined target. The display controller causes the display unit to display a medical image in accordance with the relative position of the terminal device relative to the target acquired by the acquiring unit.
Claims9
An image processing system having a medical image diagnostic apparatus that generates three dimensional image data constituting volume data and a terminal device including a display that displays a stereoscopic image that is configured to be viewed stereoscopically using a parallax image group, the image processing system comprising:
- an image storage device configured to store the volume data generated by the medical image diagnostic apparatus;
- acquiring circuitry configured to acquire a position of the terminal device relative to a subject and a distance between the terminal device and the subject;
- a rendering processor configured to perform rendering processing on the stored volume data so as to generate a parallax image group corresponding to a region of the medical image of the subject that is opposed to the terminal device;
- and
- a display controller configured to cause the display to display the parallax image group generated by the rendering processor, wherein
- the rendering processor determines a viewpoint position and a sight line direction at the time of the rendering processing based on both the position and the distance acquired by the acquiring circuitry and performs the rendering processing on the volume data with the determined viewpoint position and sight line direction.
A terminal device that displays a medical image created by a medical image diagnostic apparatus that generates three dimensional image data constituting volume data and is connected to an image storage device configured to store the volume data generated by the medical image diagnostic apparatus, the terminal device comprising:
- a display configured to display a stereoscopic image that is configured to be viewed stereoscopically using a parallax image group;
- acquiring circuitry configured to acquire a position of the terminal device relative to a subject and a distance between the terminal device and the subject;
- a rendering processor configured to perform rendering processing on the stored volume data so as to generate a parallax image group corresponding to a region of the medical image of the subject that is opposed to the terminal device;
- and
- a display controller configured to cause the display to display the parallax image group generated by the rendering processor, wherein
- the rendering processor determines a viewpoint position and a sight line direction at the time of the rendering processing based on both the position and the distance acquired by the acquiring circuitry and performs the rendering processing on the volume data with the determined viewpoint position and sight line direction.
An image processing method by an image processing system having a medical image diagnostic apparatus that generates three dimensional image data constituting volume data and a terminal device including a display that displays a stereoscopic image that is configured to be viewed stereoscopically using a parallax image group, the image processing method comprising:
- storing the volume data generated by the medical image diagnostic apparatus;
- acquiring a position of the terminal device relative to a predetermined target of a subject and a distance between the terminal device and the subject;
- performing rendering processing on the stored volume data so as to generate a parallax image group corresponding to a region of the medical image of the subject that is opposed to the terminal device;
- and
- causing the display to display the parallax image group generated by the rendering processing, wherein
- the performing determines a viewpoint position and a sight line direction at the time of the rendering processing based on both the position and the distance acquired by the acquiring and performs the rendering processing on the volume data with the determined viewpoint position and sight line direction.
