Abstract
In an X-ray diagnostic apparatus, a volume 3D image in which a desired blood vessel center line has been extracted is stored in a CT 3D image storage unit, and an X-ray two-dimensional image updated in real time is stored in an X-ray 2D image storage unit. The three-dimensional image is aligned with the X-ray two-dimensional image in an alignment unit. Further, a distal end position of a device and a position thereof after a predetermined time are searched for in a search unit, and the distal end position of the device in the three-dimensional image is calculated in a computing unit. Then, a cross-sectional image of the three-dimensional image is displayed on a monitor.
Claims12
An image processing apparatus comprising:
- a first memory configured to store a desired volume three-dimensional image;
- a second memory configured to store a sequentially updated two-dimensional image;
- a processor configured to align the three-dimensional image with the two-dimensional image,
- to acquire a position of a device, and
- to calculate the distal end position of the device in the three-dimensional image;
- and
- a display configured to display the three-dimensional image and a sectional image of the three-dimensional image including the position of the device,
- wherein
- the display further is configured to display, in the three-dimensional image, a mark indicating three-dimensional coordinates of the position of the device;
- a position of the mark in the three-dimensional image is updated per heartbeat;
- and
- the sectional image is updated per heartbeat.
An X-ray diagnostic apparatus which displays an image by image processing of image data generated by detecting X-rays applied to a specimen and converting the X-rays to an electric signal, the X-ray diagnostic apparatus comprising:
- a first memory configured to store a desired volume three-dimensional image;
- a second memory configured to store a sequentially updated X-ray two-dimensional image;
- a processor configured to align the three-dimensional image with the X-ray two-dimensional image,
- to acquire a position of a device, and
- to calculate the distal end position of the device in the three-dimensional image;
- and
- a display configured to display the three-dimensional image and a sectional image of the three-dimensional image including the position of the device,
- wherein
- the display is further configured to display, in the three-dimensional image, a mark indicating three-dimensional coordinates of the position of the device;
- a position of the mark in the three-dimensional image is updated per heartbeat;
- and
- the sectional image is updated per heartbeat.
