Abstract
An image guiding device includes a gantry, an imaging source, an imager, and an image server. The imaging source, the imager and the image server are all mounted on the gantry. The imager is connected to the image server. The imaging source is arranged to face the imager. The imaging source emits X-rays. The imager receives X-rays passing through an affected part of a patient, generates projection data based on the received X-rays, and sends the projection data to the image server. The image server processes the projection data to obtain an image of the affected part.
Claims19
An image guiding device, comprising:
- a gantry;
- an imaging source mounted on the gantry, wherein the imaging source is configured to emit X-rays;
- an imager arranged on the gantry in a fashion of facing the imaging source, wherein the imager is configured to receive the X-rays passing through an affected part of a patient and generate projection data according to the received X-rays;
- and
- an image server mounted on the gantry and connected to the imager, wherein the image server is configured to receive the projection data and process the projection data to obtain an image of the affected part, and the image server comprises an image reconstruction unit;
