Abstract
There is disclosed an X-ray computerized tomography apparatus capable of accurately and promptly carrying out a navigation of an operation, by real-time reconstructing and displaying an image of a slice in which an object such as an insertion object inside a subject exists. This X-ray computerized tomography apparatus is structured to include: an X-ray detection unit for detecting transmission X-rays from a plurality of directions Irradiated from an X-ray beam generation source and transmitted through a subject, a data acquisition unit for acquiring transmission data according to the transmission X-rays detected by the X-ray detection unit, an object position detection unit for detecting a position of an object inside the subject, according to a part of the transmission data, a reconstructing range determining unit for determining a slice to be image-reconstructed, according to the position detected by the object position detection unit, and an image reconstruction unit for reconstructing a tomographic image of a slice in which the object exists, according to a transmission data acquired by the data acquisition unit, the transmission data being acquired in the slice. Thus, the X-ray computerized tomography apparatus directly detects the position of the object from the acquired transmission data, and controls the image reconstruction, display or scanning, based on the detected position.
