Abstract
A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time.
Claims8
A computerized tomography apparatus comprising:
- data acquisition means for acquiring multidirectional projection data on a subject under examination by means of a scan operation;
- image reconstruction means for reconstruction tomography image data from said multi-directional projection data in a period of time less than a time required for said scan operation;
- and display means for displaying said tomography image data after a lapse of a given period of time from the termination of said scan operation.
A computerized tomography apparatus comprising:
- data acquisition means for acquiring first and second multi-directional projection data successively by performing a first and a second scan operation successively, said second multi-directional projection data is acquired after a lapse of a given period of time from the time said first multi-directional projection data is acquired;
- image reconstruction means for reconstructing first tomography image data from said first multi-directional projection data in a period of time less than a time required for said first scan operation and reconstructing second tomography image data from said second multi-directional projection data in a period of time less than a time required for said second scan operation;
- and
- display means for displaying said first tomography image data and displaying said second tomography image data after a lapse of said given period of time from the time said first tomography image data is displayed.
