Provided are a three-dimensional X-ray CT apparatus, a three-dimensional CT image reconstruction method, and a program, which are capable of reducing an operating time. A three-dimensional X-ray CT apparatus includes: a CT imaging portion for continuously and relatively rotating a measurement system with respect to a subject to perform a CT imaging measurement for taking data on a plurality of transmission images for reconstructing a three-dimensional CT image of the subject; and an image reconstruction portion for reconstructing the three-dimensional CT image based on the data on the plurality of transmission images taken by the CT imaging portion and displaying the three-dimensional CT image. During a period in which the CT imaging measurement is being performed, the image reconstruction portion reconstructs the three-dimensional CT image based on already-taken data on transmission images and displays the three-dimensional CT image before the CT imaging measurement is completed.
A three-dimensional X-ray CT apparatus, comprising:
A three-dimensional X-ray CT image reconstruction method for continuously rotating relative angular positions of a subject and a measurement system to perform a CT imaging measurement for taking data on a plurality of transmission images for reconstructing a three-dimensional CT image of the subject, and reconstructing the three-dimensional CT image based on the taken data on the plurality of transmission images,
A program for causing a computer to function as, the computer being included in a three-dimensional X-ray CT apparatus for continuously rotating relative angular positions of a subject and a measurement system to perform a CT imaging measurement for taking data on a plurality of transmission images for reconstructing a three-dimensional CT image of the subject, and reconstructing the three-dimensional CT image based on the taken data on the plurality of transmission images, the CT imaging measurement comprising taking data on a plurality of transmission images for a primary measurement, and taking data on a plurality of transmission images for a secondary measurement, which is measured in succession to the primary measurement:
