Abstract
An X-ray computer tomography apparatus which performs prep scanning prior to main scanning to acquire information for use in reconstruction of a tomographic image for diagnosis, the main scanning including rotary scanning around a rotation axis, and axial scanning along the rotation axis, the X-ray computer tomography apparatus includes determination unit which determines a speed based on a change of a characteristic amount concerning information obtained by the prep scanning, and a unit which controls, to the determined speed, a speed of the axial scanning in a period from the start to the completion of the main scanning.
Claims10
An X-ray computer tomography apparatus which performs prep scanning prior to main scanning to acquire information for use in reconstruction of a tomographic image for diagnosis, the X-ray computer tomography apparatus comprising:
- determination unit which determines a speed based on a change of a characteristic amount concerning information obtained by the prep scanning;
- and
- a unit which controls, to the determined speed, a speed of a axial scanning in a period from the start to the completion of the main scanning.
An X-ray computer tomography apparatus which performs prep scanning prior to main scanning to acquire information for use in reconstruction of a tomographic image for diagnosis, the X-ray computer tomography apparatus comprising:
- a determination unit which determines a timing to start the main scanning based on an inclination of a change of a characteristic amount with time concerning information obtained by the prep scanning;
- and
- a unit which controls the X-ray computer tomography apparatus to start the main scanning at the determined timing.
