Abstract
There is provided an X-ray CT apparatus that allows easy and correct confirmation of which position a bed can be moved to and which region can be imaged. The X-ray CT apparatus performs imaging for obtaining a scanogram 301 (S101), displays the scanogram 301 (S102), and calculates a transversely movable region 304 (S103). Further, the X-ray CT apparatus inputs size of a bow tie filter 103 (S201), inputs a transverse movement destination of a bed 106 (S105), calculates an imageable region on the basis of the size of the bow tie filter and the transverse movement destination 302 (S202), and displays the imageable region 305 (S203).
Claims13
An X-ray CT apparatus comprising:
- a reference image acquisition unit that acquires a reference image by irradiating a subject placed on a bed with X-rays,
- a movable region calculating unit that calculates a transversely movable region of the bed on the basis of height of the bed and size of the subject, and/or calculates an up and down movable region of the bed on the basis of position of the bed for the transverse direction and size of the subject,
- a movement destination setting unit that sets a movement destination of the bed within the transversely movable region and/or the up and down movable region calculated by the movable region calculating unit,
- a filter size setting unit that sets size of a filter for adjusting radiation intensity of the X-rays,
- an imageable region calculating unit that calculates an imageable region on the basis of the movement destination of the bed set by the movement destination setting unit and the filter size set by the filter size setting unit, and
- a displaying unit that displays the imageable region calculated by the imageable region calculating unit superimposed on the reference image.
An X-ray CT apparatus comprising a gantry that has an opening and can be tilted with respect to the vertical direction, and a bed that can move in the opening of the gantry, which is provided with:
- a reference image acquisition unit that collects a reference image by irradiating a subject placed on the bed with X-rays,
- a movable region calculating unit that calculates a movable region of the bed on the basis of positional information of the bed, tilt angle of the gantry, and size of the subject,
- a movement destination setting unit that sets a movement destination of the bed in the movable region calculated by the movable region calculating unit, and
- a displaying unit that displays the movable region of the bed and/or the movement destination of the bed set by the movement destination setting unit together with the reference image.
