Abstract
In a console, a control unit functions as an acquisition unit and a generation unit according to the present disclosure. The acquisition unit acquires a plurality of projection images obtained by irradiating a subject disposed between a radiation source and a radiation detector with radiation emitted from the radiation source at different irradiation angles and capturing the radiation with the radiation detector at each of the irradiation angles. The generation unit generates a slab image with a thickness corresponding to the range from a first height to a second height.
Claims20
An image processing apparatus comprising:
- a processor configured to:
- acquire a plurality of projection images obtained by irradiating a subject disposed between a radiation source and a radiation detector with radiation emitted from the radiation source at different irradiation angles and capturing the radiation with the radiation detector at each of the irradiation angles;
- and
- generate a slab image with a thickness corresponding to a range from a first height to a second height different from the first height, using a value of a first pixel in each of the plurality of projection images corresponding to coordinates of a pixel of interest in a tomographic plane whose height from a detection surface of the radiation detector is the first height and a value of a second pixel in each of the plurality of projection images corresponding to the coordinates of the pixel of interest in a tomographic plane at the second height.
A non-transitory recording medium storing an image processing program that causes a computer to perform:
- acquiring a plurality of projection images obtained by irradiating a subject disposed between a radiation source and a radiation detector with radiation emitted from the radiation source at different irradiation angles and capturing the radiation with the radiation detector at each of the irradiation angles;
- and
- generating a slab image with a thickness corresponding to a range from a first height to a second height different from the first height, using a value of a first pixel in each of the plurality of projection images corresponding to coordinates of a pixel of interest in a tomographic plane whose height from a detection surface of the radiation detector is the first height and a value of a second pixel in each of the plurality of projection images corresponding to the coordinates of the pixel of interest in a tomographic plane at the second height.
