Abstract
A radiographic image capturing apparatus includes a radiation source for applying a radiation to an object to be examined, a radiation detector for detecting the radiation which has passed through the object and converting the detected radiation into a radiographic image, a positional information acquiring unit for acquiring positional information of the object, and an image capturing angle changer for changing an image capturing angle of the radiation source with respect to the radiation detector based on the positional information in a stereographic image capturing process for capturing at least two radiographic images of the object by applying the radiation to the object from directions which are different from each other.
Claims8

- a radiation source for applying a radiation to an object to be examined;
- a radiation detector for detecting the radiation which has passed through the object and converting the detected radiation into a radiographic image;
- a positional information acquiring unit for acquiring positional information of the object;
- and
- an image capturing angle changer for changing an image capturing angle of the radiation source with respect to the radiation detector based on the positional information in a stereographic image capturing process for capturing at least two radiographic images of the object by applying the radiation to the object from directions which are different from each other.
A biopsy apparatus for use with a radiographic image capturing apparatus including a radiation source for applying a radiation to an object to be examined, a radiation detector for detecting the radiation which has passed through the object and converting the detected radiation into a radiographic image, a positional information acquiring unit for acquiring positional information of the object, and an image capturing angle changer for changing an image capturing angle of the radiation source with respect to the radiation detector based on the positional information in a stereographic image capturing process for capturing at least two radiographic images of the object by applying the radiation to the object from directions which are different from each other, the biopsy apparatus comprising:
- a biopsy region positional information calculator for calculating a three-dimensional position of a biopsy region in the object based on the at least two radiographic images;

A radiographic image capturing method comprising the steps of:
- acquiring positional information of an object to be examined with a positional information acquiring unit;
- changing an image capturing angle of a radiation source with respect to a radiation detector based on the positional information, with an image capturing angle changer;
- and
- performing a stereographic image capturing process for capturing at least two radiographic images of the object by applying a radiation to the object from the radiation source at changed image capturing angles which are different from each other.
A biopsy method comprising the steps of:
- acquiring positional information of an object to be examined with a positional information acquiring unit;
- changing an image capturing angle of a radiation source with respect to a radiation detector based on the positional information, with an image capturing angle changer;
- performing a stereographic image capturing process for capturing at least two radiographic images of the object by applying a radiation to the object from the radiation source at changed image capturing angles which are different from each other;
