Abstract
A plurality of radiation images of an object is taken in different imaging positions. An area sensor which detects a radiation passing through the object is moved in a direction substantially parallel to the optical axis of the radiation. That the area sensor reaches one of the imaging positions is detected and the radiation is projected onto the area sensor only when the area sensor is in one of the imaging positions.
Claims10
A method of obtaining a plurality of radiation images of an object taken in different imaging positions, wherein the improvement comprises the steps of
- moving an area sensor, which detects a radiation passing through the object, in a direction substantially parallel to the optical axis of the radiation,
- detecting that the area sensor reaches one of the imaging positions, and
- projecting the radiation onto the area sensor only when the area sensor is in one of the imaging positions.
An apparatus for obtaining a plurality of radiation images of an object taken in different imaging positions, wherein the improvement comprises
- an area sensor which detects a radiation passing through the object,
- an area sensor moving means which moves the area sensor in a direction substantially parallel to the optical axis of the radiation,
- a switching means which performs switching between a projecting state, where the radiation is projected onto the object, and a non-projecting state, where the radiation is not projected onto the object,
- a position sensor which detects that the area sensor reaches one of the imaging positions, and
- a switching means control means which causes the switching means to switch from the non-projecting state to the projecting state when the position sensor detects that the area sensor is in one of the imaging positions.
A computer program for causing a computer to perform a procedure comprising the steps of
- moving an area sensor, which detects a radiation passing through the object, in a direction substantially parallel to the optical axis of the radiation,
- detecting that the area sensor reaches one of the imaging positions, and
- projecting the radiation onto the area sensor only when the area sensor is in one of the imaging positions,
- thereby obtaining a plurality of radiation images of an object taken in different imaging positions.
A computer readable medium in which is recorded computer program for causing a computer to perform a procedure comprising the steps of
- moving an area sensor, which detects a radiation passing through the object, in a direction substantially parallel to the optical axis of the radiation,
- detecting that the area sensor reaches one of the imaging positions, and
- projecting the radiation onto the area sensor only when the area sensor is in one of the imaging positions,
- thereby obtaining a plurality of radiation images of an object taken in different imaging positions.
