Abstract
The present invention presents a beam shaper for radiation imaging comprising a hollow beam shaper body filled with radiation attenuating gas. Radiation attenuation can be changed by adding or removing pressure to the gas or the housing containing the gas, making it suitable for use as a dynamic beam shaper in 3D radiation imaging.
Claims13
A dynamic beam shaper for a 3D imaging system comprising:
- a hollow beam shaper body that has a flexible housing containing a radiation absorbing gas for attenuating radiation of a radiation beam;
- pressure inducer that is arranged to induce a pressure to the hollow beam shaper body, wherein an attenuation profile of the beam shaper body is adaptable based on the induced pressure, and wherein the attenuation profile varies locally within the beam shaper body such that there is no homogeneous attenuation profile over a length of the beam shaper body in a path of the radiation beam.
A method for attenuating a radiation beam for a 3D imaging system, comprising:
- providing a dynamic beam shaper that comprises a hollow beam shaper body that has a flexible housing containing a radiation absorbing gas for attenuating radiation of the radiation beam;
- and
- inducing a pressure to the hollow beam shaper body, wherein an attenuation profile of the beam shaper body is adapted based on the induced pressure, wherein the attenuation profile is varied locally within the beam shaper body such that there is no homogeneous attenuation profile over a length of the beam shaper body in a path of the radiation beam.
