Claims23
A collimation apparatus comprising:
- a first ring comprising an array of crystals and a second ring comprising an array of radiation blocking elements, wherein said second ring is disposed inside said first ring, and
- wherein a portion of each crystal of said array of crystals is blocked by a radiation blocking element of said array of radiation blocking elements.
A positron emission tomography (PET) scanner comprising a collimation apparatus, said collimation apparatus comprising:
- a first ring comprising an array of crystals and a second ring comprising an array of radiation blocking elements, wherein said second ring is disposed inside said first ring, and
- wherein a portion of each crystal of said array of crystals is blocked by a radiation blocking element of said array of radiation blocking elements.
18-28. (canceled)
A method of fabricating a collimation apparatus comprising:
- providing a first ring comprising an array of crystals;
- and
- providing a second ring comprising an array of radiation blocking elements, said second ring disposed inside said first ring, wherein a portion of each crystal of said array of crystals is blocked by a radiation blocking element of said array of radiation blocking elements.
31-42. (canceled)
