Abstract
An electronic x-ray imaging array is provided by combining a two-dimensional photosensitive array with a structured scintillator array, having a common array pattern and suitable alignment marks thereon, by bonding them face-to-face in alignment for direct coupling of x-ray luminescence from the scintillator array to the photosensitive array.
Claims12
A method of forming an x-ray imaging array comprising:
- providing a photosensitive imaging array including a plurality of photosensitive imaging cells arranged in a predetermined primary array pattern, said photosensitive imaging array including a first set of reference features having a predetermined positional relationship to said primary array pattern of said photosensitive imaging array;
- forming an array of scintillator elements on a separate scintillator substrate, said scintillator elements being arranged in said predetermined primary array pattern, said scintillator array including a second set of reference features having a predetermined positional relationship to said primary array pattern of said scintillator array and which are complementary to said first set of reference features;
- bringing said photosensitive imaging array and said scintillator array into close proximity;
- applying an optical coupling medium between said imaging array and said scintillator array, said coupling medium being fluid during adjustment of the relative positions of said arrays to form a high integrity optical coupling between said arrays;
- adjusting the relative positions of said arrays until the relationship of said first reference features to said second reference features indicates that said primary array pattern of said scintillator array and said primary array pattern of said photosensitive imaging array are properly disposed to be secured in alignment;
- and
- securing said photosensitive imaging array and said scintillator array to maintain said photosensitive imaging array and said scintillator array in an aligned condition.

An x-ray imaging array comprising:
- a photosensitive imaging array including a plurality of photosensitive imaging cells arranged in a predetermined primary array pattern, said photosensitive imaging array including reference features;
- an array of scintillator elements disposed on a support plate and arranged in said predetermined primary array pattern, said scintillator array including reference features which are complementary to those present on said photosensitive imaging array;
- and
- a curable optical coupling medium disposed between said photosensitive imaging array and said array of scintillator elements to provide high integrity optical coupling between said arrays;
- said photosensitive imaging array and said scintillator array being secured to each other with their respective reference features disposed in alignment.
