Scintillating array with alignment features

A method of fabricating a scintillator module for a CT detector, the method comprising:

• forming an array of pixelated scintillators extending in a first direction at a first spacing, and extending in a second direction, orthogonal to the first direction, at a second spacing;
• adhering a reflector to the array and between the pixelated scintillators, the reflector having a first thickness;
• forming a plurality of notches with the reflector, the notches having a second thickness that is greater than the first thickness;
• positioning an anti-scatter grid on the reflector, the anti-scatter grid having a plurality of plates, each plate extending along a length such that, when the CT detector is positioned in a CT system, the length of the plates extend approximately toward a focal spot of the CT system, the plurality of plates separated from one another at one of the first spacing and the second spacing, wherein two of the notches have a gap therebetween that engages one of the plates;
• and
• applying an adhesive to the gap to adhere the one plate to the reflector.

A CT system comprising:

• a rotatable gantry having an opening for receiving an object to be scanned;
• an x-ray tube having a focal spot from which x-rays emit;
• a detector comprising one or more scintillator modules for receiving x-rays from the focal spot, each of the one or more scintillator modules comprising:
• an array of pixelated scintillators extending in a first direction at a first spacing, and extending in a second direction, orthogonal to the first direction, at a second spacing;
• a reflector on the array and between the pixelated scintillators, the reflector having a first thickness, the reflector forming a plurality of notches having a second thickness that is greater than the first thickness;
• and
• an anti-scatter grid having a plurality of plates, each plate extending along a length such that the length of the plates extend approximately toward the focal spot, the plurality of plates separated from one another at one of the first spacing and the second spacing, wherein two of the notches have a gap therebetween that engages one of the plates;
• an adhesive positioned in the gap to adhere the one plate to the reflector;
• and
• a computer programmed to acquire imaging data and generate an image.
