Among other things, one or more systems and/or techniques are described for dynamically adjusting, in a fan-angle direction, attenuation of radiation during an examination of an object such that portions of the object that are not represented in resulting (tilted/targeted) images of the object are exposed to less radiation than portions of the object that are represented in resulting (tilted/targeted) images of the object. As a rotating gantry is rotated, blades of a pre-object collimator are dynamically repositioned to selectively attenuate emitted radiation. A collimator adjustment component may be configured to determine how to reposition the blades based at least in part upon at least one of a desired tilt of the resulting (tilted) image(s), a translational position of the object, and a gantry rotation angle, for example.

Among other things, one or more tiles for an indirect-conversation radiation detector array are provided herein. Respective tiles comprise a detector sub-assembly and an electronic sub-assembly, which are operably coupled together, yet selectively removable, via a connection interface. When an electronic sub-assembly portion of a tile, which comprises a signal acquisition system (e.g., an integrated circuit, such as an application specific integrated circuit (ASIC)), functions improperly, the electronic sub-assembly portion of the tile may be selectively removed for repair/replacement without removing and/or replacing the detector sub-assembly (e.g., which may be much more costly to replace). Similarly, when the detector sub-assembly portion of a tile functions improperly, the detector sub-assembly portion of the tile may be selectively removed for repair/replacement without removing and/or replacing the electronic sub-assembly portion of the tile (e.g., although some manipulation of the properly functioning sub-assembly may occur).
