1. An examination apparatus comprising: a radiation source configured to emit radiation; a detector array configured to detect radiation that has traversed an opening into which an object under examination is received while under examination; a guide mechanism for rotating the radiation source relative to the opening and relative to the detector array, wherein the detector array remains in a fixed position while the radiation source is being rotated using the guide mechanism; an ultrasound frontend component configured to transmit ultrasound waves into the object and to detect ultrasound waves reflected by the object while under examination; an immobilization device disposed between the radiation source and the opening and configured to substantially immobilize the object while under examination, the immobilization device defining a plurality of openings, wherein: a first portion of the ultrasound frontend component is sized to be received within a first opening of the plurality of openings, a second portion of the ultrasound frontend component is sized to be received within a second opening of the plurality of openings, and a third portion of the ultrasound frontend component is sized to rest on a top surface of the immobilization device, wherein: the third portion extends between the first portion of the ultrasound frontend component and the second portion of the ultrasound frontend component to bridge the first portion of the ultrasound frontend component with the second portion of the ultrasound frontend component and to concurrently suspend both the first portion of the ultrasound frontend component and the second portion of the ultrasound frontend component within the first opening and second opening while the object is under examination; an image reconstructor configured to generate a set of images of the object based upon the radiation detected by the detector array, a first image depicting a first cross-sectional slice of the object parallel to the top surface of the immobilization device and a second image depicting a second cross-sectional slice of the object parallel to the first cross-sectional slice of the object; and an ultrasound subsystem configured to generate an ultrasound image based upon detected ultrasound waves.
