Final answer:
In a CT imaging system, the gantry includes the X-ray tube and detector array, which rotate around the patient to obtain cross-sectional images, while the control panel is not part of the gantry.
Step-by-step explanation:
The components that are part of the gantry of a CT imaging system include the X-ray tube and the detector array. The gantry is the part of the CT scanner that houses the X-ray source and the detectors and rotates around the patient to capture images from various angles. The X-ray tube emits the X-rays, while the detector array captures the X-rays after they have passed through the patient's body. This information is then used to construct a detailed cross-sectional image of the body. The control panel is not part of the gantry but rather part of the operating console where the technician controls the CT scan process.
