Gantry (medical)
Gantry (medical)
The gantry (pronounced: /ˈɡæntri/) is a critical component in various medical imaging devices, such as Computed Tomography (CT) scanners and Linear Accelerator machines.
Etymology
The term "gantry" originates from the Old French word gantier, which means glove maker. In the context of medical imaging, it refers to the rotating part of the machine that houses the x-ray tube and detectors.
Definition
In medical imaging, a gantry is a framework that rotates around the patient, emitting and detecting radiation to create detailed images of the body's internal structures. The gantry can be adjusted to different angles to capture images from various perspectives.
Function
The primary function of a gantry in medical imaging is to provide a stable and precise platform for the radiation source and detectors. It rotates around the patient, allowing the machine to capture images from different angles. This rotation is crucial in creating three-dimensional images of the patient's body, which can aid in diagnosing and treating various medical conditions.
