Gamma camera field uniformity c. Gamma camera resolution b. In nuclear medicine imaging match the following quality control procedures with the relevant choice.
The gamma camera itself does not emit any. The gamma camera also called a scintillation camera detects radioactive energy that is emitted from the patient s body and converts it into an image. The special camera and imaging techniques used in nuclear medicine include the gamma camera and single photon emission computed tomography spect.
The images are taken using the camera head. The gamma camera usually has a table often narrow on which the patient lies. A gamma camera is a machine that is able to detect and make images from the very small amounts of ionising radiation emitted from patients having a nuclear medicine study.
Hence an image of high quality is one that can reproduce this contrast in order to secure a correct diagnosis. In nuclear medicine the basis of image quality is the ability of the imaging device to detect differences in the uptake of a radiopharmaceutical in a lesion and its surroundings. This image can tell us whether the function of the liver is normal or abnormal or if sections of it are damaged from some form of disease.
The substance emits gamma rays while it is in the patient s liver and we can produce an image of its distribution using a nuclear medicine imaging system. It simultaneously detects radiation from the entire fov and enables the acquisition of dynamic as well as static images of the area of interest in the human body 67. The gamma camera also called scintillation camera is the most commonly used imaging device in nuclear medicine.

Nuclear medicine gamma camera images. A gamma camera γ camera also called a scintillation camera or anger camera is a device used to image gamma radiation emitting radioisotopes a technique known as scintigraphy the applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of medically injected inhaled or ingested radionuclides. The special camera and imaging techniques used in nuclear medicine include the gamma camera and single photon emission computed tomography spect. The gamma camera also called a scintillation camera detects radioactive energy that is emitted from the patient s body and converts it into an image. Diagnostic medical imaging diagnostic.
In nuclear medicine imaging radiopharmaceuticals are taken internally for example intravenously or orally. Then external detectors gamma cameras capture and form images from the radiation emitted by the radiopharmaceuticals this process is unlike a diagnostic x ray where external radiation is passed through the body to form an image.
