|---|---|
| SFDA Classification | Class IIa |
| Purpose of Use | Accurate detection of many diseases such as kidney, thyroid, heart and lung diseases and atomic scanning of the bones. Also, static or dynamic images of the human body can be created. |
| Work Location & End-User | Place of work: Radiology department. End User: Radiologist |
| Parts & Accessories | ● Collimator ● Shimmer, Crystal Nal (TA) ● light guide ● Photomultiplier tubes ● Electronic Preamplifier ● logical circuits ● Electronic Amplifier ● Computer data analysis |
| Operation | Single photons are emitted from the object, and due to the collimator, only the photons acting perpendicular to the detector hit the luminescence crystal which will convert the photons into visible light. The generated photons of light are directed and converted into an electric current in the photomultiplier tubes. This signal is then converted into an image. |
| Common Problems | A common problem with gamma cameras is the low sensitivity. |
