A component of a portable survey meter or stationary radiation monitor used to measure radioactive emissions. It includes a variety of designs and configurations consisting of a crystal or other form of scintillation material, a photomultiplier tube, a ligh...
A gamma ray, x-ray, neutron, alpha, and beta radiation counting instrument that measures scintillation light (or prompt fluorescence) produced by the interaction of the ionizing radiation and certain materials. A wide variety of inorganic crystals and plast...
A precise radiation counting instrument designed to measure radioactivity emanating from a radioactive tracer on labelled samples. Primarily used to count beta particles, the radioactive sample is dissolved or suspended in an organic scintillation fluid whe...
An electrically-powered, cassette-like device intended to be used as part of an x-ray system to detect x-ray images following exposure, and create a digital signal; it is not dedicated to imaging of a specific anatomy. It includes two types of transducing t...
A device designed specifically for use in diagnostic nuclear medicine imaging applications operating with an energy range of less than 500 kilo-electronvolt (keV). It consists of an array of small openings drilled or cast into a flat sheet or plate of lead ...
A device designed as a container to allow the safe deposit, collection and storage of radioactive materials including containers previously used for those materials (e.g., scintillation vials). This container consists of a metal and/or hard plastic disposab...
A survey meter or area monitor with a spectrometer to separate pulses received from a detector according to pulse size. Pulse size is proportional to energy of the detected radiation. It typically consists of a detector (usually a scintillation or semicondu...
An assembly of diagnostic devices that comprise a non-imaging nuclear medicine system designed primarily for radioactive iodine related thyroid uptake measurement and analysis applications. It can typically be upgraded with the addition of software and hard...
An electrically-powered, invasive component of an intraoperative gamma radiation detection system intended to be introduced into the body during a surgical procedure to detect and quantify gamma radiation emitted from previously-administered radiopharmaceut...
A device designed specifically for use in gamma camera or single photon emission computed tomography (SPECT) based planar positron imaging applications operating with an energy range above 500 kilo-electronvolt (keV). It consists of an array of small openin...
A conical shaped housing of lead or equivalent material with a single small opening of a fixed diameter at the tapered end of the cone. It projects an inverted image of photon distribution onto the system's crystal detector ensuring that only gamma ray acti...
An individual hollow-bore cylinder made of a dense material, e.g., lead (Pb), tungsten (W) or titanium (Ti), used to ensure that only gamma ray activity directly in front of the collimator channel reaches the scintillation crystal of the imaging or detector...
