Gamma Camera Vs Spect . Broadly, components of a gamma camera and spect imaging device consist of a detector (collimator, detector, photomultiplier tube, and preamplifier), processing (position logic circuit, amplifier, correction circuit, pulse height analyzer), and display (monitor) units (cherry et al., 2003). This advantage can be put to use in one of three ways.
Gamma Camera Vs Ct Scan ct scan machine from ctscanmachines.blogspot.com
A positron is a particle with roughly the same mass as an electron but oppositely charged. This is a common feature of gamma cameras that are to be used for spect because it allows two different projection images to be acquired simultaneously. The presence of an intermediate positronium in pet.
Gamma Camera Vs Ct Scan ct scan machine
While czt utilizes direct conversion, csi uses indirect conversion with the aid of photodiodes. It is used for clinical studies producing better image and making diagnosis easier. Then, we take that data and process it using a back projection algorithm to create transaxial slices (think of a ct) The simplest is the pinhole camera,.
