Renal Imaging Gamma camera : Gamma camera The gamma camera is the principle instrument for imaging in nuclear medicine. It consists of large detector in front of which the patient is positioned. Allows to visualize functional information about a patient’s specific organ or body system. Gamma camera cont’d : Gamma camera cont’d Modern gamma camera is under computer control. Computer allowing the operator to select the study acquisition time,or the number of counts be acquired,to set the pulse height. Gamma camera - how does it work? : The Gamma camera collects gamma rays that are emitted from within the patient, enabling us to reconstruct a picture of where the gamma rays originated. From this, we can determine how a particular organ or system is functioning. Gamma camera - how does it work? Gamma Camera : Gamma Camera Once a radiopharmaceutical has been administered, it is necessary to detect the gamma ray emissions in order to attain the functional information. The components making up the gamma camera are the collimator, detector crystal, photomultiplier tube array, position logic circuits, and the data analysis computer. Gamma Camera : Gamma Camera Gamma camera : Gamma camera Gamma camera : Gamma camera Scintillation Detector : Scintillation Detector In order to detect the gamma photon, detector crystal is generally used in Gamma cameras. This is due to this crystal's optimal detection efficiency for the gamma ray energies of radionuclide emission common to Nuclear Medicine. Application of computer : Application of computer The image of the distribution of the Gamma-ray-emitting-radiopharmaceutical is produced in the scintillation crystal by a collimator. The Gamma rays,which are not visible to the eye,are converted into flashes of light by the scinitillation crystal. Application of computer cont’d : Application of computer cont’d This light is,in turn,transformed into electronic signals by an array of photomultiplier tubes (PMT) viewing the rear face of the crystal. These electronic signals will be digitized and converted into binary numbers,then will be sent to the computer. Renal Nuclear Medicine : Renal Nuclear Medicine Renal nuclear medicine is used to evaluate renal function and morphology. Renal scintigraphy is the best imaging modality for evaluation of functional parameters such as glomerular filtration rate and effective renal plasma flow.
