Nuclear medicine imagining devices :Imagining ,or producing pictures of the distribution of the radioactivity is the most important aspect of nuclear medicine.
Rectilinear scanner-It use a NaI(Tl) detectors.-Two images are made of the radiation distribution -It use a focused collimators-A few scanners have two detectors focusing each other.
Gamma camera- It produces an image while stationary.- It has a large NaI(Tl) scintillation crystal about 1 cm thick and 30 to 45 cm in diameter.- The scintillation are viewed through a light pipe by an array of 19 or 37 PTMs.- A computer can be used in conjunction with gamma camera to obtain quantitive information.- A parallel hole collimator is usually used with gamma camera
Two parallel plates having a p.d. of 200V among them are spaced 0.8mm apart. What is the electric field strength? Find also the flux density when the dielectric among the p
