- W2036273603 abstract "Computers are used in Nuclear Medicine to maintain patient record files, to operate billing accounts, to keep up an isotope inventory and for data collection and analysis in conjunction with general laboratory equipment. This paper will be limited to the problems of static and dynamic gamma ray imaging. Gamma-ray imaging for nuclear medicine produces images of poor resolution and inadequate statistical accuracy. This situation is the result of the low gamma-ray flux emanating from the patient. Dose limitations together with the radionuclide properties determine this flux. The specific degree of resolution and counting statistics in any given example are the result of a compromise involving the imaging duration and instrument design. Improving resolution results in a decrease in sensitivity, thus a worsening of counting statistics which can be improved only by increasing the time taken to form the image. This is one of the problems that led to the use of computers for image processing. When nuclear medicine images are recorded directly, any error of intensity setting or other faults produce a bad image which cannot be easily repeated. In the case of dynamic studies the series cannot be repeated until the activity clears from the patient. Thus it ismore » of great practical importance to access and store the original data digitally so that a spoiled photograph can be repeated without much cost or delay.« less" @default.
