各臓器における最適なシンチグラム黒化度(第2報)

抄録

The authors studied the optimum density of scintiphotogram for the various organs. The results are following. 1) Density-factor, dot-factor and scanning-speed of the scintillation scanners is changed by the density of scintiphotogram exceedingly. So, we must be understood the changeness of density and must not be too much swayed by the settled idea. 2) The optimum density of scintiphotogram is about 1.0. 3) Clinically, it is doubtfull that we apply to the ratio of the density of scintiphotogram without careful thought. But it will be usefull to conclude with following expression. (ratio of the density of scintiphotogram : [numerical formula])
