Abstract

|
|
With this experiment we have conculusion as follows. Total FCR-9501 are 8 units. All hospitals under study are conducting the high kvp radiographing with 115-120kvp and 410mAs. The mean value of the chest exposure was 0.5240.301mGy. The percentage of the absorber finding from phantom was more the 85% with a range of 100136 kvp. The mean dose from phantom was 0.990mGy with 124 kvp and 16 mAs. There is no difference in the amount of information due to the change of kvp and mAs, but some coarseness of images can be seen in the magnified images. The resolving power was about 1.5/mm. The increase and decrease of 1030 kvp from common kvp has not influenced on the amount of information. The exposure could be reduced by 0.1700.570mGy.
