| Popis: |
The advantages of a 14 x 14 inch film of the chest compared with a standard size 14 x 17 inch one are as follows: 1) Saving of approximately 18 per cent in cost by purchase of the smaller size film. This figure is about $0.13 less per film and would represent a tremendous savings since millions of chest x-ray film examinations are being made in the United States today. A proportionately smaller total dollar saving but a higher percentage saving (20 per cent) would be effected by using a 4x4 inch film instead of the 4 x 5 inch one in photoroentgenography. 2) Lower volume doses to critical areas of the body as well as smaller skin and gonad doses are obtained when the beam collimator is used with a 14 x 14 inch film or the smaller 4 x 4 inch PR film. 3) Vital reduction of x-ray exposure to the mother and to the gonads of the fetus in prenatal x-ray examinations, either by using the 14 x 14 inch film or the 4x4 inch PR films. |
