Abstract

|
|
The purpose of this study is to evaluate the effects of sprue forms on castability. Six different sprue forms were studied to determine which one could be used to produce more complete castings with a Ni-Cr alloy.
The experiments was carried out the general radiogiaphic equipments, in order to figure out exposure dosage decreasing and usable of general radiography instead of film mammography.
The results were as follows :
1) In order to decrease of unsharpness on mammographic film, the anode of the instrument must to be placed on the chest wall.
2) The patient´s exposure dosage could be decrease by the breast compression, but the position of the localization lession were apperanced change.
3) Through the usage screen type film of medical, the image of sharpness was able to get enough at the 30 degree acryle wedge filter.
4) According to do my research, it is able to use mammography with the 40 KVP or higher condition in general clinic and Hospitals.
