In the radiographic image diagnosis of Regio viscerocranium, such problems have been noted as the difficulty in collecting accurate information from a single radiographic image because of the excessive object-contrast unavoidable due to the compilcated structure of the Regio viscerocranium, or the film economy as several radiographs need to be taken by different radiographic exposures for above reason, which further leads to the denger of dosing unnccessarily over exposure of radiation to the patient. The author reviewed what was developed and iotroduced by Edholm and Jacobson (1971), selecting from the several compensating filters devised to solve these problems, and have obtained radiograph of excellent image quality with which the film contrast was not hurt but the object-contrast was improved to deliver better image imformation. Besides, the dose to the patient may be reduced by about 30% less than the normal radiography. In order to comply with the recommendations of the ICRP Publication No.16 which demand reduction of the dose to the patient as well as the diagnosis by high image quality, it is considered that this kind of compensating filter should be used more extensively.
