Abstract

An open-floored concave compensating filter was designed that produced a radiograph of uniform density, caused no artifacts due to its shape or position, and required little or no increase in exposure in most applications. Selective celiac, hepatic, shoulder, and pelvic angiography was performed with use of the filter; image quality was noticeably improved.
