项目摘要
DESCRIPTION (Adapted from Applicant's Abstract): The applicants proposed to
develop an x-ray beam equalization technique for digital fluoroscopic
applications that will produce an equalized radiograph with minimal image
artifacts and tube loading. More specifically the aim are: (1)
Investigation of the effect of piston size and the extent of focal spot
blurring on image equalization using physical phantoms. (2) design and
construction of the necessary hardware and software for an automated image
equalization system. (3) Investigation of the hypothesis that x-ray beam
equalization produces an image with significantly improved signal-to-noise
ratio (S/N) and minimal image artifacts using physical phantoms. (4)
Investigation of the hypothesis that x-ray beam equalization produces
significantly improved iodine quantification using physical phantoms. (5)
Investigation of the hypothesis that the x-ray beam equalization technique
can be reliably utilized during coronary angiography using a swine animal
model. The results of this research will provide fundamentally improved
images for both low and high frame rate applications. This technique has
several potential applications. One of the applications is the elimination
of bright spots and improvement of image S/N in digital angiographic images.
This is particularly true for cardiac imaging where the heart is very dense
near a very transmissive lung field which causes a significant S/N
degradation over the heart region. The elimination of bright spots by x-ray
beam equalization allows the entire image to be acquired with optimal S/N.
Furthermore, this technique provides significantly improved iodine
quantification in the under penetrated regions of the image.
