Results Significant changes were seen for radiation dose and image-quality scores between collimation levels. For each level of collimation and corresponding exposure setting the phantom was exposed 10 times. Recent reports state that over 1 million X-ray examinations of the skull and facial bones are performed in the UK [ 12 ] alone each year. Eat These 3 Things Instead. Improvements in image quality have been reported due to reducing secondary scatter radiation [ 1213 ]. Significance levels and mean dose values are shown in Table 6. Penetration of frontal bone without excessive density at lateral borders of skull, which shows the facial bones.

Collimation To investigate the effect of X-ray beam collimation in this study, three different radiation field sizes were used in the study.

Once this is completed firm recommendations on optimised levels of collimation with facial bone examinations will be available. Even though these things might interfere somewhat with the image, your doctor may still choose to perform an X-ray. If you are an out-patient and require a copy of the images then a disc of images can be made available within 5 working days after the x-ray. Constant beam energies of 72, 72 and 65 kVp were used for the OM, OM 30 and lateral projections, respectively. This program allowed observers to easily move between images and readily alter the window levels to potentially improve the appearance of the image. This phantom-based study investigated the impact of X-ray beam collimation on radiation dose to the lenses of the eyes and thyroid along with the effect on image quality in facial bone radiography.
