Pressure distribution analysis of X-Ray table mattresses.

Background: There is a risk of developing pressure ulcers from lying on an X-ray table mattress, if the mattress pressure redistribution properties are poor.

Aim: To assess the pressure redistribution properties of 'new' and 'in current clinical use' X-ray table mattresses.

Methods And Materials: Twenty one X-ray table mattresses, each of 2.

Evaluation of X-ray table mattresses for radiation attenuation and impact on image quality.

Introduction: Mattresses in the radiology department tend to be an overlooked aspect of imaging equipment. This paper evaluates the radiation attenuation characteristics of mattresses and the effect they have on image quality.

Methods: Thirteen mattresses (from new to 20 years of age) were evaluated.

Radiation dose from digital breast tomosynthesis screening - A comparison with full field digital mammography.

Objectives: To compare Mean Glandular Dose (MGD) and effective dose from digital breast tomosynthesis (DBT) screening with that from full field digital mammography (FFDM) screening.

Method: To simulate compressed breasts, two Perspex-polyethylene breast phantoms were used, one phantom for compressed breast in craniocaudal and the other for compressed breast in mediolateral oblique. An adult ATOM dosimetry phantom was loaded with high sensitivity thermoluminescence dosimeters; the phantom was then positioned on Hologic Selenia Dimensions mammographic machine to imitate DBT and 4-view FFDM screening.
