LITE-1 mediates behavioral responses to X-rays in .

Rapid sensory detection of X-ray stimulation has been documented across a wide variety of species, but few studies have explored the underlying molecular mechanisms. Here we report the discovery of an acute behavioral avoidance response in wild type to X-ray stimulation. The endogenous UV-photoreceptor protein LITE-1 was found to mediate the locomotory avoidance response.

A suggested method for setting up GSI profiles on the GE Revolution CT scanner.

"GSI Assist" is the automatic exposure control (AEC) system for dual-energy acquisitions on the GE Revolution CT scanner. This paper describes the user options of GSI Assist, and describes the method developed at UAB Medical Center to simplify the use of GSI Assist without adversely affecting the AEC Operation.

Trade-off between pulse rate and radiation dose during modified barium swallow examination: what is the reality?

Aim: To evaluate the effect of modification of dose mode and frame rate on patient radiation dose during modified barium swallow (MBS) examinations.

Materials And Methods: A retrospective review was undertaken of consecutive MBS examinations performed over 6 months in the inpatient setting. Patients were divided into two cohorts: pre-implementation of the MBS Impairment Profile (MBSImP; low rate, normal dose) and post-implementation (high rate, low dose).

High-ratio grid considerations in mobile chest radiography.

Purpose: Grids are often not used in mobile chest radiography, and when used, they have a low ratio and are often inaccurately aligned. Recently, a mobile radiography automatic grid alignment system (MRAGA) was developed that accurately and automatically aligns the focal spot with the grid. The objective of this study is to investigate high-ratio grid tradeoffs in mobile chest radiography at fixed patient dose when the focal spot lies on the focal axis of the grid.
