Safety programming--epidemiological considerations for the occupational health professional.

1. Epidemiological research incorporates four major areas of study, each involving different methods: observations, natural experiments, experimental epidemiology, and theoretical model construction. 2. Constant tracking of health outcomes and changes is invaluable in determining specific preventive actions that will minimize employee health changes or injuries. 3. Health care professionals who are responsible for occupational safety and health should review their current prevention practices.

A linear tomographic alignment test object.

A simple test object that accurately assesses linear tomographic tube and cassette-movement alignment is described. This device consists of two offset pinholes, one located above and one below the fulcrum plane. The test object is easy to make and can be used during the installation and performance testing of conventional tomographic units.

The scanning grid: a novel and effective bucky movement.

A grid consisting of a focused array of radiopaque strips has been constructed. No interspace material is employed, and, during an exposure, the arrangement moves so that the grid strips remain focused and a uniform film density is obtained. Preliminary measurements and radiographs of patients indicate that such a device is a practical and effective method of suppressing scatter.
