Huestis Medical, Bristol, RI, has introduced an Automatic Collimator with new optional features. A cross hair laser target system facilitates quick and accurate patient positioning, spectral filters allow adjustment of beam quality across a broader range of techniques to improve image quality and reduce dose, and input port shuttering reduces penumbra and scatter to improve image sharpness and contrast. Integrated DAP mounting is also available. The same new features are also now available on the Huestis Manual Collimator. (800) 972-9222; .
