Quality assurance procedure on a Huestis Styro-former--stay on the cutting edge

A review of variations in block positions on port film vs. simulator film at The Nashua Regional Cancer Center, Nashua, NH, prompted the development of a method of measuring the accuracy of hot wire cut molds vs. a "test" film. The procedure is done at a minimum of once a year, or when accuracy of the block cuts are suspect. This simple test insures a high degree of confidence that the resulting cut molds are appropriate for the clinical situation and the need to recut blocks as a result of an out-of-tolerance Huestis Styro-former is kept to a minimum.
