It is attached to the x-ray tube housing assembly and adjusts the size and shape of the x-ray beam to match the size and shape of a predefined target area or the shape of a x-ray cassette used for quality assurance purposes. It is used in radiation therapy applications to limit the effects of scattered radiation and to provide patient protection by limiting or eliminating exposure to non-target body areas during treatment. This device is specifically designed for use with an x-ray simulation or therapeutic x-ray system.</gmdnPTDefinition><implantable>false</implantable><gmdnCodeStatus>Active</gmdnCodeStatus></gmdn></gmdnTerms><productCodes><fdaProductCode><productCode>IYE</productCode><productCodeName>Accelerator, Linear, Medical</productCodeName></fdaProductCode></productCodes><deviceSizes/><environmentalConditions/><sterilization><deviceSterile>false</deviceSterile><sterilizationPriorToUse>false</sterilizationPriorToUse><methodTypes/></sterilization></device>
