Short communication Breast radiotherapy phantom design for the START trial
msra(2000)
摘要
The design of phantoms for use in radiotherapy involves a number of complex issues. This paper describes breast and chest wall phantoms that have been designed and constructed for the START trial. Four phantoms have been manufactured, including two two-dimensional phantoms used on the first round of audit visits to assess the ability of departments to plan with the required accuracy. Two further phantoms have been constructed and will be used in the second round of audit visits; one is a water-filled three-dimensional phantom for investigating off- axis dosimetry, the other is to be used to assess dose in the junction region between the tangential fields and the supraclavicular fossa field. The manufacturing and design process for each of the phantoms is discussed.
