Two-dimensional reference dosimetry of small and nonstandard fields using new radiochromic film methodology

Graduate Investigator: Benjamin Rosen

Summary of Research: Radiotherapy treatments with small and nonstandard fields are increasing in use as collimation and targeting becomes more advanced, which spares normal tissue while increasing tumor dose. However, dosimetry of small and nonstandard fields is more difficult than that of conventional fields due to loss of charged particle equilibrium, tight measurement setup requirements, and the volume-averaging effect of one-dimensional dosimeters. This work aims to create new two-dimensional dosimetry protocols using radiochromic film in conjuntion with novel readout and analysis methodologies.
