Deformable gel dosimeters for radiation therapy. My interest in this field is two-fold: first, the primary focus is on the development of new radiochromic materials for use in radiation therapy dosimetry and developing optical techniques to read them; second, applying gel dosimetry to answer questions in radiation therapy, especially where organ motion and deformation are considered. Development of poly(vinyl alcohol) cryogels to mimic the optical properties of tissues. Biophotonics is an emerging field in biological sciences that uses light to study tissue. Advances in this field will benefit from realistic models that mimic the mechanical and optical properties of body tissues. At present, very simple models are used to test new technologies prior to using them on living subjects. This program seeks to develop new optical materials that address the need for better tissue models to support further technology development in biophotonics. The mechanical and optical properties of poly(vinyl alcohol) cryogels (PVA-C) are well suited to this task. The product of this research will be an anatomically and optically correct model of a male pelvis. The primary end use of this model is in the field of photodynamic therapy; however, due to the material's tissue equivalence, other anticipated uses are in the field of radiation therapy for prostate cancer.
