Conjoint A/Prof. Peter Greer - Selected Publications
Greer PB and Popescu CC, Dosimetric properties of an amorphous silicon electronic portal imaging device for verification of dynamic intensity modulated radiation therapy. Medical Physics, 30(7):1618-1627, 2003.
One of the earliest works examining whether new imaging devices in radiation oncology could be used to measure and verify the accuracy of dose delivery to patients. Receives 15 citations per year.
Greer PB, Correction of pixel sensitivity variation and off-axis response for amorphous silicon EPID dosimetry. Medical Physics, 32:3558-3568, 2005.
This paper lead to better understanding of using imaging systems to measure and verify patient dose in radiation oncology.
McCurdy BMC and Greer PB, Dosimetric properties of an amorphous-silicon EPID used in continuous acquisition mode for application to dynamic and arc IMRT. Medical Physics, 36(7): 3028-3039, 2009.
The first paper to comprehensively examine a new method of ensuring that patient treatment is accurate in radiation therapy using time-resolved dosimetry. This can ensure that errors would be detected as soon as they occur which is not possible with current techniques.
Vial P, Greer PB, Oliver L and Baldock C, Initial evaluation of a commercial EPID modified as a novel direct-detection dosimeter for radiotherapy, Medical Physics, 35(10): 4362-4374, 2008.
Development of a new design for imaging systems in radiation oncology that promises to both acquire high quality anatomical images and accurately measure dose. This work may lead to a new type of imaging system in radiation oncology.
Greer PB, Mortensen T.M., and Jose C.C, Comparison of two methods for anterior posterior isocenter localization in pelvic radiotherapy using electronic portal imaging, Int. J. Radiat. Oncol. Biol. Phys., 41: 1193-1199, 1998.
This paper concerned improving the accuracy of prostate radiation therapy treatments. It was one of the first investigations in radiation oncology using digital imaging systems to accurately measure the targeting of radiation beams to patient anatomy.
