Bioengineering Unit Reports Findings in Radiotherapy and Oncology

February 14, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Oncology. According to news originating from Pavia, Italy, by NewsRx correspondents, research stated, "Image-guided advanced photon and particle beam treatments are promising options for improving lung treatments. Extensive use of imaging increases the overall patient dose."

Our news journalists obtained a quote from the research from Bioengineering Unit, "The aim of this study was to determine the imaging dose for different IGRT solutions used in photon and particle beam therapy. Measurements were performed in an Alderson phantom with TLDs. Clinically applied protocols for orthogonal planar kV imaging, stereoscopic imaging, CT scout views, fluoroscopy, CT, 4D-CT and CBCT were investigated at five ion beam centers and one conventional radiotherapy department. The overall imaging dose was determined for a patient undergoing a lung tumor irradiation with institute specific protocols. OAR doses depended on imaging modality and OAR position. Dose values were in the order of 1 mGy for planar and stereoscopic imaging and 10-50 mGy for volumetric imaging, except for one CBCT device leading to lower doses. The highest dose per exam (up to 150 mGy to the skin) was recorded for a 3-min fluoroscopy. Modalities like planar kV or stereoscopic imaging result in very low doses (similar to 1 mGy) to the patient."

According to the news editors, the research concluded: "Imaging a moving target during irradiation, low-dose protocols and protocol optimization can reduce the imaging dose to the patient substantially."
