This research program is focussed on treatment of cancerous tumors with small radiation fields. In radiotherapy, using very small fields, sometimes a few mm in diameter, allows a tumor "painting" and an avoidance of surrounding healthy organs. However, the small size of fields lead to technical difficulties in radiation dose calculation, deposited dose measurement, thus in treatment planning. Our objective is to study dose calculation with small fields, optimize treatment planning and validate treatment security through adapted quality assurance. To conduct this research, we will use our CyberKnife. This unit was the first installed in Canada, in 2009.

这个研究项目的重点是用小辐射场治疗癌性肿瘤。在放射治疗中，使用非常小的视场，有时直径只有几毫米，可以使肿瘤“涂漆”，并避免周围的健康器官。然而，由于场区面积小，在辐射剂量计算、沉积剂量测量等方面存在技术困难，因而在治疗计划方面存在技术困难。我们的目标是研究小范围的剂量计算，优化治疗计划，并通过适应性质量保证验证治疗安全性。为了进行这项研究，我们将使用我们的射波刀。该装置于2009年首次在加拿大安装。
