Standardized radiation dose of four-dimensional CT can reduce lung damage

four-dimensional CT (4D-CT) technology can track theof lungmovement, which is beneficial to clinicians to reduce and optimize targeted radiotherapy and strengthen lung cancer treatmentThis is reported by DrRengan of the University of Pennsylvania at the 49th Annual Conference of radiotherapy andOncologyin October 2007DrRengan says 4D-CT is an exciting new technologyThe lungswith constant movement with breathing, making it difficult to treattumorthat accompany the
movement of the lungs4D-CT technology provides more accurate images of themovement of the lungs andtumors, helping to track the movement of tumors Dr Kang, of MD Anderson Cancer Center in Texas, USA, shows how lung-prone tumors move in different directions Using these images, physicians can see the smaller edges around the tumor, which can help reduce lung damage caused by radiation doses and toxic effects The retrospective study included 40 patients with phase III and IV non-small cell lung cancer, both subjected to 4D-CT and rapid non-breathing spiral CT tests The purpose of the study was to assess the effects of respiratory movement on lung volume, dose distribution, lung dose-capacity parameters, and to explore the 4D-CT radiotherapy program and dose-capacity mechanism of lung cancer patients The researchers observed that the effect of using different lung capacity definitions on dose-capacity barchart values varied widely This is the first study to assess the dose-capacity leading to varying degrees of 4D-CT, as well as to suggest standard (Huang Qiang)
