Can initial diagnostic PET-CT aid to localize tumor bed in breast cancer radiotherapy: feasibility study using deformable image registration
BACKGROUND Localization of the tumor bed of breast cancer is crucial for accurate planning of boost irradiation. Lumpectomy cavity and surgical clips provide localizing information about tumor bed. However, defining the tumor bed is often difficult because of presence of unclear lumpectomy cavity and lack of certain information such as absence of surgical clips. In the present study, we evaluat...
متن کاملThe use of PET/CT in radiotherapy planning: contribution of deformable registration
INTRODUCTION Medical imaging provides information for diagnosis and staging, evaluation of treatment response, and also plays pivotal role in advanced radiotherapy treatment planning. In the era of the innovative conventional and functional imaging techniques, the main goal of radiation therapy, which is to maximize the dose to the target while minimizing the dose to adjacent healthy organs, ca...
متن کاملInter-fraction deformable registration of CT and Cone Beam CT images for adaptive radiotherapy
Recent advances in intensity modulated radiotherapy (IMRT) have allowed accurate and fast delivery of treatment dose in the patient. Daily changes in patient geometry need to be accounted for to take full advantage of the increased accuracy of the delivered dose. On-site imaging using cone beam CT and registration of the acquired image with the algorithm presented here provides tools for effici...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA contour-guided deformable image registration algorithm for adaptive radiotherapy.
In adaptive radiotherapy, deformable image registration is often conducted between the planning CT and treatment CT (or cone beam CT) to generate a deformation vector field (DVF) for dose accumulation and contour propagation. The auto-propagated contours on the treatment CT may contain relatively large errors, especially in low-contrast regions. A clinician's inspection and editing of the propa...
