Intensity-based Registration of Portal Images for Patient Positioning in Radiotherapy
نویسندگان
چکیده
Radiotherapy is the second most frequent type of cancer treatment after surgery and before chemotherapy. Its aim is to deliver a lethal dose to the tumour with high-energy X-rays produced by a medical linear accelerator, while sparing surrounding healthy tissue. To improve the effectiveness of X-rays, the treatment is fractioned in several sessions (e.g. five sessions per week during six or seven weeks).

Fast DRR generation for intensity-based 2D/3D image registration in radiotherapy
Conformal radiotherapy requires accurate patient positioning according to a reference given by an initial 3D CT image. Patient setup is controlled with the help of portal images (PI), acquired just before patient treatment. To date, the comparison with the reference by physicians is mostly visual. Several automatic methods have been proposed, generally based on segmentation procedures. However,...

Introduction: The accuracy of patient positioning plays an important role for radiotherapy tasks. Short and automated Quality Assurance (QA) programs are becoming one of the challenging tasks in Radiotherapy. The current study, investigates the accuracy of treatment couch positioning with four degrees of freedom (4DoF) using a fast and accurate method based on an image acquired...
متن کاملTowards Automatic, Model-Driven Determination of 3D Patient Setup Errors in Conformal Radiotherapy
The accurate and quantitative determination of three-dimensional patient setup errors in conformal radiotherapy, including setup errors due to out-of-plane rotations, requires methods for registering pre-treatment, three-dimensional planning CT images with intra-treatment, two-dimensional portal images. We have developed a method for performing such a registration based on structural models tha...
متن کاملAutomatic registration of portal images and volumetric CT for patient positioning in radiation therapy
The efficacy of radiation therapy treatment depends on the patient setup accuracy at each daily fraction. A significant problem is reproducing the patient position during treatment planning for every fraction of the treatment process. We propose and evaluate an intensity based automatic registration method using multiple portal images and the pre-treatment CT volume. We perform both geometric a...
