Detection of patient setup errors with a portal image – DRR registration software application
The purpose of this study was to evaluate a custom portal image - digitally reconstructed radiograph (DRR) registration software application. The software works by transforming the portal image into the coordinate space of the DRR image using three control points placed on each image by the user, and displaying the fused image. In order to test statistically that the software actually improves ...
متن کاملIntensity-based Registration of Portal Images for Patient Positioning in Radiotherapy
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 sev...
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...
متن کاملFast 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,...
متن کاملContourlet-Based Edge Extraction for Image Registration
Image registration is a crucial step in most image processing tasks for which the final result is achieved from a combination of various resources. In general, the majority of registration methods consist of the following four steps: feature extraction, feature matching, transform modeling, and finally image resampling. As the accuracy of a registration process is highly dependent to the fe...
