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,...
متن کاملFast 2D-3D Registration for Navigation System of Surgical Robot
This paper presents a new registration algorithm of 2D color images and 3D geometric models for navigation system of surgical robot. A 2D-3D registration procedure is used to superimpose a tumor model on an endoscopic image precisely, and is therefore indispensable for the surgical navigation system. And thus, the performance of the 2D-3D registration procedure influences directly the usability...
متن کاملFast DRR Generation with Light Fields
Computer-aided treatment planning greatly improves the therapeutical index in radiotherapy. However, treatment plans need to be registered with the actual patient position on the treatment device before therapeutical irradiation can be started. Registration is commonly carried out by comparing a set of 2D control radiographs of the patient, the so-called portal images (PI), with 2D synthetic ra...
متن کاملProgressive Attenuation Fields: Fast 2D-3D Image Registration Without Precomputation
Computation of digitally reconstructed radiograph (DRR) images is the rate-limiting step in most current intensity-based algorithms for the registration of three-dimensional (3D) images to two-dimensional (2D) projection images. This paper introduces and evaluates the progressive attenuation field (PAF), which is a new method to speed up DRR computation. A PAF is closely related to an attenuati...
متن کاملRobust and Fast 2D/3D Image Registration using Regression Learning
In computer vision and image analysis, image registration between 2D projections and a 3D image while obtaining high accuracy and real-time computation is challenging. In this paper, we propose a novel method that can speedily detect the object’s 3D rigid motion or deformation from a small set of its 2D projection images. The method consists of two stages: registration and pre-registration lear...
