Binary Segmentation Masks for Registration of Bone Structures in CT Images
نویسندگان
چکیده
Rigid registration of bone structures in stacks of CT images can be improved by using a binary segmentation mask for the registration compared to using the segmented grey values directly. Three criteria are applied to the different reference and template datasets in order to quantify registration results. For all three criteria a statistically significant superiority of the technique using the binary segmentation masks is demonstrated. First results for a multimodal registration of a μCT with μMR dataset also show better results if binary segmentation masks are used for the registration.

Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملDeformation Analysis of Hoffa’s Fat Pad from CT images of Knee Flexion and Extension
Recent advances in medicine conjecture that certain body fat may have mechanical function in addition to its classical role of energy storage. In particular we aim to analyze if the intra-articular fat pad of Hoffa is merely a space holder or if it changes shape to provide cushioning for the knee bones. Towards this goal, 3D CT images of real knees, as well as a skeletal knee model with fat sim...

Intensity Modulated Radiotherapy is a new technique enabling the sculpting of the 3D radiation dose. It enables to modulate the delivery of the dose inside the malignant areas and constrain the radiation plan for protecting important functional areas. It also raises the issues of adequacy and accuracy of the selection and delineation of the target volumes. The delineation in the patient image o...
متن کاملAutomatic Landmark Detection and Non-linear Landmark- and Surface-based Registration of Lung CT Images
Registration of the lungs in thoracic CT images is required in many fields of application in medical imaging, for example for motion estimation or analysis of pathology progression. In this paper, we present a feature-based registration approach for lung CT images based on lung surfaces and automatically detected inner-lung landmark pairs. In a first step, an affine pre-registration of surface ...

Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...
