Reduced Atlas Database and Its Application in Multi-atlas Segmentation
To simplify the problem of atlas selection in multi-atlas segmentation, we define Minimum Reduced Atlas Database (MinRAD), and give an algorithm of selecting MinRAD. Furthermore, nine types of MinRAD model are proposed based different similarity measures and input images, and their performances on multiatlas segmentation are compared in two databases. Finally, we give some advice on how to sele...
متن کاملGenerating Synthetic Computed Tomography and Synthetic Magnetic Resonance (sMR: sT1w/sT2w) Images of the Brain Using Atlas-Based Method
Introduction: Nowadays, magnetic resonance imaging (MRI) in combination with computed-tomography (CT) is increasingly being used in radiation therapy planning. MR and CT images are applied to determine the target volume and calculate dose distribution, respectively. Since the use of these two imaging modalities causes registration uncertainty and increases department w...
متن کاملMulti-atlas based segmentation of brain images: Atlas selection and its effect on accuracy
Quantitative research in neuroimaging often relies on anatomical segmentation of human brain MR images. Recent multi-atlas based approaches provide highly accurate structural segmentations of the brain by propagating manual delineations from multiple atlases in a database to a query subject and combining them. The atlas databases which can be used for these purposes are growing steadily. We pre...
متن کاملDevelopment and Implementation of a Corriedale Ovine Brain Atlas for Use in Atlas-Based Segmentation
Segmentation is the process of partitioning an image into subdivisions and can be applied to medical images to isolate anatomical or pathological areas for further analysis. This process can be done manually or automated by the use of image processing computer packages. Atlas-based segmentation automates this process by the use of a pre-labelled template and a registration algorithm. We develop...
متن کاملThe Relational Database Aspects of Argonne's ATLAS Control System
∗ Undergraduate Research Participants Abstract Argonne’s ATLAS (Argonne Tandem-Linac Accelerator System) control system comprises two separate database concepts. The first is the distributed real-time database structure provided by the commercial product Vsystem [1]. The second is a more static relational database archiving system designed by ATLAS personnel using Oracle Rdb [2] and Corel Parad...
