3D Reconstruction of Subthalamic Nuclei from MRI

چکیده
In this paper, a novel 3D reconstruction of subthalamic nuclei is proposed for recognition and location analysis of subthalamic nuclei in the brain. The method utilizes a region based level set method to segment 2D subthalamic nuclei from two different MRI images. Via the location and registration of two subthalamic nucleus contours, each set of subthalamic nucleus slices from one T2-weighted MR image of the atlas is obtained, which satisfies the constraints from the other contour. Stacks of slices are used to construct 3D rendering of subthalamic nuclei. With its direct and effective visualization, 3D reconstruction of subthalamic nuclei has important and wide applications for the clinic diagnosis and treatment.

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU
Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
متن کاملUltra-High Field MRI Post Mortem Structural Connectivity of the Human Subthalamic Nucleus, Substantia Nigra, and Globus Pallidus
INTRODUCTION The subthalamic nucleus, substantia nigra, and globus pallidus, three nuclei of the human basal ganglia, play an important role in motor, associative, and limbic processing. The network of the basal ganglia is generally characterized by a direct, indirect, and hyperdirect pathway. This study aims to investigate the mesoscopic nature of these connections between the subthalamic nucl...
متن کاملCreation of Computerized 3D MRI-Integrated Atlases of the Human Basal Ganglia and Thalamus
Functional brain imaging and neurosurgery in subcortical areas often requires visualization of brain nuclei beyond the resolution of current magnetic resonance imaging (MRI) methods. We present techniques used to create: (1) a lower resolution 3D atlas, based on the Schaltenbrand and Wahren print atlas, which was integrated into a stereotactic neurosurgery planning and visualization platform (V...
متن کاملAnatomical situation of the subthalamic nucleus (STN) from midcommissural point (MCP) in Parkinson\'s disease patients underwent deep brain stimulation (DBS): an MRI targeting study
Abstract Introduction: It is demonstrated that the degree of clinical improvement in Parkinson's disease (PD) achieved by deep brain stimulation (DBS) is largely dependent on the accuracy of lead placement. In addition, individual variability in the situation of subthalamic nucleus (STN) is responsible for spatial inter-individual fluctuations of the real patient's target. Objecti...
متن کاملComparison of Two Quantitative Susceptibility Mapping Measurement Methods Used For Anatomical Localization of the Iron-Incorporated Deep Brain Nuclei
Introduction Quantitative susceptibility mapping (QSM) is a new contrast mechanism in magnetic resonance imaging (MRI). The images produced by the QSM enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. These nuclei are targets in many clinical applications and therefore their easy localization is a must. In this study, we aimed to i...
