Abstract: Presented are systems and methods that allow for interpolation of a 3-D volume from arbitrarily oriented 2-D medical images. The interpolation of 3-D volume from arbitrarily oriented 2-D images reduces or eliminates most constraints on image acquisition thereby allowing for, inter alia, freehand manipulation of an image acquisition device (e.g. an ultrasound transducer). Related utilities involve the use of prior information about a specific object of interest to interpolate a surface (e.g., 3-D surface) of the object from limited information obtained from very few 2-D images.

Abstract: An improved apparatus and method for position sensing of a medical tracker device are presented. The apparatus and method are designed to constrain, rotate, and track the position of a medical tool. o improve the position sensing of the tracker, a joint that provides two degrees of freedom may use a revolute gear pair together with a rotary sensor for angular motion sensing and a sliding/prismatic assembly together with a linear magnetic sensor for linear position sensing. Thus, the linear motion sensing and the angular motion sensing are decoupled.

Abstract: Various embodiments of systems and methods for managing a plurality of nodes in a distributed computing environment are described herein. Initially a request to process a to-be-processed request is received. Next one or more nodes from a plurality of nodes, included in a cluster, is identified to process the to-be-processed request. Next the to-be-processed request is divided into a plurality of sub-requests. Next the plurality of sub-requests are assigned to the identified one or more nodes and the generated additional node. A node failure of one of the one or more identified nodes is identified. Finally, one or more of the plurality of sub-requests assigned to the failed node is re-assigned to another node of the plurality of nodes.
