Methods and systems are disclosed for detecting a source (such as, e.g., radioactive and chemical sources) using a plurality of networked sensors communicating with a central processor over network. A method can involve injecting a simulated source in the system of networked sensors for use in operational training and/or testing.

Injection of simulated sources in a system of networked sensors

A large system of networked sensors requires the management and distribution of sensor data via an intelligent server (SmartServer). In this network of sensors, one or more SmartServers use the underlying processes of source detection to optimize network data flow.

Methods and systems for detecting a material source using a server and networked sensors

Efficient techniques and devices for detecting, locating, tracking, and identifying radiation sources using a network of one or more detectors are disclosed.

Spectral segmentation for optimized sensitivity and computation in advanced radiation detectors

The intraoperative calibration of an arbitrary surgical instrument relative to a surgical navigation digitizing system is achieved by a calibration guide. The calibration guide is established in position and orientation relative to the digitizing system coordinate system. The surgical instrument is aligned to the calibration guide during calibration to establish its probe and end orientation in the digitizer coordinates. The instrument carries a marker structure which is trackable in the digitizer coordinates to enable tracking by rigid-body transformation of the instruments probe and end position after calibration in the calibration guide.
