Projects
ProjectsMedical image viewer, SRView , developed for Linux and other UNIX workstations to provide a simplified framework for stand alone analyses. It is Tcl/Tk extensible. SRView operates on 2D and 3D images and graphics. It supports 3 orthogonal views with region of interest analysis. A variety of techniques are under development to compare PET, CT and MRI brain scans of various population groups.
Functional MRI for brain research. We are adding analysis extensions to the popular AFNI program. In one example, the same analysis extension was added to both AFNI and SRView to provide a template for such future analyses.
Visual - Robotic targeting system, Target, is a robotic targeting system used for guiding multiple electrodes into nerve tissue. One defines a safe level and defines a coordinate system by example. Then a simple mouse click on the computer screen causes an electrode to retract, move and insert within a specified distance of the selected point. Target coordinates multiple manipulators, stage, focus and image. Target runs on Windows XP, Mac OS X, and eventually Linux. Uses Märzhauser, Luigs& Neumann, Siskiyou Design, and Sutter motor controllers.
Demand liquid delivery system, Feeder, for behavioral studies. It is being used to study alcohol consumption by monkeys. Feeder runs on a Macintosh computer.
Cross platform foundation class library, CsLib, to be used as a basis for future C++ development. Purpose is to minimize OS and OS version dependent code so as to reduce maintenance and training costs.
Focal scoring system, Score, is used by groups of behavioral scientists to observe the behavior of animals. Results are merged and exported to statistical analysis programs. Score runs on Macintosh Powerbooks.
Synchronized electrophysiology and imaging program, Synapse,
runs on a Macintosh. Synapse combines control, acquisition and analysis
of both electrical signals and images in one program that uses the full
bandwidth of a Macintosh computer.
Laser Optical Mamography (LOM). We wrote the pre-clinical trial version
of Softscan which is a product of Aerospace
Research Technologies, Montreal. Eventually the company brought the
software development effort in house.
ISIS. Infrared Inspection System for printed circuit boards. This program compares the infrared image of test boards with known "good" boards to determine if the test board might have faults in manufacture. We wrote this application for Aerospace Research Technologies, Montreal.
Teleradiology. We wrote an x-ray image viewer which captures from a film scanner and is sensitive to work flow and image quality.
NIH Image Stage Controller. NIH Image is a general purpose analysis of gray scale images on Macintosh. This package controls the LUDL stage in three axes (x, y, focus). It uses a self calibration feature in which the user selects an origin and another location and then enters the displacement. The design makes it easy for Pascal or NIH Image Macro programmers to develop applications. The Stage controller is now in Synapse Image and in Target.
NIH Image DICOM reader. This extended the NIH Image import facility to read DICOM formatted medical images. The header may be dumped to a file and summary information written to a text window. Multiple images may be read to form a movie.
Energy Dispersive Spectroscopy (EDS). Spectra from an energy dispersive spectrometer attached to a JEOL electron microscope was fitted with multiple Gaussian functions. These were matched to a database of physical constants to do standard and standard less chemical analysis.
