Current Projects of David A. Reimann

• Parallel Algorithms for Computed Tomography

  I am looking at implementing parallel algorithms for computed tomography on heterogeneous clusters of workstations using MPI.

• Roundoff and Quantization Error in Computed Tomography

  I am looking at how roundoff and quantization error effects the accuracy of reconstructed images.

• 3D Computed Tomography at a Microscopic Scale

  We are developing a research 3D x-ray microscope with 10 micometer resolution. This machine employs computed tomography principles at a microscopic scale. We have developed a similar system for 50-100 micrometer resolution.

• Analysis of Spatial Resolution for 2D Imaging Systems

  I am researching simple test objects to measure spatial resolution of 2D images.

• Analysis of Spatial Resolution for 3D Imaging Systems

  I have looked at spherical test objects to measure spatial resolution of 3D images from 3D imaging systems.

• Analysis of Microscopic Images

  I have developed software to analyze surface area, volume, and orientation of microstructure. I plan on assessing the accuracy and precision of these methods.

• Hardcopy Display of Three Dimensional Information

  I am looking at some interesting ways to map spherical domain measures to hardcopy devices.

• Geometric Distortion Correction in X-Ray Image Intensifier Systems

  I am looking at accuracy and precision of distortion correction applied to x-ray image intensifier systems.

• Analysis of Projectional Images

  I am interested in determining what 3D information can be determined from limited projection views.
