Converting DICOM to NIFTI with Checkpoint is a short and simple process.  Load a DICOM volume, then go to the “Export” tab.  Under the volume section, select the NIFTI file format from the list provided in “Export format”.  The “Using these units” attaches new units (i.e.

What is isosurfacing?

Isosurfacing is a visualization technique for extracting a surface from 3D volumetric data, such as a CT or MRI scan. The technique, first developed by researchers at GE called Marching Cubes,  essentially started the 3D medical visualization industry.

What is joint congruence?

Joint congruence is the measurement of two opposing joint surfaces as they relate to one another considering the 3D shape contour of each bone at their interface. For example, relating the femoral condyle to the tibial plateau or the temperomandibular condyle to the fossa.

Image analysis is hard. To extract meaningful information to meet your analysis goals you often need to work with large, complex, multidimensional and multivariate data. I have found that the following methodology can be used to effectively design software to successfully analyze image data.

DICOM (Digital Imaging and Communications in Medicine) provides a necessary format for handling device connectivity. Most importantly, it provides a means for:

While DICOM (Digital Imaging and Communications in Medicine) provides a necessary format for handling device connectivity, it could be improved by addressing the following concerns.

A commonly occurring problem where two or more data sets must be aligned to one another for the purpose of comparison, blending, visualization, and analysis. Rotating, scaling, and translating the 2D or 3D data sets usually accomplish this so that the each correspond to one another based upon some specified error metric.
