Checkpoint can help you convert those large micro CT scans into files that are more manageable. The following explains how to load a stack of TIF image files from a micro CT scanner and convert them into a NifTi (.nii) file type which Checkpoint can load.

Geometric morphometrics provides invaluable information in the areas of physical anthropology and medical research. By comparing differences in 3D anatomic structures it can help quantify an evolutionary feature or relationship, determine an organisms ontogeny or help improve diagnostics and surgical planning among many other applications.

What is RECIST?

RECIST (Response Evaluation Criteria in Solid Tumors) is a set of guidelines for clinicians to follow to determine cancer treatment effectiveness. Cancer treatment is complicated, multi-pronged, lasts for years, and significantly impacts the lives of the cancer patient and their family and friends.

Checkpoint facilitates shape anaysis for the tibia.  The following explains how to create a tibia population and perform a shape analysis on that population.

Checkpoint facilitates shape anaysis for the temporomandibular joint (TMJ).  The following explains how to create a population of TMJ condyles and perform a shape analysis on that population.

What is exophthalmometry?

Exophthalmometry is a method for measuring globe (eye) position for a patient. The general idea is to measure the globe position to determine whether or not globe malposition is present.

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.

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 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. Congruence analysis can result in:

The procrustes superimposition method calculates the procrustes average specimen, which removes scale from the specimens. The following covers the options available in Checkpoint’s Shape Analysis tab.  Under “Analysis method”, select “Generalized Procrustes Analysis”.

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.

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.

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

DICOM stands for Digital Imaging and Communications in Medicine. DICOM was created as a means for sharing patient data between various devices within a hospital environment. A common format is necessary to facilitate communication between devices produced by different manufacturers.

While a post-doc at UC Davis, I led the software development effort for the IDAV Landmark Editor in conjunction with my advisor Nina Amenta and colleague Eric Delson at Lehman College, NY.

Stratovan has been invited to give a short presentation on our latest progress at this years Med Tech Showcase in Sacramento, CA. SARTA is highlighting Stratovan because of our growth over recent years and our anticipated growth in the near future due to increasing work with the government.

Congresswoman Matsiu invited CEO David F. Wiley to participate in a round table discussion focusing on small business issues plaguing entrepreneurs in the current economy.

CEO Wiley participated as a panelist at the Intellectual Property and Licensing Agreements seminar held at Drexel University, Sacramento. This seminar was part of the SARTA Leadership Series of events, designed for to educate entrepreneurs and small business owners in the region.

This invitation only forum for local professional is intended to create a forum among the many physicians and biomedical engineers in our community who invent medical devices.
