Corridor4DM-SPECT grew out of clinical and research needs for a tool to efficiently and realistically display and quantify gated tomographic studies of heart blood flow as well as mechanical function. In essence, Corbett and Ficaro identified the need for a technology that would give access to the wide range of diagnostic information these studies provide. They ultimately developed a sophisticated computer software application for cardiac nuclear medicine image display and analysis.
In the 1990s, James Corbett, MD and Edward Ficaro, PhD joined forces at the University of Michigan to develop and automate quantitative software for SPECT cardiac imaging. In 1994 the Division of Nuclear Medicine at the University of Michigan began to routinely use the resulting software, 4D-MSPECT, at the University of Michigan Medical Center, for all patients referred for myocardial perfusion SPECT imaging. 4D-MSPECT is the first software for correcting SPECT data for photon attenuation.
In 1996, after the next release of the software, Ficaro and Corbett publish in Circulation the first clinical diagnostic results for TCT/ECT imaging showing quantitative results using the newly developed software algorithms. The results and software draw significant interest from ADAC, Picker, and Siemens, sparking initial interest in commercialization.
The first commercial contract with a major medical camera vendor for the distribution of the application, named 3D – MSPECT was signed in 1997. After the next major release in 2000, the software received its 510k approval from the FDA. The software was renamed 4D-MSPECT to reflect the time dimension in cineing gated studies in three spatial dimensions. A contract with a second major camera vendor was signed in the second half of 2000. Annual sales of the software began to grow significantly.
By the end of 2002, GE, Philips, and Siemens, were contracted as distributors of the 4D-MSPECT imaging software.
The University of Michigan granted the rights to 4D-MSPECT to Drs. Corbett and Ficaro in 2005. They founded INVIA so that the product could be further developed, new medical imaging products developed, and benefit made available to a larger patient population. 4D-MSPECT is the cornerstone of a family of INVIA imaging products known as Corridor 4DM.
The User-Centered Experience
"The strengths of 4DM-SPECT are its ease of use, flexibility, and many user configurable options."
