Medis Presents QIvus 2.1 with Extended Support for Tissue Characterization and for OCT

Medis released on Sept 1, 2011 version 2.1 of its quantitative analysis software solution QIvus for intravascular ultrasound. This new version of the software has extended possibilities to review and analyze IVUS studies with tissue characterization data that visualize plaque and to also review and analyze optical coherence tomography (OCT) studies.

“We are continuously listening to our highly valued customers, and take their comments and wishes very seriously, so that we can come up regularly with new versions based on the wishes from the field. Both the clinical users, the researchers and the core lab users are very important to us. This version of QIvus 2.1 enables medical professionals to quickly analyze data acquired with all currently available intravascular imaging systems, meaning that we can process vendor-independent data sets,” said Daniel Garcia, VP M&S of Medis medical imaging systems. “We are well-known for our segmentation quality and that translates into tools by which the users can analyze image runs with a minimum of effort and to get more out of the data that is already available to them.”

One of the major strong points of QIvus is the extremely efficient editing capabilities of the otherwise automatically detected contours, which drastically reduces the time needed to obtain validated results from the large number of grayscale or OCT images. Analyzing IVUS or OCT image data sets becomes a matter of minutes.

This means that important data, such as plaque burden results in IVUS images can be obtained quickly and easily. In a similar way, the software provides detection of stent struts in OCT images, allowing assessment of stent malapposition and neo-intima formation.

Important new features include the IVUS-analysis of multiple stents in the same segment, the Z-offset correction in OCT image runs, and export of all analysis results to Excel, including OCT stent strut analysis and subsegment analysis, as well as improved support for Japanese and other multi-byte languages. Here again, the workflow for editing the OCT stent strut analysis has greatly improved.

For those who have data sets with tissue characterization available, QIvus 2.1 also offers the option to view and analyze the areas marked as plaque and calculate the distribution of the various plaque components. The software supports both Boston Scientific iMap™ and Volcano® VH® IVUS data sets. The iMap and VH data can be reviewed alongside the grayscale image data, and analyzed just as quickly.

All in all, the new QIvus 2.1 offers fast, accurate and reliable quantitative analysis for more types of intravascular image data sets, and builds upon the established reputation of the QIvus product.
