This software computes new compositional and structural indices which indicate spatial distribution, heterogeneity and dispersity of each VH-IVUS-derived component within the plaque area and also in respect to the plaque-lumen border. We developed an automated computational system in Java for the analysis of both single cross-sectional segments and the whole length of the examined plaque (volumetric analysis). The following parameters were computed:
- the number of different solid segments and the area of the largest solid segment of each component within the plaque,
- the percent of the lumen border that is surrounded by each component,
- the number of different solid segments and the largest area of a solid segment of each component that adjoins the lumen border.
