2.12.2015 - Our new paper on simulation of Time-of-Flight and Phase Contrast angiography is now available on-line. We encourage you to read it.
30.11.2015 - In the Downloads section we've added a link to a Xcode project where we implement a vascular tree growth simulation algorithm. Have a try :-). 6.10.2015 - Two new models of the carotid artery bifurcation have been added to the downloads database. 15.08.2015 - We are starting a new project on magnetic resonance simulation. This time we will work on kidney perfusion modeling. More information soon. |

Vessel modeling
In the human circulatory system there exist large arteries and veins (of diameter ranging from 1 cm to 2.5 cm), medium-size vessels (1-10 mm) and the small ones (< 1 mm). On the other hand, in-plane resolution of images acquireed in MR scanners reaches the limit of 0.4 mm × 0.4 mmm. In routine examinations voxel size is even larger and ranges the value of 1 mm3. Therefore, the constructed vessel models are limited to the large and medium scale.
The desgined models have relatively simple geometry, but they simultaneously incorporate characteristic lesion structures, such as narrowings and aneurysms. Below, sample models are presented. These synthetic vessel structures were used to create the template database of MRA images for the the need of validating vessel segmentation methods.
