Each key step can be recognized in the final features, as the heart maintains a kind of “memory” of these passages. The various ontogenetic passages form the evolutive basis of the final configuration of the heart. For instance if you set sampling'' to 4, fiber tracking will be performed onevoxel out of four. It is the successor to the programs DTI Track and TensorViewer from the same author. It provides an easy to use interface to a number of visualization and analysis algorithms. If the set of reconstructed fiber tracts is too dense, you can set the sampling to a value greater than one. MedINRIA is a modular visualization and analysis program specializing in neuro imaging and particularly diffusion tensor (DT) MRI analysis. Methods will be developed that enable in-vivo as well as ex-vivo investigation of results derived from diffusion-weighted imaging techniques. The embryological development of the heart is one of the most fascinating phenomena in nature and so is its final structure and function. The next parameter controls the minimum length of fibers to be valid (in mm). Therefore, verification of diffusion parameters and derived virtual axonal projections is an important ongoing research topic. Presently, it is the only technique that enables in-vivo investigation of nerve fibers. Fiber Tracking: Description Tractography, or fiber tracking, is a process which runs at the end of the DTI processing pipeline, in the DTI Track module of MedINRIA 2. In addition to scalar diffusion parameters, the recently developed technique fiber tracking shows great promise for investigating the architecture of brain white matter. However, DTI data is fairly difficult to interpret in biological tissue as many factors affect the diffusion process and the MR signal. DTI provides quantitative measures which reflect the underlying tissue properties and exhibit markers in pathological states. Verification of diffusion-weighted imaging and nerve fiber trackingĭiffusion tensor imaging (DTI) is a magnetic resonance imaging technique that enables the measurement of restricted water diffusion in the human brain.
