چکیده
Figure 2: (left) Color-coded principal eigenvectors diagrams showing the local direction of maximal diffusion in eight central slices calculated from the acquired DTI data. The diagrams are fused with corresponding anatomical images (b0-images). For calculation, a FA threshold of 0.25 and a background removal threshold of 100 were used. (right) Tractography of the same kidney as shown in Figure 1 provides a spatial impression of the radial organized diffusion pattern of the renal medulla. The DTI rays were calculated using following parameters: FA-threshold 0.25; background removal threshold, 200.

The Benefits and implementations of Diffusion tensor imaging and Neural Fiber Tractography in Brain Surgery
Background and Aim: The methods for detecting brain activation with fMRI, MRI provides a way to measure the anatomical connections which enable lightning-fast communication among neurons that specialize in different kinds of brain functions. Diffusion tensor imaging is able to measure the direction of bundles of the axonal fibers which are all aligned. Besides mapping white matter fiber tracts,...

Natural ventilation is among those effective methods that is useful in hot dry climates. One of its important uses is in the atrium spaces in the office buildings. Although, as a passive solution, it has a significant impact on the reduction of energy consumption, the control of inlet and outflow of air as well as the control of air current temperature has always been a challenge for architects...
