摘要： A computer-based method and system for interactive volume rendering of a large volume data on a conventional personal computer using hardware-accelerated block filtration optimizing uses 3D-textured axis-aligned slices and block filtration. Fragment processing in a rendering pipeline is lessened by passing fragments to various processors selectively in blocks of voxels based on a filtering process operative on slices. The process involves generating a corresponding image texture and performing two-pass rendering, namely a virtual rendering pass and a main rendering pass. Block filtration is divided into static block filtration and dynamic block filtration. The static block filtration locates any view-independent unused signal being passed to a rasterization pipeline. The dynamic block filtration determines any view-dependent unused block generated due to occlusion. Block filtration processes utilize the vertex shader and pixel shader of a GPU in conventional personal computer graphics hardware. The method is for multi-thread, multi-GPU operation.

摘要： A method and a system for estimating a longitudinal relaxation time in magnetic resonance imaging. The method includes scanning at least one object to form a sequence of data with a plurality of flip angles; regressing linearly the formed sequence of data based on a first signal intensity model associated with the flip angles to obtain an initial estimation for said longitudinal relaxation time; and regressing nonlinearly the formed sequence of data based on a second signal intensity model associated with the flip angles so as to obtain a final estimation for the longitudinal relaxation time, in which the initial estimation is used as an initial guess for the longitudinal relaxation time based on the second signal intensity model.
