Abstract: The present invention is a technique and apparatus for acquiring anatomic information used in diagnosing and characterizing abdominal aortic aneurismal disease and the like. This technique provides anatomic information, in the form of images, using a combination of a plurality of magnetic resonance angiography sequences, including a spin-echo and four contrast enhanced (e.g., gadolinium) magnetic resonance angiography sequences. The anatomic images may be used in, for example, pre-operative, operative and post-operative evaluation of aortic pathology, including aneurysms, atherosclerosis, and occlusive disease of branch vessels such as the renal arteries. The gadolinium-enhanced magnetic resonance angiography provides sufficient anatomic detail to detect aneurysms and all relevant major branch vessel abnormalities seen at angiography operation.

Abstract: It is generally known in relation to hydroelectric power stations that, before the water impinges on the turbine of the hydroelectric power station and there delivers its energy to the turbine, the water flows through a pipe. Depending on the respective nature of the hydroelectric power station that pipe can be a downpipe through which the water flows, according to the respective local factors, in dependence on the fall height and the amount of water. In one aspect of the invention, the flow speed of the water (fluid) can be adjusted in the region of the turbine. In one aspect, a turbine is arranged within a flow pipe. The turbine has a variable cross-section, and thereby, the through-flow cross-section within the pipe is variable.
