摘要： A simulation is performed by assigning tissue type properties to voxels of a medical image and manipulating the voxels based on the assigned tissue type properties and an input that prompts voxel manipulation. Voxels may also be created and eliminated in response to the input. Tissue type properties may include elasticity, ductility, hardness, density, and thermal conductivity. Manipulation may include changing at least one of voxel size, location, orientation, shape, color, grayscale, and tissue type property value. The input may include insertion of a virtual volume-subtending surgical or anatomic object. Simulations may include virtual motion, deformation of tissue, and radiological dissection for pre-operative planning.

摘要： A method and apparatus for evaluating acute stroke patients and for determining whether a stroke patient will benefit from the use of thrombolysis therapy includes obtaining measurements of the cerebral blood flow and cerebral blood volume of the brain of a stroke patient, determining ischemic areas of the brain where the ischemic areas comprise the measurements of cerebral blood flow which are less than a first value and creating a penumbra-infarct map of the ischemic areas of the brain using the measurements. The infarct area corresponds to the area of the brain where cerebral blood volume is less than a second value. The penumbra area corresponds to the area of the brain where cerebral blood volume is greater than this second value. The method also includes determining a ratio of penumbra size to the total of penumbra size and infarct size. When the ratio is greater than a predetermined value, the stroke patient is a candidate for thrombolysis therapy.

摘要： Systems and methods for accelerated arterial spin labeling (ASL) using compressed sensing are disclosed. In one aspect, in accordance with one example embodiment, a method includes acquiring magnetic resonance data associated with an area of interest of a subject, wherein the area of interest corresponds to one or more physiological activities of the subject. The method also includes performing image reconstruction using temporally constrained compressed sensing reconstruction on at least a portion of the acquired magnetic resonance data, wherein acquiring the magnetic resonance data includes receiving data associated with ASL of the area of interest of the subject.
