Abstract
An improved method for reconstruction of medical images includes the acquisition of k-space data through MRI imaging. Subsequently, subsets of the k-space data are transformed into intermediate images by performing an inverse Fourier transform on selected sets. These intermediate images are saved to a PACS or other memory storage, and can be recalled later to reconstruct an image. By selecting various intermediate images, a user can vary both the spatial and temporal resolution of the reconstructed image after acquisition, thereby providing adaptive reconstruction of images without the need to acquire new data.

A method for displaying image data from a medical image scanner using a computer system having a display, the method comprising acts of:
- presenting, to a user in the display of the computer, a user interface;
- receiving, via the user interface, a selection of user-defined parameters for constructing a reconstructed image, wherein the selection of user-defined parameters further includes at least one of a spatial distribution and a temporal distribution parameters;
- receiving and saving a plurality of intermediate images in a standard format, the plurality of intermediate images acquired from the medical image scanner;
- and
- retrieving and reconstructing the reconstructed image by aggregating a set of the plurality of the intermediate images, the set corresponding to the user-defined parameters.
A system for displaying image data for reconstruction of images from a medical image scanner, the system comprising:
- a user interface configured to be presented, to a user in a display, and configured to receive a selection of user-defined parameters for constructing a reconstructed image, the selection of user-defined parameters further includes at least one of spatial distribution parameters and temporal distribution parameters;
- a processor, coupled to the user interface, and configured to:
- receive and save a plurality of intermediate images in a standard format, the plurality of intermediate images are acquired from the medical image scanner;
- and
- retrieve and reconstruct the reconstructed image by aggregating a set of the plurality of the intermediate images, the set corresponding to the user-defined parameters;
- and
- a storage medium coupled to the processor, configured to store the plurality of intermediate images.
