摘要:
Banding artifacts in steady state free precession (SSFP) magnetic resonance imaging (MRI) are reduced by acquiring and combining multiple SSFP images in an augmented matrix where an acquisition vector in k-space is equal to a Fourier matrix of the trajectory on a known distortion operator for each trajectory in k-space.

The phase background of a proton resonance frequency shift treatment image may be estimated by fitting a combination of baseline images to the treatment image.

A method for enhancing resolution and contrast in an MRI image is provided. A transient signal acquisition is applied to acquire a plurality of samples of data, comprising reducing transient signal oscillations and acquiring a plurality of MRI samples of data. Transient signal compensation is applied to the plurality of samples of data to provide data with signal compensation. A noise reduction technique is applied to the data with signal compensation. Data resulting from the applying the noise reduction is used to generate an MRI image.
摘要:
Provided are a medical information importer and method for importing medical information into a network-accessible database. The medical information importer includes a housing includes with an external stand-alone form factor, the housing including an interface for receiving a portable computer-readable medium storing medical information. An information reading component is provided for reading the medical information from the portable computer-readable medium when operatively connected to the interface. A computer-readable memory in communication with the information reading component stores, at least temporarily, the medical information read by the reading component under the direction of a controller. And a network interface connects the medical information importer to a communication network without a local connection between the medical information importer and a computer terminal including a display device for viewing the medical information.
