Abstract: A method for determining a concentration of a contrast agent in imaging data includes calculating a pre-contrast attenuation map of a region of interest of a patient. Following an administering of a contrast agent to the patient, a post-contrast attenuation map of the region of interest of the patient is calculated. An increase in attenuation value is determined based on the pre-contrast attenuation map and the post-contrast attenuation map and a contrast agent concentration map is calculated for the region of interest based on the increase in attenuation value.

Abstract: In a method to correct noise effects in magnetic resonance (MR) images, which is executed in a processor (computer), the processor executes a fitting algorithm in order to calculate initial values for each of selected variables in signal model that models noise effects in a modeled, noise-containing MR image. The processor then iteratively executes the same or a different fitting algorithm, in order to generate final values for each of the selected variables. The processor is provided with an actual, acquired MR image that contains noise, and the processor uses the final values of the selected variables to calculate synthetic signal intensities in the MR image, thereby producing a synthetic MR image with no noise bias effects of errors. This synthetic image is made available in electronic form at an output of the processor, as a data file.

Abstract: A computer-implemented method for concurrently estimating the amount of fat and iron in anatomical tissue from magnetic resonance (MR) signal data includes receiving a test signal representative of the anatomical tissue acquired using a MR pulse sequence type. A repository of reference signal data is generated. The repository comprises a plurality of reference signals derived by an MR signal simulation for a plurality of different transverse relaxation rates, a plurality of different fat fractions, and the MR pulse sequence type. A first reference signal is identified in the plurality of reference signals. The first reference signal provides a best match to the test signal based on one or more matching criteria. The repository is searched to determine a first transverse relaxation rate and a first fat fraction associated with the first reference signal. Then, the amount of fat and iron in the anatomical tissue is estimated based on the first transverse relaxation rate and the first fat fraction.

Abstract: A shelf device comprises an enclosed frame that includes a plurality of members, a concealed compartment within the frame, and a locking system that includes a locking mechanism comprising a slide bolt and magnetic lift positioned perpendicularly within the slide bolt, a ledge that is engaged with the slide bolt when the locking system is locked, and a magnet. The magnetic lift moves in one direction to cause the slide bolt to move perpendicularly to the magnetic lift's direction as the slide bolt disengages or engages with the ledge to unlock or lock the shelf, respectively. In one embodiment, a rare earth magnet is aligned with the magnetic lift to pull the magnetic lift vertically upward causing the slide bolt to move horizontally backward to disengage the slide bolt from the ledge. Consequently, the shelf is opened as one or more frame members are released to expose the concealed compartment.
