20150351625 | PRISM PRESCRIPTION VALUE ACQUISITION SYSTEM, ACQUISITION METHOD, ACQUISITION APPARATUS AND PROGRAM FOR CORRECTING FIXATION DISPARITY - A prism prescription value acquisition system that includes a calculation part for numerically transforming a fixation disparity amount (unit: angle), which indicates a degree at which the visual axis is shifted from the central fovea of the retina when a subject conducts visual fixation of a target, into a prism prescription value by multiplying the fixation disparity amount by a coefficient when the fixation disparity amount is within ±4 minutes. Herein, the prism prescription value is calculated according to the following equation: AP | 12-10-2015 |

20090267945 | Visualization of Quantitative MRI Data by Quantitative Tissue Plot - In a magnetic resonance (MR) imaging display system, the values of at least two quantitative MR parameters for a given Region of Interest (ROI) are displayed and dynamically updated when the ROI is changed. | 10-29-2009 |
20100103166 | Method of Visualizing MR Images - In a method and a device MR images having various contrasts are scanned and then values for some or all of the parameters T | 04-29-2010 |
20100127704 | Method of Visualizing Segmented MR Images - A segmented MR image is provided by measuring a number of Magnetic Resonance Imaging parameters on an absolute scale. For example T1 relaxation, T2 relaxation and Proton Density PD can be measured on an absolute scale. The absolute values are then compared with known values for at least one type of tissue. For human tissue these parameters typically are in the order 300-4500 ms for T1, 50-1000 ms for T2 and 0-100% water for PD. Both T1 and T2 depend on the field strength. Based on a comparison between normal values for a particular type of tissue the values obtained for the image each pixel/voxel can be labeled with a certain probability that the voxel contains this type of tissue and segmented accordingly. | 05-27-2010 |
20110018537 | Interleaved Single Magnetic Resonance Sequence for MR Quantification - A magnetic resonance sequence includes an interleaved slice-selective pre-pulse and a slice-selective multi-echo acquisition. This sequence is repeated with different delays between the pre-pulse and the acquisition resulting in a matrix of complex images. Based on this matrix T1 and T2 relaxations, proton density and the B1 field can be estimated. These quantified parameters enable synthetic magnetic resonance imaging (MRI) and form a robust input for tissue segmentation in computer aided diagnosis for MRI. | 01-27-2011 |
