摘要： An optical motion sensing system (10) for use in imaging an anatomical structure employs an optical motion sensor (20) including a body contour conforming matrix ("BCCM") (30) and an optical fiber (40). Upon BCCM (30) being adjoined to the anatomical structure, BCCM (30) structurally conforms at least partially to a surface contour of the anatomical structure for reciprocating any motion by the anatomical structure. Optical fiber (40) is at least partially embedded in the BCCM (30) for generating an encoded optical signal (42) indicative of a shape of the optical fiber (40) responsive to any reciprocal motion by the BCCM (30) during an imaging of the anatomical structure. System (10) further employs a motion tracker (50) responsive to encoded optical signal (42) for periodically reconstructing the shape of optical fiber (40) with each change in the shape of optical fiber (40) representing motion by the anatomical structure.

摘要： Magnetic resonance (MR) spins are inverted by applying an inversion recovery (IR) radio frequency pulse (50). MR signals are acquired at an inversion time (TI) after the IR radio frequency pulse. TI is selected such that a first tissue of interest (e.g., blood) exhibits negative magnetism excited by the IR radio frequency pulse and a second tissue (e.g., intraplaque hemorrhage tissue) exhibits positive magnetism excited by the IR radio frequency pulse. The acquired magnetic resonance signals are reconstructed to generate spatial pixels or voxels wherein positive pixel or voxel values indicate spatial locations of positive magnetism and negative pixel or voxel values indicates spatial locations of negative magnetism. A first image (28) representative of the first tissue is generated from spatial pixels or voxels having negative signal intensities, and a second image (26) representative of the second tissue is generated from spatial pixels or voxels having positive signal intensities.

摘要： This disclosure relates to techniques for magnetic resonance (MR) image reconstruction. A herein-described k-space dictionary learning (KDL) technique and a herein-described dual space dictionary learning (DSDL) technique can use dictionaries to approximate an image and/or a data matrix in a signal observation domain for MR imaging by a weighted sum of dictionary entries. A herein-described self-supporting tailored k-space estimation for parallel imaging (STEP) technique can use k-space partitioning and basis selection tailored procedures to promote a spatially variant signal subspace and incorporation into a self-supporting structured low rank model that enforces locality, sparsity, and rank deficiency properties. The model can be formulated into a constrained optimization problem solvable by an iterative algorithm.

摘要： An improved motion-sensitization driven equilibrium (iMSDE) sequence based upon an MLEV-4 sequence is used for black-blood vessel wall imaging. The MSDE pulse pattern that is used as a preparation sequence for other procedures employed to acquire images has been modified to produce the iMSDE sequence by the addition of a second 180 degree refocusing pulse and two motion sensitization gradients. The iMSDE sequence thus includes a group of four radio frequency (RF) pulses, as well as additional magnetic gradient pulses that are not included in the conventional MSDE sequence. Computer simulations indicate that this new pulse sequence is substantially more immune to local B1 inhomogeneity than conventional sequences. In vivo experiments have demonstrated significant signal improvement at high first-order moments (m 1 ) conditions compared to the traditional MSDE sequence.
