چکیده

complex shape variability evident in intersubject ̄ oanatomies can be accommodated using GrenanGlobal Shape models. Following the approach of :, 3, 4], we construct a digitized textbook containall of the information currently available about a :al neuroanatomy on a fixed 3D coordinate system. textbook contains anatomical information (mag: resonance images, cryosection blockfaces, etc...) symbolic information (structure names, functions, ̄ actions with other structures, etc...). The textanatomy is individualized by deforming the shape .1atomic atlas images to match corresponding irafrom an individual. Symbolic information in the ~ook is then deformed and projected onto the inlual’s anatomy using the same estimated trans.ation. In addition, functional information such ~sitron emission tomography (PET) images in the .~ individual can be mapped back to the textbook omy using the inverse transformation. By removhe individual shape variability from functional imthe relationship between function and anatomy ~s a normal population can be delineated. Once ocation of normal function is established, abhorties associated with disease states can be detected.

Magnetic resonance elastography using 3D gradient echo measurements of steady-state motion.

Magnetic resonance elastography (MRE) is an important new method used to measure the elasticity or stiffness of tissues in vivo. While there are many possible applications of MRE, breast cancer detection and classification is currently the most common. Several groups have been developing methods based on MR and ultrasound (US). MR or US is used to estimate the displacements produced by either q...

Three-dimensional subzone-based reconstruction algorithm for MR elastography.

Accurate characterization of harmonic tissue motion for realistic tissue geometries and property distributions requires knowledge of the full three-dimensional displacement field because of the asymmetric nature of both the boundaries of the tissue domain and the location of internal mechanical heterogeneities. The implications of this for magnetic resonance elastography (MRE) are twofold. Firs...

Meshless deformable models for 3D cardiac motion and strain analysis from tagged MRI.

Tagged magnetic resonance imaging (TMRI) provides a direct and noninvasive way to visualize the in-wall deformation of the myocardium. Due to the through-plane motion, the tracking of 3D trajectories of the material points and the computation of 3D strain field call for the necessity of building 3D cardiac deformable models. The intersections of three stacks of orthogonal tagging planes are mat...
