  • Publication number: 20090211910
    Abstract: Dielectrophoretic (DEP) tweezers apparatus and methods for various applications, including particle trapping. Multiple electrodes (e.g., two or three) are disposed on or otherwise constitute an elongated object forming a tip. Exemplary electrode configurations include, but are not limited to, coaxial and triaxial arrangements. A voltage is applied across these electrodes to produce a non-uniform electromagnetic field proximate to the tip thereby creating a dielectrophoretic trap. Once trapped, a particle may be moved to desired locations via manipulation of the elongated object or the medium in which the particle is located. Multiple DEP tweezers apparatus may be arranged to form arrays of tips capable of respectively generating local electromagnetic fields confined to the tips. Such DEP arrays may be employed in nanofabrication processes involving nanolithography or nano-manipulation, as well as data storage and retrieval applications.

  • Patent number: 6956373
    Abstract: Systems and methods for producing multi-dimensional tissue characterization images are described. By combining colorized MRI images composited from multiple gray tone MRI images, riffle stacks can be formed and combined to render multidimensional reconstruction of anatomical, physiological and pathological features. Biophysical parameters are therefore automatically segmented, characterized, tagged, mapped and otherwise labeled. In another embodiment, gray tone images are collected by acquiring orthogonally opposed pulse sequences, the images of which are color masked and uniquely rendered in three dimensions to obtain voxels in which the color is determined by the summative color masks applied to original gray tone pixels. This method can be embodied as specific applications designed for the brain, abdomen, breast, pelvis, musculoskeletal and other organs and biophysical systems to facilitate diagnosis, surgical planning and virtual exploration.
