A system and method for ablation planning includes defining (502) shapes and sizes for one or more ablation volumes based on probability of treatment, and determining (510) a target volume to be treated. A procedure plan is provided (516) by determining a number and location of planned ablations within the target volume using the one or more ablation volumes. A joint probability distribution (520) is determined for at least two planned ablations in the target volume. A final configuration is visualized (530) to determine if plan objectives are met based on a probability of treatment for the target volume.

A method for interventional navigation using 3D contrast-enhanced ultrasound (CEUS) imaging includes acquiring a reference 3D CEUS volume and tracking information during a useful lifetime of a contrast enhancement agent administered to the anatomy. Real-time tracked tissue images are acquired during the interventional procedure. In addition, a corresponding CEUS multiplanar reconstruction (MPR) for at least one of the acquired real-time tracked tissue images is generated. At least one of the acquired real-time tracked tissue images is displayed along with the corresponding CEUS MPR. The displayed real-time tracked tissue image includes at least an image of the instrument within the desired portion of the anatomy and the CEUS MPR corresponds to the displayed real-time tracked tissue image. Thus, the contrast enhanced image information and tissue image information are concurrently display for the interventional navigation at least subsequent to the expiration of the contrast enhancement useful lifetime.

In a method of making a monolithic elongated nanowire, a mask polymer layer is applied to a selected crystal surface of a seed crystal. A plurality of spaced apart elongated openings is defined through the mask polymer layer, thereby exposing a corresponding plurality of portions of the crystal surface. The openings are disposed so as to be aligned with and parallel to a selected crystal axis of the seed crystal. The portions of the crystal surface are subjected to a chemical nutrient environment that causes crystalline material to grow from the plurality of portions for at least a period of time so that monocrystalline members grow from the elongated openings and until the monocrystalline members laterally expand so that each monocrystalline member grows into and merges with an adjacent one of the monocrystalline members, thereby forming a monolithic elongated nanowire.

A 3D ultrasound image from a memory (20) is compared with a 3D diagnostic image from a memory (12) by a localizer and registration unit (30) which determines a baseline transform (Tbase) which registers the 3D diagnostic and ultrasound volume images. The target region continues to be examined by an ultrasound scanner (22) which generates a series of real-time 2D or 3D ultrasound or other lower resolution images. The localizer and registration unit (30) compares one or a group of the 2D ultrasound images with the 3D ultrasound image to determine a motion correction transform (Tmotion). An image adjustment processor or program (32) operates on the 3D diagnostic volume image with the baseline transform (Tbase) and the motion correction transform (Tmotion), to generate a motion corrected image that is displayed on an appropriate display (74).
摘要:
A nanopore sensor comprises second electrophoresis electrode or micropump, second fluidic reservoir, second micro-nanometer separation channel, substrate, sub-nanometer-thick functional layer, first micro-nanometer separation channel, first electrophoresis electrode or micropump, and electrophoresis electrode or micropump that are sequentially assembled. An opening and a nanopore are provided through the substrate and the sub-nanometer-thick functional layer, respectively. A first electrode for measuring ionic current is provided in the first micro-nanometer separation channel, and a second electrode for measuring ionic current is provide in the second micro-nanometer separation channel. The present invention provides a simple method to prepare a sub-nanometer functional layer having a nanopore extending through the sub-nanometer-thick functional layer. The pore size is comparable to the spacing between two adjacent bases in a DNA strand required for single-base resolution sequencing. The shape of nanopore overcomes nucleotide conformation effect on the identification as bases translocate through the nanopore.

A washing machine for automatically adding the detergent by negative pressure comprises a water inlet, a detergent container and a tub. A main inflow waterway and a rinse waterway are provided between the water inlet and the tub. A dosing container which communicates with the detergent container is provided between the rinse waterway and the tub. A venturi tube is provided in the main inflow waterway. Due to venturi effect, the main inflow water stream becomes narrower and the water inflowing velocity is accelerated, so that a relative vacuum area which communicates with the dosing container is formed at the rear side of the venturi tube outlet, negative pressure is generated in the dosing container, and the detergent in the detergent container.

摘要:
An electric power generator includes a first conductive layer, a plurality of semiconducting piezoelectric nanostructures, a second conductive layer and a plurality of conductive nanostructures. The first conductive layer has a first surface from which the semiconducting piezoelectric nanostructures extend. The second conductive layer has a second surface and is parallel to the first conductive layer so that the second surface faces the first surface of the first conductive layer. The conductive nanostructures depend downwardly therefrom. The second conductive layer is spaced apart from the first conductive layer at a distance so that when a force is applied, the semiconducting piezoelectric nanostructures engage the conductive nanostructures so that the piezoelectric nanostructures bend, thereby generating a potential difference across the at semiconducting piezoelectric nanostructures and also thereby forming a Schottky barrier between the semiconducting piezoelectric nanostructures and the conductive nanostructures.
摘要:
A method (50) for quantitative 3D contrast enhanced ultrasound (CEUS) analysis includes acquiring (54) an initial pair of ultrasound contrast and tissue images of an anatomy. A region of interest (ROI) or volume of interest (VOI) is established (56) in the initial acquired tissue image, which becomes the baseline tissue image. The established ROI/VOI is automatically registered (58) from the initial tissue image to the initial contrast image, which becomes a baseline contrast image. Quantitative analysis is performed (60) on the ROI/VOI of the baseline contrast image. The method further includes acquiring (62) a next ultrasound contrast and tissue image pair, corresponding to an i th current contrast and tissue image pair. Frame-to-frame registration is established (64) between (i) the current tissue image and (ii) the baseline tissue image, the frame-to-frame registration being used (66) between the current tissue image and the baseline tissue image to transfer the ROI/VOI from (i) the baseline contrast image to (ii) the current contrast image, thereby creating a transformed ROI/VOI in the current contrast image. Quantitative analysis is then performed (68) on the transformed ROI/VOI of the current contrast image.
