Disclosed herein is a system and method for decreasing gradient field pulse sequence duration and reducing peripheral nerve stimulation with known gradient pulse areas for a magnetic resonance imaging system. The method comprising: receiving a first desired area corresponding to a first pulse; obtaining a second desired area corresponding to a second pulse; selecting the first pulse as a nested pulse if the first desired area is smaller than the second desired area, and establishing the second pulse as a nesting pulse, otherwise selecting the second pulse as the nested pulse and establishing the first pulse as the nesting pulse. The method also includes: determining an amplitude and pulse duration for the nested pulse and ascertaining an amplitude and pulse duration for the nesting pulse. Finally, the method includes arranging a plurality of gradient field pulse sequences to include the nested pulse and the nesting pulse.

An annular beveled insert for enhancing the insertion of a plain end of a pipe into a mating belled end of a pipe, the insert including an annular main body portion having a substantially flat surface and a beveled opposed surface. The annular main body portion has inner and outer diameters approximately equal to inner and outer diameters, respectively, of the plain end of the pipe. An outwardly directed flange extends from the annular main body portion around a periphery and has an outer diameter greater than the outer diameter of the plain end of the pipe. The flange is sufficiently flexible so that it bends into an angle of approximately ninety degrees with the flat surface of the annular main body portion and aids the main body portion in masking the plain end of the pipe as it passes through the annular gasket.

The apparatus and method alters the intravenous delivery of pharmaceuticals to enhance imaging of the vasculature of an animal. The apparatus includes a pressure-inducing component that is sized to attach circumferentially to an extremity of an animal thereby impeding arterial blood flow causing said pharmaceuticals to remain at selected levels within the vasculature.

A non-invasive body worn computing platform is capable of long term unattended operation to capture, analyze, store, biosensor data and communicate health and system events, ECG waves and other biomedical data from the patient recorded, produced, or analyzed. The non-invasive body worn computing platform operates as a node within a wireless distributed collaborative network. The body worn computing platform has a latch-able mechanical and electrical interface for rapid swapping of the device and power source to and from biosensors, body harness, and power sources.

A method of generating a magnetic resonance image is provided, comprising subjecting a subject to a magnetic field. The subject comprised of a first tissue a second tissue and a third tissue. The method generates a first pulse sequence at a first TI time and generates a first image after the first pulse sequence. The first image has a first image first tissue magnitude, a first image second tissue magnitude, and a first image third tissue magnitude. The method then generates a second pulse sequence at a second TI time and generates a second image after the second pulse sequence. The second image has a second image first tissue magnitude, a second image second tissue magnitude, and a second image third tissue magnitude. Finally, the method generates a resultant image by combining the first image and the second image. The first image first tissue magnitude and the second image first tissue magnitude combine to form a positive resultant first tissue magnitude. The first image third tissue magnitude and the second image third tissue magnitude combine to form a negative resultant image third tissue magnitude.

A repaired pipeline includes an A/C pipe segment having an end, a repair segment having an end and a repair coupling coupling the A/C pipe segment to the repair segment. An A/C pipe containment cap includes an annular end having a width slightly larger than a thickness of the A/C pipe segment, an outer diameter side wall extending perpendicularly from an outer edge of the annular end, and an inner diameter side wall extending perpendicularly from an inner edge of the annular end. The containment cap is mounted on the end of the A/C pipe with the inner diameter side wall and the outer diameter sidewall extending longitudinally along an inside surface and an outside surface of the A/C pipe, respectively, and the annular end engaging the end of the A/C pipe.

摘要:
A cap for use in dispensing viscous liquids from containers without the accompaniment of lower viscosity liquid present in the container. The cap has a top portion with an outside surface and an inside surface and an elongated conduit formed at a pre-determined angle. The elongated conduit has an outlet and an inlet. The outlet is situated either eccentrically or concentrically on the outside surface of the top portion such that at least one point on the circumference of the top portion is greater than 10 millimeters from the edge of the inlet.

The present invention discloses a modular MRI imaging system. The imaging system includes MRI radio-frequency antenna arrays separate from the patient support structure. The antenna arrays are affixed to a thin, flexible film such that they may be located next to the anatomical region of interest. In addition, multiple antenna arrays may be configured in various planar or three-dimensional arrangements to optimize the FOV and SNR. Separate patient support structures are provided that enhance ergonomics and patient stabilization. By removing the antenna from the housing, the support structures may be designed without the constraints of supporting the antenna or the associated electronics. The MRI imaging system further employs a preamplifier module. The preamplifier module houses the preamplifier and much of the other associated circuitry for each of the antennae. The preamplifier module operates to combine the signals from the antenna arrays and pass the signals to the MRI system.
