摘要:
A method for generating a magnetic resonance image includes acquiring a first k-space data set from each of a plurality of RF coils. The first k-space data set includes calibration data and randomly undersampled data. For each RF coil, a fully randomly sampled k-space data set is generated by removing a portion of the calibration data. A compressed sensing reconstruction technique is applied to the fully randomly sampled k-space data set to generate an aliased image, which is used to generate a uniformly undersampled k-space data set. A second k-space data set is generated by inserting the portion of the calibration data and a parallel imaging reconstruction technique is applied to the second k-space data set to synthesize unacquired data. The second k-space data set and the synthesized data are combined to generate a complete k-space data set for the RF coil.

Disclosed is a roof safety anchor capable of permanent and watertight attachment to a roof. Installation of the roof safety anchor does not require the removal of roof shingles. The roof safety anchor captures a D-ring and a roof fastener between a base and a lid. The roof fastener extends through the base and a gasket to secure the roof safety anchor to the roof.

Disclosed is a base unit that may be used to demobilize a vehicle. The base unit may include a microprocessor, a relay connected to the microprocessor, and at least one transceiver connected to the microprocessor. In example embodiments, the microprocessor may be configured to receive data related to a number of time increments to count, count a number of time increments, and activate the relay when it determines that no more time is to be counted.

The present invention provides novel compositions of human IgG2 antibodies comprising a chelating agent. The present invention also provides novel antibody compositions that exhibit improved chemical and/or physical stability. Also provided are methods of treating diseases and conditions with compositions of human IgG2 antibodies, including inflammatory diseases and neoplasia disorders.
摘要:
Coil sensitivity of a receive coil to a gradient null location is measured and, from the measurements, a coil calibration value is determined and used to modify the MR data acquired with that receive coil to reduce the adverse effects of gradient nulling on MR images. Coil sensitivity values are determined for each coil of a coil array and the data for each coil is respectively weighted. An image that is substantially free of gradient null artifacts or ghosting is then reconstructed from the weighted data.

A woven pool cover fabric comprises a thermoplastic warp yarn and a thermoplastic fibrillated weft filling yarn, providing at least 95% shade. A woven swimming pool cover having polyolefin warp yarns and fibrillated polyolefin weft yarns is lightweight, water permeable, and provides at least % shade, thus preventing algae growth and debris accumulation in the pool, as well as facilitating ease of installation and removal of the cover.
摘要:
A solar panel installation tool, with coarse and fine position adjustment. The tool fits on a mounting rail installed on a roof, and supports the solar panel along its bottom side. A panel support bracket on the tool is adjusted to align the solar panel with the roof edge. The tool can be removed after the solar panel is bolted into place on the rack.
