Abstract: A method for artifact correction in computed tomography, the method comprising: (1) acquiring a plurality of data sets associated with different X-ray energies (i.e., D1, D2, D3 . . . Dn); (2) generating a plurality of preliminary images from the different energy data sets acquired in Step (1) (i.e., I1, I2, I3 . . . In); (3) using a mathematical function to operate on the preliminary images generated in Step (2) to identify the sources of the image artifact (i.e., the artifact source image, or ASI, where ASI=f(I1, I2, I3 . . . In)); (4) forward projecting the ASI to produce ASD=fp(ASI); (5) selecting and combining the original data sets D1, D2, D3 . . . Dn in order to produce a new subset of the data associated with the artifact, whereby to produce the artifact reduced data, or ARD, where ARD=f(ASD, D1, D2, D3 . . . Dn); (6) generating a repaired data set (RpD) to keep low-energy data in artifact-free data and introduce high-energy data in regions impacted by the artifact, where RpD=f(ARD, D1, D2, D3 . . .

Abstract: The present invention generally relates to an illuminatable jewelry system having a jewelry element containing a controllable light source. By way of example, the jewelry element may be transparent or translucent. The jewelry may also have other types of decorative elements attached to a length of conductive jewelry wire. A power cell having a solar cell, an energy harvesting circuit and a rechargeable battery are in electronic communication with the light source. Magnetic connectors permit the illuminatable jewelry system to be worn and operate to complete an electrical circuit between the power cell and the light source.

Abstract: A method for artifact correction in computed tomography, the method including: (1) acquiring a plurality of data sets associated with at least one low X-ray energy, and at least one high X-ray energy; (2) generating a plurality of preliminary images from the plurality of data sets; (3) identifying sources of an artifact source image; (4) forward projecting the artifact source image to produce artifact source data; (5) selecting and combining the plurality of data sets acquired in order to produce a new subset of data associated with the artifact, whereby to produce artifact reduced data; (6) generating a repaired data set to keep data sets associated with the low X-ray energy in artifact-free data and to introduce data sets associated with the high X-ray energy in regions impacted by an artifact; and (7) generating a final reduced artifact image from the repaired data set.
