摘要： A foldable lens comprises an outer refractive surface portion comprising a first plurality of convexly curved refractive profile regions having positive optical power to converge light energy with refraction toward a focus on the retina. The convexly curved refractive profile regions of the outer region may correspond to at least about a quarter of the refractive power of the lens, such that the lens thickness is decreased substantially and the folded lens can fit through a small incision. The outer refractive surface portion focuses light with refraction, in focus images viewed through the outer portion of the lens can appear sharp to the patient. The outer refractive surface portion also comprises a second plurality of concavely curved refractive profile regions having negative optical power disposed between the first plurality, so as to diverge the light energy substantially away from the focus on the retina, such that visual artifacts are inhibited.

摘要： A magnetic resonance system uses a shielded superconducting magnet to produce a dsv useful for specialist imaging in an overall short magnet system at field strengths 1.5 Tesla and above. The magnet includes at least a first central coil C1, which has a length of at least 25% of the overall length of the magnet, and is used in concert with a series of symmetric primary coils, at least one set of which carry current in a direction opposite to that of the central coil. Force balancing is advantageously used in the design of the coils. The primary coils are shielded by at least one shielding coil, which carries current in a direction opposite to the majority of the primary coils. The magnet resonance system can be used for orthopedic imaging.

摘要： An intraocular lens for correcting or reducing the astigmatism of a cornea includes a pupil that is spatially divided into discrete zones, with each zone having a particular astigmatism magnitude and astigmatism orientation. In one embodiment, the zones all have the same astigmatism magnitude, which is equal and opposite the cornea astigmatism magnitude to within a particular tolerance, such as 0.25 diopters. In one embodiment, some or all of the zones all have different astigmatism orientations, with the angular separation between astigmatism orientations being on the order of the rotational misalignment tolerance of the lens to the cornea. The visual performance of such a lens deteriorates more slowly with rotational misalignment, when compared to a comparable lens having a uniform astigmatism orientation across its entire pupil, leading to more relaxed tolerances for a surgeon that implants the lens.

摘要： A multifocal diffractive lens comprises a multifocal diffractive structure coupled to a refractive component. The refractive component comprises at least one curved surface. The multifocal diffractive structure comprises a first plurality of substantially monofocal echellettes having a first optical power for near vision correction and a second plurality of substantially monofocal echellettes for far vision correction. The first plurality of substantially monofocal echellettes combined with the second plurality of substantially monofocal echellettes can provide a multifocal diffractive profile having decreased light scatter, chromatic aberration, and diffraction to non-viewing orders such that dysphotopsia is substantially inhibited. A third plurality of substantially monofocal echellettes having an intermediate optical power can be combined with the first plurality of substantially monofocal echellettes and the second plurality of substantially monofocal echellettes.

摘要： Asymmetric, compact superconducting magnets for magnetic resonance imaging are provided. The magnets have a homogeneous region (the “dsv”) which can be located close to one end of the magnet so as to reduce the sensation of claustrophobia experienced by patients undergoing MRI procedures. The magnets can be designed using a hybrid process in which current density analysis is performed to obtain an initial coil configuration which is then refined using non-linear optimization techniques to obtain a final coil configuration. The hybrid method can incorporate various constraints, including, the location and size of the dsv, the uniformity and strength of the B0 field, stray field strengths outside of the superconducting magnet, and field strengths within the magnet's coils. The hybrid technique can also be used to design compact symmetric superconducting magnets.
