Abstract: A method includes receiving k-space data corresponding to magnetic resonance data for a subject and selecting a template for analysis. In addition, the method includes generating an image using the k-space data and using the template.

Abstract: A magnetic resonance image is produced by shifting a gap during acquisition of spin data for a specimen. The spin data is generated by a gapped excitation sequence.

Abstract: A magnetic resonance image is produced by radial imaging using one or more preparatory pulses. The magnetic preparation pulse can include one or more adiabatic pulses.

Abstract: This document discloses, among other things, a system and method of creating a positive contrast magnetic resonance imaging (MRI) feature using a high transverse relaxation rate contrast agent.

Abstract: This document discloses, among other things, a method for removing a bullseye artifact from a radial image generated using magnetic resonance and using a swept frequency pulse.

Abstract: An anti-aliasing aperture and method of using the same is disclosed. In one embodiment, an anti-aliasing method includes passing light through an aperture stop, and diffracting the light passing through the aperture stop for spreading an image of a point object to cover more than a pixel on a detector array. The aperture stop includes two or more apertures. In another embodiment, an anti-aliasing apparatus includes an aperture stop having two or more apertures to diffract light passing therethrough and provide spreading of an image of a point object to cover more than one pixel on a detector array.

Abstract: An image sensing device including a package having opposing side portions, an imaging sensor having a top side portion, and a light selective element coupled to the opposing side portions and overlying the top side portion of the imaging sensor.

Abstract: A method of adjusting a portion of a dark frame in accordance with compensation values related to dark reference pixels of a picture frame to obtain an adjusted dark frame portion, and then subtracting the adjusted dark frame portion from a corresponding picture frame portion. The technique may be used to improve the accuracy of image sensors such as those used in digital cameras or video conferencing cameras by compensating for dark current noise. The technique may be applied to both CMOS image sensors and, in general, to any image sensors requiring dark frame subtraction. The techniques may also be used in conjunction with calibration of image sensors and imaging systems.

Abstract: In one embodiment, an anti-aliasing apparatus is disclosed. The anti-aliasing apparatus includes an aperture stop including an array of apertures. Each of the apertures on the aperture stop diffracts light passing therethrough and provides spreading of an image of a point object in a controlled image irradiance distribution. In another embodiment, an optical system is disclosed. The optical system includes a detector array having an array of pixels and an aperture stop positioned between an object plane and the detector array. The aperture stop includes an array of apertures, each of which diffracts light passing therethrough and provides a controlled spreading of the light to cover more than one pixel of the detector array.

Abstract: A spectral densitometer system reads dosimeter cards. The cards contain bar codes with information for calibration of the system and for identification of the cards (serial numbers for each card). The densitometer has compartments optically and physically separated by a mechanism which contains a slide for receiving the cards and moving them into alignment with openings which expose the bar code to a bar code scanner in one of the compartments. The compartment containing the scanner also contains a source of illumination which projects through another opening and through a radiation sensitive patch. A scanning spectrophotometer in the other compartment reads the spectrum of the transmitted illumination. The system includes a computer, which may be a separate host computer, connected to the spectrophotometer and the bar code reader via communication ports. The computer computes the dosage based upon the wavelength measurements and the calibration information contained in the bar code.
