Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A nuclear camera is provided with an open and flexible software architecture which enables users to readily understand, modify, and exchange data files. In a constructed embodiment the software architecture utilizes xml files which can be defined and read by a user using readily available tools and viewers. Both control data and image data can be formatted in this manner. An illustrated software architecture contains a directory of manufacturer-supplied xml control files, and a directory of user modified or created xml control files. This software architecture enables users to exchange protocol and image information over conventional communications networks such as the Internet.

Abstract: A gamma camera system is described in which multiple simultaneous acquisitions are performed based upon different characteristics for event data acquired by a common gantry behavior. The event data from a detector is selected for different images based upon characteristics such as gating, ungated, energy windows, or zooming.

Abstract: A gamma camera is provided in which the study protocol can be modified after the study has commenced and while event data is being acquired. In such a camera, study parameters such as the duration of the study, the number of image frames acquired, or the count criterion required to produce an image may be changed dynamically as the study proceeds. Thus, a nuclear study which is seen to be leading to unsatisfactory or less than optimal results may be altered during acquisition to increase the likelihood that diagnostically useful results will be produced.

Abstract: A gamma camera system is described in which counts are scatter corrected using multiple windows located in the vicinity of a photopeak. Pixel data is thereby scatter corrected prior to image formation. The system is useful-in nuclear medicine studies using dual isotopes such as stress and lung perfusion studies, wherein count data of the multiple isotopes are acquired simultaneously.
