Abstract: An imaging system for imaging at least a first and a second subject has a support stage to support the subjects. An imaging system has an ionizing radiation imaging section with at least a first ionizing radiation source for directing ionizing radiation within a first zone that includes the first subject and a second ionizing radiation source for directing ionizing radiation within a second zone that lies substantially outside the first zone and that includes the second subject. At least one imaging receiver forms an image of the subject within each zone. A camera system obtains at least one image of the at least first and second subjects. A computer is in signal communication with the imaging system and energizable to form a combined image from two or more images of the same subjects.

Abstract: An imaging system and method for imaging an immobilized object. The imaging system includes a support member adapted to receive the object in an immobilized state. The system also includes means for imaging the immobilized object in various imaging modes to capture images of the object. The imaging system further includes a movable phosphor screen. The phosphor screen is adapted to be movable without moving the immobilized object and support member.

Abstract: An imaging system and method for imaging an immobilized object. The imaging system includes a support member adapted to receive the object in an immobilized state. The system also includes first means for imaging the immobilized object in a first imaging mode to capture a first image, and second means for imaging the immobilized object in a second imaging mode to capture a second image. The first imaging mode is selected from the group: x-ray mode and radio isotopic mode. The second imaging mode is selected from the group: bright-field mode and dark-field mode. The first and second means for imaging may be included in a capture system having a camera, a first mirror on a first side of the support member for reflecting light to capture the first and second images and a second mirror on a second, opposite side of the support member for reflecting light to capture a third image from an opposite side of the object.

Abstract: A method for forming a sequence of images of a subject obtains at least first and second image sets of the subject, each image set having a given angular displacement relative to an axis of rotation of the subject, each image set having at least a first component image of a first diagnostic modality at the given angular displacement and a second component image that is co-registered to the first component image at the given angular displacement. The first image set is selected as the selected image set for display. A synthesized image is formed by combining image data for the at least first and second component images of the selected image set and the synthesized image is displayed.

Abstract: A tunable spectral filtration device comprises at least one optical filter for intersecting a first path of converging or diverging light comprising an axis at a first angle of incidence and at least one device positioned to enable a second path of the converging or diverging light to pass through the at least one optical filter at a second angle of incidence. The optical filter comprises at least one coating and is tiltable over a plurality of angles with respect to the axis. The first angle of incidence is opposite in sign to the second angle of incidence, such that the positioning of the at least one optical filter and the at least one device substantially cancels angle-of-incidence dependent spectral broadening and/or polarization dependent spectral broadening of the converging or diverging light.

Abstract: An optical modulator which has substantially low loss and has an improvement in voltage reduction is disclosed having an electro-optic lithium niobate substrate. The substrate has first, second and third ridges extending along its surface. Extending along the first and second ridges are first and second waveguides. A first RF electrode extends over the first waveguide and a second slotted electrode including a first section extends over the second waveguide. A second section of the slotted extends parallel to and adjacent to the first section on the third ridge. In summary, this invention provides a slotted ground electrode wherein a slot is formed in the substrate between the slotted electrode.

Abstract: Methods of the invention include fluorescence microscopy inspection of an imaged resist layer prior to any type of development processing. Preferred resists for use in the methods of the invention contain a component that facilitates monitoring of a resist coating layer, particularly a component that can function as a proton acceptor and have a change in fluorescence upon exposure to radiation reemployed to pattern an image in the resist coating layer.

Abstract: A method of imaging acid in a chemically amplified photoresist comprising the steps of: (a) exposing the chemically amplified photoresist to radiation thereby generating an acid, the chemically amplified photoresist comprising at least one species of pH-dependent fluorophore that fluoresces in the presence of the acid, the pH-dependent fluorophore being present at a concentration that enables the fluorescence from individual molecules of the pH-dependent fluorophore to be individually resolved; and (b) generating an image of the acid in the photoresist, the image comprising at least one or a plurality of discrete points corresponding to the fluorescent emission from an individual molecule or molecules of the pH-dependent fluorophore.

Abstract: A laser source attached to an ophthalmic observation instrument, such as a fundus camera, projects a spot, and a light collector is positioned in the image field of the instrument over the spot to collect return light scattered from a homogeneous tissue bed in the image field. The collected light is directed onto a photomultiplier and digitized at a sampling rate above several kHz to provide a continuous data stream which is fed to a process/control module that operates to automatically define a number n of sample intervals, select a subset of the sample intervals for analysis, transform the selected intervals, and evaluate the shape of the transformed sample intervals. The process/control module may be implemented on a simple computer, and include a user interface which indicates status of signal acquisition, selection and evaluation during a short, e.g., one-minute illumination interval.
