Abstract: An ultrasonic imaging system and method for imaging human or animal tissue having a surface and including a probe comprising a platen for defining the surface in a manner supporting the human or animal tissue for imaging the same, a transducer positioned closely adjacent the supporting platen for providing an output ultrasonic beam directed on the surface so that the size of the beam at its focal point is as small as possible to maximize the resolution of the system an electrically operated motor for moving the transducer in a manner such that the ultrasonic beam is directed in a path along the surface. A fluid-tight housing extends from the tissue-supporting surface and has an interior region containing the transducer and motor which region is filled by an electrically non-conductive fluid having an acoustic impedance substantially equal to that of water and having a viscosity sufficiently low so as not to impede the movement of the transducer.

Abstract: An improved X-ray monochromatizing subassembly, method and system are provided by a plurality of X-ray dispersive structures which are spaced and aligned to intercept X-rays and reflect monochromatized X-rays from the intercepted X-rays. The system includes a source of X-rays and an X-ray detector for detecting the monochromatized reflected X-rays. The monochromatized X-rays can be designed to be diverging, parallel or converging and can be designed for a particular wavelength of interest.

Abstract: Point source X-ray focusing device structures, materials and methods of forming them are provided which exhibit a greatly increased total reflected intensity for a desired X-ray wavelength of interest. The devices include one or more focusing elements which each have a focusing surface with a plurality of layer pairs formed thereon. The focusing surface and the layer pairs are designed to collect, reflect and concentrate the maximum X-ray flux from a point source to a focus point for a particular wavelength of interest.

Abstract: Apparatus for producing microform records from hard copy or a cathode ray tube image or the like fed from a selected data source, includes an image-reducing projection system into which is selectively directed light reflected from hard copy or light from the face of a remote cathode ray tube to which white background CRT image-forming signals are fed. The reduced image involved is preferably applied first to a non-archival heat developable mask-forming film, like a dry silver film, and then the image on this film is transferred preferably to an archival film capable of later receiving additional data on unused portions thereof and most advantageously arranged as a microfiche card. A cathode ray tube smaller than the hard copy is positioned below but in spaced relation to a hard copy receiving platform-containing or receiving image field area.

Abstract: A device for flash imaging, through an imaging mask at an imaging film plane, a dry-process imaging film having a layer of an energy dispersible image forming material on a surface thereof. The device comprises a solid, electromagnetic energy transmitting body advantageously in the form of a quartz prism having a generally frusto-pyramidal configuration. The energy transmitting body is associated with a source of electromagnetic energy, and acts to collect, direct, collimate and shape the energy emitted by the source to provide maximum utilization and substantially uniform distribution of the energy at the imaging film plane.

Abstract: An imaging device for flash imaging, through an imaging mask at an imaging film plane, a dry-process imaging film having a layer of an energy dispersible image forming material on a surface thereof. The device comprises electromagnetic energy collecting means which is associated with a source of electromagnetic energy. The energy collecting means includes an energy transmitting body which directs, collimates and shapes the electromagnetic energy emitted by the energy source. The energy collecting means also includes energy intercepting and reflecting members which form a chamber in which the energy source and the energy transmitting body are at least partially encased. A housing is provided for maintaining the energy transmitting body and the energy intercepting and reflecting members in a predetermined position with relation to one another, the energy source and the imaging mask at the imaging film plane.
