  • Publication number: 20190107637
    Abstract: Detector systems for enhanced radiographic imaging incorporate one or more Compton and nuclear medicine imaging, PET imaging, and x-ray CT imaging capabilities. The detector designs employ one or more layers of detector modules comprising edge-on or face-on detectors, or a combination of edge-on and face-on detectors, which can employ gas, scintillator, semiconductor, low temperature (such as Ge and superconductor) or structured detectors. The detectors implement tracking capabilities, and operate in non-coincidence or coincidence detection modes.

  • Patent number: 9384864
    Abstract: The invention provides methods and apparatus for detecting radiation including x-ray photon (including gamma ray photon) and particle radiation for dental x-ray imaging, radiation monitoring, and related industrial and scientific applications. Flat or shaped small (and small hybrid) area storage phosphor plates, available in multiple sizes, are encased in SP-carriers and used as detectors for intraoral dental x-ray imaging as a replacement for analog x-ray film and digital x-ray cameras, offering good detection efficiency, high spatial and contrast resolution, and a wide dynamic range. After removal of the SP-carrier, a small area storage phosphor plate is loaded into a dental storage phosphor scanner for readout. Intermediate and large area storage phosphor plates (including hybrid versions) are suitable for non-intraoral dental x-ray imaging. Suitable storage phosphors may be used in radiation monitoring, replacing current detectors employed in a film badge format.

  • Patent number: 9347893
    Abstract: The invention provides methods and apparatus for enhanced PCI and dual-use radiation imaging systems. In one implementation high resolution storage phosphor plate radiation detector (an area detector) is employed for conventional attenuation radiation imaging and/or PCI (including conventional PCI and coded aperture PCI). Slit and slot scan implementations for dual-use systems are introduced. Dedicated single and dual-use slit and slot scan system for conventional attenuation imaging and PCI are described that employ face-on or edge-on detectors. Slit and slot scan systems that employ area detectors are described. Edge-on, structured cell detector designs are described. Applications of edge-on structured cell detectors for CT, Nuclear Medicine, PET, and probe detectors are described.

  • Publication number: 20150242812
    Abstract: The invention provides a system for effectively implementing a patient's specific wishes (advance directives) regarding medical care even in a setting where the patient is incapacitated or is unable to communicate directly with care providers. In one implementation an Advance Directives portable combined identification unit device or equivalent device is employed to register and access a patient's wishes concerning limitations on health care measures to be applied when the patient is unresponsive. The patient's Advance Directives and identification material such as biometric information may be stored on a server (including the Cloud) or on a Personal Data Containment System device such as a RFID-enabled chip, a flash drive, a phone Application, etc. The Advance Directives information can be accessed by an automated code robot device which may result in alterations to protocol-driven medical procedures such as CPR and defibrillation.

  • Publication number: 20150077258
    Abstract: The invention provides an automated hand hygiene/infection control monitoring sensor-based system suitable for improving hand hygiene and multiple infection control measures and ensuring compliance by health care workers as well as visitors to hospitals and clinics. The use of biometric identification devices such as cameras for face recognition and profiling, microphones for voice recognition, etc. permit highly accurate identification without the use of removable identification devices such as identification badges which may include bar codes, magnetic strips or wireless devices such as RFIDS. Identification badges are removable and hence susceptible to being lost, misplaced, etc. Visitors are typically not assigned identification badges and hence enforcement of hand hygiene policies is minimal.
