Abstract: A back illuminated sensor is included as a collector component of a detector for use in intraoral and extraoral 2D and 3D dental radiography, digital tomosynthesis, photon-counting computed tomography, positron emission tomography (PET), and single-photon emission computed tomography (SPECT). The disclosed imaging method includes one or more intraoral or extraoral emitters for emitting a low-dose gamma ray or x-ray beam through an examination area; and one or more intraoral or extraoral detectors for receiving the beam, each detector including a back illuminated sensor. Within the detector, the beam is converted into light and then focused and collected at a photocathode layer without passing through the wiring layer of the back illuminated sensor.

The bitterness suppressant includes one or more compounds selected from the group consisting of: a sugar selected from the group consisting of monosaccharide sugars, disaccharide sugars, polysaccharide sugars, and combinations of the any of the foregoing; sweet-tasting compounds; acids; amino acids; salts; miscellaneous suppressant substances; and combinations of any of the foregoing. The improved local anesthetic solution optionally includes one or more additional agents selected from the group consisting of: buffering agents; vasoconstrictors; preservative compounds; stabilizers; contrast media agents; and combinations of any of the foregoing.

Abstract: A microlens in radiography in providing healthcare services, including medical and dental fields. The microlens preferably is included as a component of a detector. The detector preferably comprises a converter, a plate, a filter, the microlens, and a collector including photosensitive areas. Low light images are received at the converter and transmitted directly or through the plate to the filter and then to the microlens. The microlens collects, refines and focuses the low light image that would have otherwise fallen onto the non-sensitive areas of the collector, thereby enabling low light detection efficiency at the sensitive areas, and thereby increasing the collector fill factor and quantum efficiency.

Abstract: The dental fluoroscopic imaging system includes a flat panel detector comprised by a gamma-rays or x-rays converter, a plate, a collector, a processing unit and a transmitter suitable for 2D intraoral/extraoral and 3D extraoral dental fluoroscopy. The x-ray converter contains a material capable of transforming the low dose gamma rays or x-rays beam received from an emitter after going through the dental examination area into electrical signals or a light image consequent with the radiographed image. The plate transmits the electric signals or light image to a collector which amplifies it and sends it to a processing unit and then to transmitter designed to transfer digital images sequentially to a host computer and software which can acquire, process, transform, record, freeze and enhance 2D and 3D images of video frame rates. Two dimensional images are obtained while using a C-arm/U-arm configuration while 3D images are obtained while using the O-arm configuration.

Abstract: A dental fluoroscopic imaging system includes a flat panel detector comprising a converter, a plate, a collector, a processing unit, and a transmitter suitable for 2D, intraoral dental fluoroscopy and for 3D extraoral dental fluoroscopy. The converter contains a material capable of transforming low dose radiation received from an emitter after going through the dental examination area into electrical signals. The plate transmits the electric signals to a collector, which amplifies the signals. The processing unit processes the signals into digital images, and the transmitter transfers digital images sequentially to a host computer having software that acquires, processes, transforms, records, freezes, and enhances 2D and 3D images, and compiles videos having video frame rates of between 3 and 100 frames per second. Two dimensional images and video are obtained using a single flat panel detector, while three dimensional images and video are obtained using two flat panel detectors.

Abstract: An apparatus for use in the field of dentistry consisting of a rotatable c-arm assembly having a housing with an emitter on one end and a fluoroscopic image receptor at another end, a control panel, three mechanical arms connecting the housing and the control panel to each other, an intraoral image receptor and a plastic holder device for the intraoral image receptor. The apparatus has the improved feature of having two modes of operation, a fluoroscopic mode or a conventional radiographic mode. The mode of operation is selected by the operator by a foot pedal for use in fluoroscopic mode, or a hand activator control for use in conventional mode. A beam of x-rays or gamma rays is emitted from the housing corresponding to the selected mode.
