  • Patent number: 7551720
    Abstract: An x-ray system comprises an x-ray tube, covered by a housing, which emits x-rays therefrom, and a receiver mounted within the x-ray tube housing. An electronic sensor receives the emitted x-rays, converts the received x-rays into electrical image data signals, and transmits the electrical image data signals to the receiver. An image processing unit processes the electrical image data signals received from the receiver.

  • Patent number: 7545913
    Abstract: A method of operating a digital x-ray system having a plurality of information processors, each information processor associated with a corresponding one of a plurality of operatories. The method includes detecting at least one image in response to at least one energy source emitting energy, while the energy source is associated with an extension arm which is positioned to serve a selected one of the operatories, and outputting an electrical image data signal representing the detected image. The method also includes detecting a position of the extension arm, and automatically routing the outputted electrical image data signal to the information processor associated with the selected operatory based on the detected position.

  • Patent number: 7501631
    Abstract: An electronic imaging sensor, which has an improved immunity to noise caused by unwanted x-rays, images an object by collecting charge carriers produced in the sensor when the object is exposed to x-rays. One or more shielding areas are formed proximate the sensor to capture or sweep away any undesirable charge carriers generated by the unwanted x-rays. The shielding areas extend deeper beneath the surface of the sensor than the depth at which the desired charge carriers corresponding to the object being imaged is collected. The shielding areas capture charge carriers formed by the unwanted x-rays, which penetrate into the sensor to a greater depth than the depth at which the. desired charge carriers are collected. In this way, the undesirable charge carriers are captured near the region where they are generated and before they migrate towards the surface where they can be collected and manifest as noise in the resulting image of the object.

  • Patent number: 7471761
    Abstract: A method of computing oral bone mineral density using a panoramic x-ray system. A reference phantom having a known density is provided. A digital panoramic image of a body part and the reference phantom is obtained by irradiating the body part and the reference phantom. The reference phantom is disposed in a location free from anatomical features and in the same scan line as the body part. A relationship is established between a region of the image corresponding to a portion of the body part and a region of the image corresponding to the reference phantom. Bone mineral density is calculated based upon the established relationship and the known density of the reference phantom.

  • Patent number: 7193219
    Abstract: An intraoral sensor includes a radiation sensitive sensor array, an event detection circuit, and a transmitter. The radiation sensitive sensor array includes a scintillator which converts x-rays into visible light radiation, and a plurality of pixels sensitive to visible light radiation to capture an image upon the presence of incident radiation. The event detection circuit includes a current sensing device and is configured to generate a triggering signal indicating the presence of radiation incident on the sensor array based upon the amount of electrical current drawn by the sensor array. The transmitter is adapted to transmit via a wireless link signals representing an image captured by the sensor array.

  • Patent number: 7171181
    Abstract: An automatic frequency tuning (AFT) system which can effect immediate and accurate automatic frequency tuning of the local oscillator (LO) of a receiver, in order to achieve a stable intermediate frequency (IF) signal while reducing the power consumption and the cost of the system. In the automatic frequency tuning (AFT) system, an analog-to-digital converter (ADC) converts the intermediate frequency (IF) to a digital value which is sent to a microcontroller. A signal sent from the microcontroller accurately and automatically tunes the local oscillator (LO).

  • Publication number: 20060193436
    Abstract: A system for capturing multiple intraoral images includes an intraoral sensor. The sensor includes a sensor array, a transmitter and a power source that provides power to the sensor array and the transmitter. The sensor is configured to be inserted inside a patient's oral cavity, capture an image upon the presence of incident radiation and transmit from within the oral cavity via a wireless link electrical signals representing the image. A base station positioned outside the oral cavity is configured to receive the electrical signals transmitted from the sensor. The sensor is capable of capturing transmitting to the base station electrical signals representing multiple intraoral images without requiring that the sensor be removed from the patient's oral cavity.
