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.

Abstract: An apparatus and method for transferring data and power through an electromagnetic induction link is provided. The link operates with high efficiency to allow its use in scenarios with limited available power, such as with a computer's USB port. When data is transferred, redundant frequency encoded pulses are used. When power is transferred, a continuous waveform is used, and the-+transferred power may be used to provide power to a variety of devices and components and to recharge batteries.

Abstract: A dental camera is provided having multiple lenses. The dental camera has at least a first lens for use in an intra-oral mode, and at least a second lens for use in an extra-oral mode. The dental camera is switchable between the intra-oral mode and the extra-oral mode. Each lens is associated with an image sensor, for example, a CMOS active pixel sensor or a charge-coupled device.

Abstract: A dental camera is provided which is capable of operating in a wireless mode and a wired mode. A handpiece includes circuitry for generating a signal representing a video image and a first connector. A wireless adaptor module includes a power supply for supplying power to the handpiece, a transmitter for transmitting the signal representing a video image, and a second connector that mates with the first connector when the dental camera is being operated in the wireless mode. A cable has a third connector that mates with the first connector when the dental camera is being operated in the wired mode. With this system, clinical flexibility is afforded to a dental practitioner.

Abstract: A system for dental x-ray examinations includes an image receptor, and a holder removably bonded to the image receptor by an adhesive coating. The system for dental x-ray examinations provides the clinician with a greater freedom of positioning and thereby improves upon the effectiveness of x-ray examinations, as well as upon patient comfort.

Abstract: A method and apparatus for measuring bone density is disclosed. The method and apparatus use high-energy and low-energy images of hard-tissue and soft-tissue references to determine characteristics of hard and soft tissue under high-energy and low-energy radiation. Then, high-energy and low-energy x-ray images of the subject are processed to compute the density of the bone inside the subject.
