Multiposition collimation devices and x-ray imaging systems, which include the multiposition collimation devices, are provided. The multiposition collimation device includes a collimator housing and a collimator plate constructed to at least partially block the passage of x-rays. The collimator plate is movable relative to the collimator housing to a first position, corresponding to a first x-ray detector size, and a second position, corresponding to a second x-ray detector size.

Multiposition collimation device and x-ray imaging systems

An adjustable mount for positioning an x-ray source comprising a vertical member that can swivel around a yaw axis, a circular arc-shaped yoke having two ends and passing through the vertical member, a gantry attached to the two ends of the yoke, and an x-ray source attached to the gantry. The x-ray source can be rotated around the yaw axis by swiveling the vertical member, pitched around a pitch axis by pitching the gantry, and/or rotated around a roll axis by passing the yoke through the vertical member. A method for x-ray imaging that includes centering an x-ray source at an aiming position within an adjustable mount, and aiming the centered x-ray source at an x-ray sensor by rotating the x-ray source around a roll axis of the adjustable mount. An x-ray source mounting system comprising an x-ray source and an adjustable mount to which the x-ray source is attached.

A dental positioning system and method employing the system are described. The system includes at least one receptor holder having an arm extending from a receptor grip. The receptor grip retains a receptor in a fixed position within the grip and with respect to the arm. The system also includes an alignment ring having a window formed therein and having at least one opening corresponding to the at least one receptor holder. The opening is constructed to receive the arm of the receptor holder such that the receptor is substantially centered with respect to the window.
