INTRAORAL X-RAY SYSTEM

An intraoral x-ray system mountable to a dentist’s office wall including components movable to compensate for defects in the wall’s flatness or the wall not being sufficiently perpendicular to the floor. The system also includes monitoring and compensation capabilities to compensate for drift in the position of the system’s x-ray source or patient movement before and during x-ray imaging, thereby avoiding the need for the taking of additional x-ray images and exposing the patient unnecessarily to extra x-ray dose. Additionally, the system further includes a data/signal processing unit that allows the x-ray source to be precisely moved along a predetermined trajectory and allows the system to perform computed tomosynthesis examinations of a patient. In addition, the x-ray source is attachable/detachable from the system’s robotic arm, with the system compensating automatically for the change in weight at the robotic arm’s end due to removal of the x-ray source.

The computing device may include at least one processor and at least one storage device. The method may include directing multiple dose sensors to detect a dose of radiation rays emitted from a radiation source of the imaging device. The multiple dose sensors may correspond to multiple imaging detectors, respectively. The method may also include determining the dose of the radiation rays. The method may further include directing, based on the dose of the radiation rays, at least one imaging detector of the multiple imaging detectors to proceed to detect the radiation rays for generating an image of a target object to be examined.

Multi-directional x-ray imaging system

An imaging system and methods including a gantry defining a bore and an imaging axis extending through the bore, and at least one support member that supports the gantry such that the imaging axis has a generally vertical orientation, where the gantry is displaceable with respect to the at least one support member in a generally vertical direction. The imaging system may be configured to obtain a vertical imaging scan (e.g., a helical x-ray CT scan), of a patient in a weight-bearing position. The gantry may be rotatable between a first position, in which the gantry is supported such that the imaging axis has a generally vertical orientation, and a second position, such that the imaging axis has a generally horizontal orientation. The gantry may be displaceable in a horizontal direction and the system may perform a horizontal scan of a patient or object positioned within the bore.

Source image distance adjustable X-ray imaging apparatus

A source image distance (SID) adjustable X-ray imaging apparatus is provided. The X-ray imaging apparatus may include an arm including a first end and a second end, a first X-ray component arranged at the first end of the arm, and a second X-ray component arranged at the second end of the arm. The first X-ray component and the second X-ray component may be opposite to each other. The first X-ray component may be configured to generate X-rays or receive X-rays. The first end may include a first weight balancing mechanism. When the first X-ray component moves with respect to the first weight balancing mechanism, the SID of the X-ray imaging apparatus may change but the first weight balancing mechanism may maintain a center of gravity of the first end unchanged.

RADIOGRAPHIC APPARATUS
20180000436 · 2018-01-04 · ·

A radiography apparatus is provided in which delays in it do not occur due to the influence of preliminary preparation of a radiation detector. The FPD 4 receives a signal from an X-ray tube control unit 6 and then completes preliminary preparation for the detection of radiation during accelerated movement of an X-ray tube 3 or the FPD 4. That is, the accelerated movement of the X-ray tube 3 or the FPD 4 and the preliminary preparation for the detection of radiation are carried out simultaneously. This enables imaging to be started immediately after the start of constant speed movement of the X-ray tube 3 or the FPD 4 without having to wait for constant speed movement thereof to start preliminary preparation of the FPD 4 as in conventional apparatuses. As a result, delays in imaging do not affect the radiation image.

X-RAY IMAGING DEVICE

Provided is an X-ray imaging device having a foldable arm unit for supporting an X-ray tube, and an operating unit for operating the X-ray tube, on a joint of arms constituting the arm unit. The operating unit is, for instance, a display unit serving also as the operating unit (display unit with a touch panel), and it is detachable from the joint of the arms. As another operating unit, a handle for operating the arm unit is provided. The handle for operating the arm unit can be provided with an operating switch for operating the X-ray tube. With this configuration, the X-ray imaging device being superior in operability and easy in checking the displayed information can be provided, at any height the X-ray tube is positioned.
