Intraoral three-dimensional (3D) tomosynthesis imaging systems, methods, and non-transitory computer readable media are used to generate one or more two-dimensional (2D) x-ray projection images and to reconstruct, using a computing platform, the one or more 2D x-ray projection images into one or more 3D images of an object, such as teeth of a patient, which can then be displayed on a monitor in order to enhance diagnostic accuracy of dental disease. The intraoral 3D tomosynthesis imaging system can include a wall-mountable control unit connected to one end of an articulating arm, the other end of which is connected to an x-ray source, which is configured to generate x-ray radiation that is acquired by an x-ray detector held at a desired position by an x-ray detector holder that is removably coupled to a collimator at an emission region of the x-ray source.

Various methods and systems are provided for a set of devices for an imaging system. In one example, the set of devices includes a first device configured to obtain a first set of image data and a second device configured to obtain a second set of image data along at least one dimension. The first and second sets of data may be compiled to generate a field-of-view (FOV) preview.

Methods and systems are provided for dynamically visualizing an object of interest that includes part of the vasculature of a patient, which employ a 3D model of the object to generate at least one roadmap that includes information that characterizes properties of the object (such as centerlines, contours, and an image mask. Reference location(s) corresponding to the roadmap(s) are determined for an interventional device used to treat the object. In an online phase, non-contrast-enhanced x-ray image data of the object are obtained and processed to determine location of the interventional device in the image data, and a particular roadmap is selected or accessed. The reference location corresponding to the particular roadmap and the determined location of interventional device are used to transform the particular roadmap. A visual representation of the transformed roadmap is overlaid on the image data for display.

According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, a diaphragm mechanism, an X-ray detector, image generating circuitry, a display, a first interface, a second interface, and processing circuitry. The processing circuitry controls the diaphragm mechanism and the X-ray tube according to the operation to the first interface so that the X-rays are radiated to a first radiation range, and controls the diaphragm mechanism and the X-ray tube according to the operation to the second interface so that the X-rays are radiated to a second radiation range. The processing circuitry controls the display so that the first display area displays the X-ray images sequentially generated according to radiation of the X-rays, in parallel with the radiation.

A radiation detector that generates and outputs image data representing a radiographic image corresponding to emitted radiation, and up and down directions of the radiation detector are set in advance with respect to top and bottom directions of the radiographic image, a detection unit that detects at least one direction of the up or down directions of the radiation detector, and a display unit that is provided in a housing for accommodating the radiation detector and displays direction information representing the at least one direction of the up and down directions of the radiation detector detected by the detection unit are included.

A radiography system is provided such that a plurality of portable information terminals are associated with a radiation detecting unit so as to be managed by a processing unit. This improves portability and facilitates management including a change of association. The radiography system includes a radiation detecting unit arranged to detect radiation, a plurality of portable information terminals allowed to be associated with the radiation detecting unit, and a processing unit configured to receive and process radiographic image data detected by the radiation detecting unit and transmit the processed radiographic image data to the portable information terminal associated with the radiation detecting unit.

A CPU and an FPGA of the imaging control device receive first identification information and a preparation completion signal indicating that preparation for receiving radiation has been completed from a radiation detector and transmit the first identification information and irradiation conditions of the radiation associated with the first identification information to a radiation generation unit. Then, the CPU and the FPGA receive, from the radiation generation unit, second identification information copied from the first identification information by the radiation generation unit in a case in which irradiation with radiation has succeeded. Then, the CPU and the FPGA collate the first identification information and the second identification information, and determine whether or not to perform automatic brightness control, which sets a brightness level of the radiographic image to a prescribed level and updates the irradiation conditions on the basis of the radiographic image, according to a collation result.

An X-ray imaging system has an X-ray imaging apparatus include a foreign object image generation element that generates a foreign object image to make sure there is no foreign object left inside a subject body after a surgical operation. A first display unit displays at least one image selected from a group consisting of an X-ray image and a foreign object image. The X-ray imaging system is connected to an X-ray imaging apparatus through a network and displays the foreign object image on the second display unit that provides a better visual recognition level than the first display unit.
