An X-ray imaging apparatus is provided with an X-ray irradiation unit, a detector, an image generation unit, an optical imaging unit for capturing an optical image, a storage unit for storing a trained model, the trained model being configured to output determination information to an input image based on the optical image, the determination information determining a state regarding an imaging range of a predetermined site of the subject or a relative position of the predetermined site to the other site of the subject, a control unit for acquiring the determination information, using the trained model, and a notification unit.

According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry designates a region of interest in a first tomogram among multiple tomograms which are based on tomosynthesis imaging performed with a subject compressed in a first direction. The processing circuitry specifies a second tomogram corresponding to the region of interest from among multiple tomograms which are based on tomosynthesis imaging performed with the subject compressed in a second direction different from the first direction.

A paralleling device that attaches to or is integrated with the backscatter shield of a handheld x-ray device. The paralleling device includes a number of ports that receive a rod and hold the rod in a fixed position. The rod is attached to an electronic sensor for use in oral and dental radiography. By fixedly attaching the electronic sensor and rod to the handheld x-ray device, the paralleling device allows dentists, hygienists and other dental assistants to easily configure and place the rod and electronic sensor in the patient's mouth without setting the handheld x-ray device down. The paralleling device also ensures that the electronic sensor and handheld x-ray device are at an appropriate angle relative to one another to allow for proper imaging of a patient's mouth.

An X-ray imaging system using multiple puked X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple puked X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

An imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject includes an optical camera that outputs an optical image by optically imaging a region including an irradiation field of the radiation applied to the subject from the radiation source, and at least one processor, in which the processor associates the optical image acquired by the optical camera with the radiation image on the basis of a timing signal transmitted from the radiation image detector side.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. A control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means Collision detection means provided in the source and sensor detect a possible collision of the source and/or sensor with the patient during the motion of the source and/or sensor and the control unit responds to such detected possible collision.

A lighting arrangement for a medical imaging system having a cylindrical wall that forms a tunnel that receives a patient to be scanned. The lighting arrangement includes a transparent wall section formed in the wall, wherein the transparent wall section extends along a transparent portion of a wall circumference. The imaging system also includes a lighting device located adjacent an outer surface of the transparent wall section. The lighting device extends along a device portion of a wall circumference corresponding to the transparent portion wherein light emitted by the lighting device is transmitted through the transparent wall section in a direction orthogonal to a longitudinal axis of the tunnel to circumferentially illuminate the tunnel. In addition, a system status is indicated by a color of light emitted by the LEDs. Further, light emitted by the lighting device varies in intensity to indicate a changing count rate.
