The application relates to an X-ray imaging unit for a medical imaging. The unit includes a rotating part with a first X-ray source and an X-ray imaging detector unit configured to provide an image with at least a rotational movement (R) around a rotation axis of the rotating part. The unit includes an upper shelf configured to enable the rotating part to move with respect to the upper shelf with a linear movement (L) and to be attached to a column with a pivoting joint for enabling a pivot movement (P) of the upper shelf around the column. The rotating part is configured to be positioned by the linear movement and the pivot movement during the imaging.

X-ray imaging unit for medical imaging

A method of automatically determining an imaging protocol. The method includes receiving, via a user-interface, a scan request. The scan request includes a region-of-interest definition. The method further includes determining, via a controller, an imaging protocol based on the scan request, and performing, via an imaging device, a scan of a patient based on the imaging protocol.

The application relates to an X-ray imaging unit () for X-ray imaging. The unit comprise a processor part (), a gantry part (), an X-ray source part () for emitting X-rays, and an X-ray imaging detector part () for receiving the X-rays from the source part. The gantry part comprises the source and detector parts. The processor part is configured to control the source and detector parts in order to obtain () an image data. The processor part is further configured to determine () at least one reference structure () of a patient () from the image data and determine () a position of a head () of the patient on a grounds of the at least one reference structure.

X-ray imaging unit for X-ray imaging

Systems and methods for operating an imaging system to perform Cephalometric imaging. The imaging system includes a column, an upper shelf pivotably coupled to the column, a rotating part coupled to the upper shelf and linearly translatable along a length of the upper shelf in a direction radial to the column, a first x-ray source coupled to the rotating part, and an x-ray detector coupled to the rotating part on an opposite side of a first imaging volume from the first x-ray source. A center position of the Cephalometric patient support is determined relative to the imaging system in at least two dimensions by scanning the imaging volume while adjusting a pivot angle of the upper shelf and by scanning the imaging volume while adjusting a linear position of the rotating part along the upper shelf.

Systems and methods for obtaining a panoramic image are provided. One system includes a gantry, an x-ray source, a receptor, and at least one controller. The x-ray source is mounted on the gantry and is configured to alternatively output x-ray radiation at a first energy level and x-ray radiation at a second energy level. The receptor is mounted on the gantry so that x-ray radiation from the x-ray source impinges on the receptor. The receptor is configured to output a plurality of frames of data including a first frame and a second frame sequential to the first frame. The controller is configured to control the x-ray source so that data in the first frame is generated based on x-ray radiation of the first energy level and data in the second frame is based on x-ray radiation of the second energy level.

The application relates to an X-ray imaging unit for a medical imaging. The unit comprising a rotating part comprising a first X-ray source and an X-ray imaging detector unit configured to provide an image by means of at least a rotational movement (R) around a rotation axis of the rotating part, and an upper shelf for supporting the rotating part. The upper shelf is configured to enable the rotating part to move with respect to the upper shelf by means of a linear movement (L) and to be attached to a column with a pivoting joint for enabling a pivot movement (P) of the upper shelf around the column. The rotating part is configured to be positioned by the linear movement and the pivot movement during the imaging.

X-ray imaging systems and methods utilize an imaging apparatus comprising an emitter emitting X-rays through an object and a receiver receiving the X-rays. A control circuit controls the emitter and processes the X-rays received by the receiver to generate X-ray images of the object. The control circuit controls a display to display an initial view of the object, the display of the initial view being modifiable by a user; controls the imaging apparatus to generate an X-ray positioning image of the object based upon a user modification of the display of the initial view; controls the display to display the positioning image, the display of the positioning image being modifiable by a user; and controls the imaging apparatus to generate an X-ray image of the object based upon a user modification of the display of the positioning image.

X-ray imaging systems and methods

The invention relates to a method and system for determining a sharp panoramic image constructed from a group of projection images, especially the invention relates to defining a structure of the panoramic X-ray image of an area of a dentition and of jaws. The structure of a panoramic image to be generated from a group of projection images is determined by at least two crucial parameters, namely parameters of the central surface S of the sharp layer and thickness t(s) of the sharp layer, using penalty function F(S,t), which is at least a penalty function F(S,t) of low-frequency changes in the computed panoramic image corresponding to the choices S and t(S). After computing F(S,t) the best center surface and thickness function (in other words the sharpest layer of the panoramic image) is obtained by minimizing said penalty function F(S,t) over parameter space.
