METHODS AND SYSTEMS FOR CALIBRATING AN X-RAY APPARATUS

The present disclosure relates to methods and systems for calibrating an X-ray apparatus. The X-ray apparatus may include an X-ray detector and a collimator. To calibrate the X-ray apparatus, the methods and systems may include moving the X-ray detector from a first position to a second position along a first axis of a coordinate system, wherein the first position is under a scanning table, and the second position is outside the scanning table; moving the collimator to align the collimator with the X-ray detector at the second position; determining one or more parameters; and determining a second value of the first encoder when the collimator is aligned with the X-ray detector at the first position based on the one or more parameters.

RECOGNIZER OF STAFF OR PATIENT BODY PARTS USING MARKERS TO PREVENT OR REDUCE UNWANTED IRRADIATION

An imaging system (10) and related method, where a marker detection system (MDS) detects one or more markers (MK) spatially arranged in association with an area (A). If the marker detection system (MDS) detects that the area (A) is within a field-of-view (FoV) of the imaging system (10) or is at least within a predefined distance thereof, a control signal is issued in respect of said area (A) to an image acquisition system (ACS) of the imaging system (10). The area (A) may be one of a hand (32) of a human operator or a part of a patient (12) to be imaged.

This invention relates to an apparatus made of a grid having a plurality of dimensioned radio-opaque lines relating to surgical variables and a sealable container sized to receive the dimensioned grid.

Patient positioning in diagnostic imaging

A positioning system (10) for positioning a patient (101) for diagnostic imaging is provided. The system comprises a sensor arrangement (12) with at least one sensor (14, 16) configured to provide a sensor signal indicative of at least one body parameter of the patient (101), a controller (18) configured to determine a value of the at least one body parameter based on the sensor signal of the at least one sensor (14, 16), and at least one actuatable support (20) configured to move at least one of an arm (105) and a leg (107) of the patient with respect to a torso of the patient. Therein, the controller (18) is configured to actuate the at least one actuatable support (20) depending on the determined value of the at least one body parameter to move at least one of the arm and the leg relative to the torso of the patient, such that the patient is guided to a posture for diagnostic imaging.

STATIONARY INTRAORAL TOMOSYNTHESIS IMAGING SYSTEMS, METHODS, AND COMPUTER READABLE MEDIA FOR THREE DIMENSIONAL DENTAL IMAGING

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.

Provided is a medical image imaging apparatus that images a medical image of a breast, including a determination unit configured to determine an insertion state of the breast based on a form of the breast inserted into an imaging area for the medical image from an insertion portion.

Determining a value of a recording parameter by use of an anatomic landmark

A method and an imaging system are disclosed. The method, for determining at least one value of at least one recording parameter for a recording of an X-ray image of a patient positioned on an examination table, uses contactless scanning of at least part of the surface of the patient via at least one electromagnetic sensor, to calculate the three-dimensional contour of the scanned surface without additional exposure to radiation. At least one anatomic landmark of the patient can be identified using the three-dimensional contour, and the position of the anatomic landmark is determinable in the coordinate system of the table. The value of the recording parameter is determinable using the position of the anatomic landmark. The value of the recording parameter is determinable quickly and easily since contactless scanning of surfaces can be achieved quickly and easily in terms of technology.
