    Abstract: An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

    Abstract: The present invention relates to acquisition of medical image information of an object. In order to provide a user- friendly alignment of X-ray tube (18) and a detector (24), optionally combined with an anti-scatter grid, an alignment arrangement (200) is proposed, which comprises a tube attachment (26) with a first light projection device (28) and a detector attachment (34) with a second light projection device (36). The first and second light projection devices each generate a light pattern (30, 38) on a projection surface (32). The tube attachment (26) and the detector attachment (34) can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern (38) on the projection surface.

    Abstract: An apparatus (130) and method for automatically or semi-automatically controlling a collimator (COL) of an x-ray imager (100) to collimate imager (100)'s x-ray beam and adjusting an alignment of the x-ray imager (100) in respect of an object (PAT).The collimation and alignment operation is based on 3D image data (3DI) of the object (PAT)to be imaged. The 3D image data (3DI) is acquired by a sensor (S). The sensor (S) operates on non-ionizing radiation. The 3D image data (3DI) describes a shape in 3D of the object (PAT) and anatomic landmarks are derived therefrom to define a collimation window (W) for a region of interest(ROI). Based on the collimation window (W) the collimator (COL)'s setting and imager (100) alignment is adjusted accordingly.

    Abstract: An X-ray imager having a navigation-aid subsystem including one or more transmitters (TX),one or more receivers (RX) and one or more reflectors (RFL). A radio signal is transmitted by transmitter(TX), is then reflected off reflector RFL and is then received at receiver (RX). The received signal is then resolved into positional correction information that can be used to guide a motion of the imager's tube (S) and or detector (D) to position and/or align the tube (S) and/or detector (D) relative to each other in a desired spatial configuration to ensure optimal imaging results. The imager may be a mobile imaging system with the detector (D) portable.
