Abstract: According to an exemplary embodiment of the invention a dose awareness indication device is provided in which an individual dose is determined on the basis of raw dose measuring data, dose sensor and information data from an examination apparatus, wherein the information data from the examination apparatus relates to the type of examination. Thus, an individualized determination of dose data may be provided, depending on the actual examination process.

Abstract: The field of the invention is diagnostic and interventional radiology and the invention is a dose indicator for use in a system for performing radiological procedures using ionizing radiation, for indicating a dose of radiation received in an area of skin by a subject during the radiological procedure, in which a zone is displayed which is representative of the extent of the area of skin exposed, and in which is a value of dose is displayed which is associated with the zone. The value of dose is representative of the dose of radiation received in the area of skin exposed during the procedure. The display is easily and quickly understood allowing the user of the system to swiftly understand the skin dose accrued by the patient. The use of zones provides an intuitive display.

Abstract: Absorption filters are positioned in an x-ray examination apparatus according to the invention by adjusting them on the basis of the posture of the carrier supporting the x-ray source and the x-ray detector. To that end adjustment curves relating carder posture to filter adjustment are employed. The posture of the carder determines the orientation of the x-ray beam path. Because there are relatively few anatomical differences among patients to be examined, the adjustment of absorption filters on the basis of the beam orientation is quite adequate. Further improvement is achieved by providing sets of adjustment curves, each set pertaining to a class of patients, such as e.g. corpulent or slender patients, or infants or adults.

Abstract: X-ray examination apparatus comprising adjustment-control means and adjustment-control means for use in an X-ray examination apparatus.An X-ray examination apparatus is provided with adjustment-control means suitable for retrieving the orientation of the X-ray beam and of the X-ray beam optics as were employed for making a reference image. Thus the X-ray examination apparatus can be automatically and accurately placed in the same imaging conditions in which a previous image was made.
