In order to optimize the recording time, provision is made of a method for recording an X-ray image using an X-ray system with an X-ray detector, an X-ray source, a system control, and a computational unit, wherein information relating to the relative direct radiation component in a reference X-ray image and information relating to the utilized recording geometry and/or the utilized primary X-ray dose and/or the utilized filtering is used to determine a relaxation time, during which a ghosting effect of the X-ray detector resulting from a preceding X-ray image decays at least in part, which relaxation time is adapted to the X-ray image to be recorded, and the determined relaxation time is utilized to actuate the recording of the X-ray image.

The invention relates to a medical system comprising a detection device for detecting an object in at least two dimensions by x-rays. The detection device is constructed to detect the object and to produce data comprising a 2D data record or a sequence of 2D data records over time representing the object in a projection through the object in two dimensions and to output the data. The medical system comprises at least one storage device with a data input actively connected to the detection device and which is constructed to receive the data at the input side and to write on a storage medium, in particular a portable storage medium, in such a way that the storage medium represents the data so it can be read out again. The medical system is constructed to digitally transmit the data from the detection device through to the storage device.

In a method for implementation of a medical procedure on a patient with a first medical apparatus that processes patient data and a second medical apparatus that processes patient data, both apparatuses have interfaces that can be connected with one another for exchange of the patent data. Patient data of the patient is electronically stored in the first apparatus, the interfaces of both apparatuses are connected, the patient data is transferred from the first apparatus to the second apparatus, and the procedure is implemented with the second apparatus.

An installation for image-assisted shockwave therapy has a C-arm x-ray unit that is orbitally movable around an isocenter, and that carries an x-ray imaging system thereon. The installation also has a shockwave head and a carrier device for the shockwave head that is disposed stationarily relative to the x-ray C-arm. A boom that extends toward the x-ray C-arm is carried by the carrier device, the boom having a free end at which the shockwave head is mounted. The boom is movably guided by the carrier device so that the shockwave head is arbitrarily movable to any position and can be arbitrarily aligned to the isocenter within a minimum range of 180&#xb0; delimited by the top table position and the bottom table position of a patient table.

A non-invasive medical treatment installation has a therapy C-arm mounted on a base, and defining an isocenter. A therapy apparatus having a focus is mounted at the free end of a carrier arm, that has a fixed end attached to the therapy C-arm. The mounting of the fixed end of the carrier arm to the therapy C-arm allows orbital movement of the carrier arm along the therapy C-arm between two final positions respectively delimited by the opposite ends of the C-arm. The carrier arm is mounted to the therapy C-arm to allow rotation of the carrier arm around a rotational axis, so that when the carrier arm is at either of said final positions, it extends beyond the respective end of the C-arm.

In a method and x-ray apparatus for exposure of a patient who can be placed at a variable distance relative to an x-ray source, the dose rate emitted by the x-ray source is reduced given reduction of the distance and/or increased given increase of the distance.

In a method and an apparatus for filtering a digital image acquired with a medical device by means of a spatial-frequency operator that automatically allow an optimum filtering of the source image, the integral signal-to-noise ratio of the digital image is calculated, a limit value for the integral signal-to-noise ratio of the filtered image is calculated from the integral signal-to-noise ratio of the digital image, the digital image is iteratively filtered with the spatial-frequency operatorwith variation of the dosage g and with calculation of the integral signal-to-noise ratio in the filtered image, afterward iteration of the integral signal-to-noise ratio of the filtered image is compared to the limit value for the integral signal-to-noise ratio, the iterative filtering of the digital image with the spatial-frequency operatoris aborted when the integral signal-to-noise ratio of the filtered image reaches the limit value for the integral signal-to-noise ratio or when a range of control (if present) for the dosage g has been exhausted, and the dosage g most recently employed in the iterative filtering is employed as the optimum dosage gfor a filtering of the entire digital image under consideration with the spatial-frequency operatoremployed.
