摘要:
A method and an apparatus are disclosed for checking parameters provided for an examination of a patient with the aid of a contrast medium in a contrast medium injector. The parameters are automatically checked for their medical safety for the patient by taking account of at least one individual datum of the patient with the aid of at least one test criterion, and at least one of a warning signal is output, and/or the operation of the contrast medium injector is stopped when a health risk for the patient is determined.

An imaging device is disclosed for generating successive tomograms of an object. In at least one embodiment, the imaging device includes a radiation source, a detector, a positioning unit and a control unit for controlling the positioning unit and for evaluating the recorded data of the detector. In at least one embodiment, it is provided that the control unit is set up for matching a contrast medium protocol, in which parameters for contrast medium administration are stored, provided for examinations in a contrast medium device, to a scan protocol provided for the examination, in which operating parameters for generating successive tomograms are stored, for preventing unnecessary administration phases. This provides for a contrast medium examination with the least possible contrast medium administration.
摘要:
An operating method for an X-ray machine is disclosed for carrying out a preliminary examination by using a contrast agent, in the case of which a number of heartbeats are determined within a time interval between a first instant of a contrast agent administration and a second instant of a maximum in a concentration of the contrast agent. An operating method for the X-ray machine is also disclosed for carrying out a main examination by using a contrast agent, in the case of which the scanning of the examination region is not started until the number of heartbeats coincides with a preset value such that the scanning is performed at a high concentration of the contrast agent inside the examination region, without the need to adapt the value to the heart rate currently present.

A method and a device are disclosed for identifying and assigning coronary calcification to at least one coronary vessel of a heart in a patient. In at least one embodiment, coronary calcification is identified on the basis of a 3D image data record of the heart in the patient, which data record was generated by an imaging instrument without contrast agent being administered; at least one 3D model of the profile of the coronary vessels in a human is provided; and wherein the identified coronary calcification in the patient is assigned to at least one coronary vessel of the at least one 3D model of the profile of the coronary vessels in a human. At least one embodiment moreover relates to a computer program product, having a computer program that is stored on a medium that can be read by a computational unit, for carrying out the method for identifying and assigning coronary calcification when the computer program is loaded into the computational unit.

An actuation system is disclosed for actuating an ablation instrument for an ablation process in a tissue volume. In at least one embodiment, the actuation system includes: an input interface for image data of the tissue volume; an identification unit for identifying a target tissue using the image data; a model production unit for producing process models and/or refined fine process models of expected ablation developments, which is linked to a value derivation unit for deriving model measured values from a process model and/or to a value determination unit for determining measured values representing the ablation progress; a command derivation unit for deriving control commands on the basis of process models and/or for deriving refined control commands on the basis of fine process models; a comparator for comparing measured values and an instrument interface for transmitting control commands and/or refined control commands to the ablation instrument. In at least one embodiment, the invention also relates to an actuation method.

摘要:
A device and a method are for operating a computer tomograph and an injector, wherein an injector is used to control injection of a contrast medium and a computer tomograph to control a scanning process. Data regarding operation are transmitted between the computer tomograph and the injector via a data interface, especially in a reciprocal manner. The two devices reciprocally influence their operation, thereby reducing the strain imposed on a patient to be examined, increasing operational reliability and simplifying handling.
