Abstract: A method for generating and adjusting an image obtained based on computed tomography data using a non-linear blending function is provided. In one embodiment of the method, first image data is obtained using a first X-ray energy, and second image data is obtained using a second X-ray image energy. An image is generated by blending the first and second image data using the non-linear function. The first X-ray energy and the second X-ray energy are different.

Abstract: A method is provided to select a value of a voltage to be set at an x-ray tube of a computer tomography for scanning a patient before an acquisition of x-ray projections of a body region of the patient so as to reduce the dose of x-ray radiation to be applied to the patient in the course of the scan. According to the method, the selection of the value of the voltage takes place under consideration of at least one item of information that can be learned from a topogram of the patient and at least one item of information about the patient that can be learned from a patient file of the patient. The invention also encompasses a computer tomography apparatus with a computer for the execution of the method, as well as a data medium on which is stored a computer program that can be executed on a computer device to perform the method.

Abstract: A system automatically adaptively determines contrast agent administration parameters for use in a CT scan imaging system. The system includes a repository, input processor, imaging processor and output processor. The repository includes predetermined information associating, a contrast agent type, contrast agent administration parameters, an imaging system X-ray tube voltage and at least one of, (a) a type of imaging procedure and (b) an anatomical region to be imaged. The input processor receives data identifying a type of imaging procedure or an anatomical region to be imaged. The imaging processor uses the information in automatically identifying contrast agent parameters and X-ray tube voltage in response to the received data. The output processor provides output data to a destination device indicating contrast agent parameters for use in administering contrast agent to a patient.

Abstract: Example embodiments of the present invention relate to a method for determining the temperature distribution in a tissue to be ablated and/or in a body tissue of a patient containing the tissue to be ablated. The method includes determining at least one item of information relating to a blood flow associated with at least one of in the tissue to be ablated and in the body tissue containing the tissue to be ablated, such that the item of information originates from a perfusion measurement of at least one of the tissue to be ablated and the body tissue containing the tissue to be ablated. The method includes determining the temperature distribution in the tissue to be ablated and/or in the body tissue containing the tissue to be ablated taking into account the at least one item of information relating to the blood flow.
