摘要:
An image-monitoring method for an electroporation treatment with an electroporation appliance is provided. The electroporation appliance comprises at least two treatment electrodes and an image-monitoring appliance. At least one image monitoring measurement is performed by the image-monitoring appliance after the administration of a contrast agent and after the electroporation treatment.
摘要:
In a magnetic resonance marking system marking a flowing medium in a marking region, as well as in a magnetic resonance system with such a magnetic resonance marking system, a method to control a magnetic resonance marking system, and a method to generate magnetic resonance exposures, a radio-frequency transmission device generates marking radio-frequency signals, and a marking radio-frequency transmission coil emits the marking radio-frequency signals in the marking region. A magnetic field determination device determines a magnetic field strength in the marking region, and a control unit derives a marking transmission frequency from the determined magnetic field strength and to control the radio-frequency transmission device so that marking radio-frequency signals at the derived marking transmission frequency are emitted by the marking radio-frequency transmission coil.

A thermal ablation device for introduction of heat or cold into the body of a patient has a first heating or cooling device to heat or cool the tissue to be ablated, as well as at least one additional cooling or heating arrangement that serves to cool or heat tissue surrounding the tissue to be ablated, and that can be introduced into a natural or latent cavity of the patient.
摘要:
The invention relates to a method for displaying image data of a part of a patient's body, in which the part of the patient's body comprising regions which are provided with a radiation-emitting contrast agent is detected in a first step by means of a detection device, wherein during the first step, the intensity of the radiation emitted by the regions provided with the contrast agent is higher than the intensity of other radiation which can be detected by the detection device and which is emitted by the detected part of the patient's body, wherein a patient image data set is produced on the basis of the detected radiation, and wherein the patient image data set is displayed to a user by means of an output device in a second step. The invention also relates to a device for displaying image data of a part of a patient's body, comprising: a detection device which comprises at least one camera for detecting radiation emitted by regions of the part of the patient's body which are provided with a radiation-emitting contrast agent; a computational unit which produces a patient image data set on the basis of the images detected by the detection device; and an output device for displaying the patient image data set produced.
