A device for determining the regional distribution of a parameter for lung perfusion includes an electrical impedance tomography unit with electrodes (E, . . . EN), which can be placed on the thorax, that are connected to a control and analysis unit () and an administering device () for the intravenous administration of a conductivity contrast medium. The control and analysis unit () is configured to display changes in impedance distribution occurring as a consequence of the administration of conductivity contrast medium as a parameter for lung perfusion in the section plane as a function of time. The administering device () has a controllable dispensing device. The control and analysis unit and the dispensing device are connected with one another via a data link (). A start time and an end time and a quantity of an administered bolus of the conductivity contrast medium are available to the control and analysis unit ().

Device for determining the regional distribution of a parameter for lung perfusion

A device and a method () for the processing of data (), which were obtained by an imaging method, make possible an improvement in a location-specific visualization of the perfusion of the lung. With a reference to a comparison variable, a location-specific variable (), characteristic of a period of observation, regarding the perfusion of the lung and heart region, is determined and provided as an output signal.
