1. A method for joint evaluation of a medical image dataset on a first data processing device and at least one second data processing device that is connected to the first data processing device via a data transmission network, the method comprising: performing a first application in the first data processing device and performing a second application in the at least one second data processing device, wherein each of the first application and the second application has a respective graphical user interface having at least one segment for display of a view of the medical image dataset, wherein the view is derived from the medical image dataset by an image processing pipeline that is associated with the respective segment in a multi-stage processing process, wherein the at least one segment of the first application is operated as a presenter segment in that partially processed data of the medical image dataset is decoupled from the image processing pipeline of the presenter segment and is transferred to the second application, and wherein the at least one segment of the second application is operated as an observer segment in that the transferred partially processed data of the medical image dataset is coupled to the image processing pipeline of the observer segment for preparing the view.
