Abstract: In a method for generating a presentation for re-locating an information page that was already called proceeding from a home page of an information vendor, and which has been exited in the meantime, the home page being able to be called via the Internet, and an intranet or an extranet, the user is registered when the home page is called. Further, the information pages of the information vendor called by the user directly and indirectly proceeding from the home page are registered; and set up on the home page, and a displayable presentation is generated from which the sequence of the information pages of the information vendor called by the user can be recognized.

Abstract: A method is for verifying the feasibility of a medical study using acceptance criteria for patients. The method includes defining target criteria for the study. Based on the acceptance criteria, a patient collective including potential patients is selected from a database containing patient data of patients. The patient data of the patient collective are evaluated based on the target criteria. Finally, a measure for the feasibility of the study is established.

Abstract: A method for handling an information item (10) which originates from an information provider, is made available by a service provider and can be called via a communications network (5). The service provider allocates to the information provider an ident code (15) which identifies the information item (10). If the information provider does not sign on at the service provider within a specific time period by transmitting the ident code (15), preferably together with a handling instruction (20, 30, 40) relating to the information item (10), the service provider deletes the information item (10).

Abstract: In a method for automated evaluation of a three-dimensional map of a laterally-symmetric organ system as well as medical image acquisition system and a computer program for this purpose, a three-dimensional image of the organ system is segmented, and the segmented organ system is deformed such that the deformed organ system has two mirror-symmetric halves with regard to its external shape. The differences between both mirror-symmetrical halves of the deformed organ system are determined by a comparison of one half with the other half. Alternatively, instead of the deformation of the segmented organ system a mirror-symmetric normal model of the organ system can be deformed, relative to the organ system, or vice versa, such that differences of corresponding regions of both halves of the organ system can be determined using the normal model. The determined differences are presented to a user.

Abstract: A method is disclosed for conducting a clinical study according to which an event occurs during the study that requires a collaboration of individuals responsible for the study. The method includes transmitting the event to a collaboration system. The collaboration system determines, based on parameters assigned to the event, a group of individuals responsible for the study required for the collaboration. The collaboration system provides a communications platform for the group. The group carries out the collaboration while using the communications platform. Finally, the collaboration system verifies the collaboration on the basis of predetermined verification criteria.

Abstract: In a method for determining the effectiveness of a therapy for alleviating a constriction in a blood vessel, the functioning of collateral vessels naturally formed at the constriction is analyzed. The analysis takes place by making a blood flow measurement at the vessel in which the constriction is present, or at a complementary vessel, with the patient experiencing two different stress conditions. The flow measurement can ensue by magnetic resonance or using ultrasound. Comparison of the stress-dependent blood flow to a reference is then undertaken to determine whether the collateral vessels are functioning effectively, and thus whether the treatment for alleviating the constriction is effective.

Abstract: A medical tomography apparatus and method, a 3D dataset is generated in as picture elements arranged in a three-dimensional grid during the examination of a patient. Predefined surfaces are stored in a library and, dependent on the desired examination, one of the predefined surfaces can be selected with an input unit and thus the shape of an evaluation surface can be defined. Picture elements of the 3D dataset along the evaluation surface and used for constructing a two-dimensional image. A pre-defined surface is selected from the library and is employed for determining the shape of the evaluation surface. The method and the apparatus can be particularly employed in a simple way for the multi-planar reconstruction of a two-dimensional image along a multiply or arbitrarily curved surface.

The gradient field and/or the examination subject can be displaced in the spatial direction of the periodicity to generate a relative position change between the periodic gradient field and an examination subject, and the transmission and reception coil system comprises individually-activatable coil arrays to allow data to be acquired to fill in gaps or resolve ambiguous data entries that occur due to the gradient field being periodic.

Abstract: A method is disclosed for determining positron emission measurement information in the context of positron emission tomography. The method includes carrying out a positron emission measurement, in a body area of a subject to be examined, to record positron emission measurement information with point resolution and determining a time frame of the measurement by, at the same time, generating images of the body area to be examined with a relatively higher time resolution and with point-resolved image data, using a second imaging method. Further, a local shift of points of individual images of the second imaging method is determined, caused by movement processes of the subject to be examined, and as a function thereof, of the positron emission measurement information for at least a part of the measurement period and of the body area to be examined. Finally, the positron emission measurement information is adjusted as a function of the determined shift.
