Abstract: A framework for automating clinical scoring for decision support is described herein. In accordance with one aspect, a patient record including corresponding medical image data is retrieved. The medical image data is processed to generate processed medical image data. A set of user interface screens is presented to guide a user through a clinical scoring questionnaire, wherein at least one of the user interface screens displays the processed medical image data. Responses to the clinical scoring questionnaire are received from the user via the set of user interface screens. A clinical score may be generated based at least in part on the responses. A clinical score report based on the clinical score may then be presented.

Abstract: In a method for the administration of medical patient data with a centralized or decentralized patient medical file having secured access enabled by the patient or an enable code administered by the patient, wherein the patient data contain all previous examinations with data representing when the examination was conducted and the findings, a check-in of a patient into the device is implemented before a new examination by the physician, the check-in ensuing upon indication of the initial suspicion as well as of the planned examinations, an enable of these examination via a comparison device, particularly an expert system, ensues only when no relevant, previous examinations are present in a specific, preceding time span, and invoicing for the new examination is possible only in conjunction with a documentation of the examination and its results in the patient medical file.

Abstract: A device is for repeated semi-invasive abrasion of lesions on the walls of hollow organs, in particular blood vessels or the gastrointestinal tract of a patient. The device includes an outer stent which, fixed in position at the site of the lesions, can be clamped against the wall of the hollow organ and has recesses through which the lesions can inwardly protrude. The device further includes a cutting body which is guided within the outer stent and only negligibly narrows the internal bore of the outer stent, which cutting body has cutting edges sliding on the inner side of the outer stent and is coupled magnetically to an external magnet system via which it can turn about the stent axis and/or can move longitudinally along the stent axis.

Abstract: In a method and apparatus to regulate a vessel intervention conducted with a vessel intervention unit, wherein an intervention region of the vessel intervention is at least partially imaged by means of an imaging monitoring unit, and a monitoring region to monitor the vessel intervention is selected, and the vessel intervention is at least partially automatically regulated in the intervention region dependent on at least one characteristic variable identified in the monitoring region.

Abstract: A device is for introducing a stent into a hollow organ, in particular into the gastrointestinal tract of the body of a patient. The device includes a magnet system which covers the area of treatment of the patient and generates a 3D gradient field for remote-controlled movement and orientation of an endorobot. The endorobot is provided with a linear magnet and is freely movable in the hollow organ. Further, the stent, which can be uncoupled from the outside, is secured to the endorobot in a folded-down state so that it can be brought to the site of use and can there be opened out so as to bear firmly on the wall of the hollow organ.

Abstract: A method is for automated localization of lesions in the gastrointestinal tract using laser light from an endorobot. The method includes recording of surface images of the gastrointestinal tract using the camera of the endorobot. Next, the surface images are transmitted to a computer. The surface images are then analyzed by the computer on the basis of lesion-specific features with regard to lesions to be irradiated. Thereafter, control signals are computed by the computer on the basis of a detected lesion, and the control signals are transmitted to an endorobot steering device and/or to a laser system located in the endorobot. Finally, the computed laser-beam orientation and size of the laser irradiation area are adjusted by the endorobot steering device and/or by the laser system, on the basis of the control signals.

Abstract: A device and a method are disclosed for access to at least one information item, which relates to at least one medicament, by a user, in particular in a hospital. At least one mobile electronic appliance is provided for carrying by the user. The appliance includes a reading device which is designed for reading an electronically legible identification which identifies the medicament. The mobile appliance includes a data link to at least one appliance-internal and/or -external memory device in which the information relating to the medicament is stored in such a manner that it is made available to the user via the mobile appliance as a function of the reading of the electronically legible identification of the medicament.

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: In a method for implementation of an imaging measurement procedure, at least three image data sets of at least one region of interest of an examination subject are obtained using different measurement parameters and/or different imaging measurement procedures. A difference image of a first and a second of the image data sets is formed and is superimposed with the third image data set. The superimposition is shown on a display medium.

Abstract: For releasing a therapeutic agent, a release is disclosed. The release allows a release or expulsion of the therapeutic agent that is adapted appropriately for the therapy, and/or for the specific properties of the therapeutic agent.

Abstract: A local coil for magnetic resonance applications has an annular base body in which a reception antenna is embedded to receive a magnetic resonance signal. The base body is fashioned with inherent stability, such that it assumes an inherent form when not subjected to deformation forces. It is dimensioned such that it substantially assumes its inherent form given arrangement in a palate and/or in a nasal cavity of a person. Furthermore, it is flexibly fashioned, such that is can be inserted via a nostril of a person into the nasal cavity and removed again from it.
