A method is proposed for determining clinical study compliance. The method includes obtaining criteria for the clinical study and accessing stored clinical data relating to the clinical study. Thereafter, the criteria and clinical data are correlated to determine a measure of compliance with the criteria of the clinical study.
摘要:
An endocapsule has a measurement chamber therein containing a sensor that detects at least one metabolic product of a specific bacterium in a hollow organ of a human or animal gastrointestinal tract. The endocapsule is introduced into the hollow organ wherein detection of the at least one metabolic product takes place.

In a method and a device to detect information about the three-dimensional structure of the inner surface of a body cavity (2) of a patient with an endoscopy capsule (4) introduced into said body cavity (2), a first partial region of the inner surface of the body cavity (2) is illuminated with at least one light source (16) arranged in the endoscopy capsule (4): and an image of a second partial region (36) that is illuminated by the first partial region (30) and differs from said first partial region (30), the three-dimensional structure of which second partial region (36) is known, is acquired with at least one camera (18) arranged in the endoscopy capsule (4). Information about the three-dimensional structure of the first partial region (30) is derived using the intensity values present in this image.
摘要:
A system for detection, administration and/or evaluation of configuration data describing the hardware or software configuration of different (in particular medical technology) devices has a central database (in particular manufacturer-spanning central database) the configuration data stored therein, which is connected to a network (in particular the Internet via at least one software unit (fashioned as a programming interface and/or Internet platform), which enables a role-specific access to the database via role-based interfaces. An operator role and/or an end user role (in particular a referrer and/or patient role) and/or a manufacturer role are provided as roles.
摘要:
A gastroscope has an insertion tube with a distal end, at which a sensor is located. The sensor has a first electrode produced of an acid-resistant noble metal, and a second electrode produced of silver. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable is measured between the first and second electrodes, when ammonia is present. The gastroscope allows screening of gastric acid and the tissue of the stomach lining for Helicobacter pylori in a manner that is gentle for the patient.
摘要:
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.
摘要:
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.
摘要:
The invention relates to an upper body MRI scanner comprising a magnet arrangement for producing a horizontally oriented homogeneous main magnetic field, said magnet arrangement being designed to examine the upper body of a standing patient. An image acquisition unit is provided for continuously creating upper body images of the standing patient. A quality checking unit is designed for automatically determining a quality metric characterizing the quality of the upper body images. An imaging controller connected to the image acquisition unit and the quality checking unit is provided for activating the image acquisition unit and outputting signals for influencing the position and/or behavior of the patient as a function of the characteristic quality metric. An output unit connected to the image acquisition unit is used for displaying and/or storing at least some of the upper body images.
摘要:
In a method and system for automatically processing studies of imaging examination systems, each of the studies is given a priority code. Dependent on its priority code, the study is either processed immediately on a first computer allocated to the appertaining imaging examination system or the study is first intermediately stored in a memory device for a later processing, and an identifier allocated to the study is stored in a processing job list. At later points in time, the studies whose identifiers are stored in the processing job list are processed according to a predefined sequence. The first computer has further computers allocated to it for this purpose. The availability of the allocated, further computers is then checked and, insofar as one of the allocated computers is available for a processing of the study, an intermediately stored study is communicated to the appertaining, allocated computer for processing.
