摘要:
In a method, sensor and system for producing time-limited images of a moving organ of a human or animal body, an imaging apparatus acquires image data and, using a sensor situated outside the body, a signal is registered that represents the movement of the organ that is to be imaged. The image data acquisition is coordinated with this signal. A fiber optic sensor is used as the sensor.

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.

A method provides for inputting and storing data for a clinical study in a uniform manner by different study locations. Accordingly, the method comprises generation of an input platform program for an input of data of a clinical study, distribution of the input platform to input locations, calling up and activating the input platform program dependent on a participant characteristic linked with a study participant in the clinical study, inputting the data at an input location via an input platform generated by the input platform program, and storing the input data.

An imaging diagnosis system for generation of a three-dimensional image data set of an examination subject has an image acquisition unit that acquires three-dimensional raw data of the examination subject, an image reconstruction unit that generates a three-dimensional image data set from the three-dimensional raw data, an image processing unit that detects anatomical structures of the examination subject from the image data set, and a position determination unit that determines the position of an anomaly (identified by a diagnostician) in the anatomical structures of the examination subject in the image data set and generates position data for the image acquisition unit. The image acquisition unit acquires perfusion-sensitive raw data with the aid of the position data of the detected anomaly, which perfusion-sensitive raw data contain perfusion information of the identified anomaly.

A computer program product has a check routine and an active part. When the computer program product is called, a computer, while processing the check routine, initiates a transmitter to send a launch signal. A transponder receives this signal, checks whether a time-dependent and/or usage-dependent transmission condition is met and transmits an enable code as warranted. A receiver receives the enable code and communicates it to the computer. The computer checks the enable code and undertakes processing of the active part only when the enable code satisfies an enable condition.

A device is disclosed for calibrating a magnetic resonance apparatus having a PET function. In at least one embodiment, the device includes at least one marker that is visible through magnetic resonance imaging and fixed with reference to the device; at least one holder, fixed with reference to the marker, for a receptacle for holding a PET tracer generating a PET signal during PET imaging; and at least one receptacle for holding a PET tracer.

The invention relates to a sensor device for monitoring accelerations to which an object is subjected. In order to detect whether a value has exceeded or is below a threshold for the acceleration to which objects have been subjected in the past, i.e. without having visual contact with the sensor, the inventive sensor device includes an acceleration sensor, which is permanently linked to the object to be monitored, so that a relative movement between the acceleration sensor and the object is prevented, and an RFID transceiver for non-contact coupling of electrical energy into the acceleration sensor and for sending out radio signals as a function of the physical state of the acceleration sensor.

In a method for testing a software system that operates a technical system including a technical system that is in operation by a customer, an operation model is generated that is based on a reproducible operation procedure under conditions relevant for the customer, and the operation of the technical system is monitored. The software system to be tested on the technical system of the customer is installed, and this technical system is operated and monitored with the operation model. Subsequently the operation of the technical system of the customer is evaluated with the operation model with regard to possible faulty executions.

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.
