摘要:
A method for safety-directed wireless signal transmission is provided. The method includes duplicating an input signal; supplying each copy of the duplicated input signal within a source unit to a transmitter module over separate, independent software paths; transmitting the copies using the transmitter module over a common wireless transmission link to a receiver module of a sink unit; supplying each transmitted copy within the sink unit over an independent software path to a comparator module; and using the comparator module to test the output copies for consistency with an output signal corresponding to the output copies being generated by the comparator module.

A radio operating system, in particular for a medical device, comprises: a radio base station, provided for control of a device, an operating unit, for establishment of a radio connection with the radio base station, whereby the operating unit comprises a controller with a first threshold value (S1) relating to a reception parameter (K), depending on which a switching between various operational modes (B0, B1) for the operating unit is provided. On dropping below the threshold value (S1), a safety-oriented operating mode (B0) and, on exceeding the threshold value (S1), a standard operating mode for the operating element (3), are provided. A first non-safety-critical command set (BS1) may be activated by the operating unit and equally used in the various operating modes (B0, B1), a second safety-critical command set (BS2), activated by means of the operating unit, may be used in the safety-oriented operating mode (B0) in a limited manner in comparison to the standard operating mode (B1).

摘要:
An apparatus for medical diagnosis and therapy systems has at least one operator control device generating at least one control signal corresponding to at least one function of the apparatus, a control unit for converting the at least one control signal into the at least one function of the medical apparatus, a signal transmission device for wireless transmission of the at least one control signal from the at least one operator control device to the control unit of the medical apparatus, and at least one console adapted for detachably engaging the at least one control device. The signal transmission device has at least one first transmission unit in communication with the at least one operator control device and at least one second transmission unit in communication with the control unit. At least one interference-free transmission path is established when the at least one control device is engaged with the at least one console.
摘要:
A safety apparatus for a medical system comprises at least one source for emitting an optical signal, and at least one sensor for detecting the optical signal emitted by the at least one source. The at least one source and the at least one sensor are disposed such that an object located in a region to be monitored is detected. A control unit is provided for controlling the medical system, so that the medical system is switched into a safe operating state or interrupted if the detected object is unexpected or unwanted in the monitored region.

摘要:
In a method and a device for positioning a patient in a medical diagnosis device or therapy device, an image-recording device records an image of the patient, which is displayed on a screen, and an image processor aids the positioning of the patient. At least one body region is automatically detected by the image processor, and a scan area is automatically suggested on the screen that covers the body region.
摘要:
The invention relates to a method for repositioning a patient in a diagnostic/therapeutic system, as well as to such a system, wherein a repeated, accurate repositioning is achieved by producing difference images from a reference image and a current image, each in two recording axes, which are independent of each other, and by subsequently minimizing the visible differences. The reference images are produced with the same camera setting as the current images.
摘要:
In a method and a device for positioning a patient in a medical diagnosis device or therapy device having a position calculating device and a patient bed adjustable in at least one plane, at least one optical target marking is brought into conformity with a body region of the patient. At least one image recording device is used for obtaining an exterior image of the patient that is displayed on a screen. The target marking that is spatially coupled with the coordinate system of the diagnosis device or therapy device, is superimposed on the image of the patient on the screen such that a predetermined body region of the patient can be brought into a desired spatial correlation with the target marking by remote control movement of the patient bed.
