Medical examination or treatment device, in particular x-ray or CT device, comprising a control device controlling the operation of one or a number of device elements, as well as at least one mobile control element assigned to the control device, the control element communicating wirelessly with the control device for operating the examination or treatment device to issue control signals, with a detector element for detecting an item of information which can be read out or sent by a control element assigned to the control device during a movement of the control element from the room containing the medical examination or treatment device, the room communicating with the control device which disables the control operation as a function of the detection result.

Medical examination or treatment device, in particular x-ray or CT device

The invention relates to a medical diagnostic device comprising an operating element for controlling system components of the medical diagnostic device, said device comprising at least one operating lever which is embodied in such a way that it has at least one feature which is characteristic of the associated system component and is, for example, designed in such a way that it is congruent to the system component. In this way, the operating lever has a form adapted to that of the real system components or has the same form as said components.

To facilitate an intuitive operation of an adjustable device of a medical apparatus, a system for the automatic setting of an operating configuration of the portable control module controlling the adjustable device is provided. Different operating configurations regarding the directional control of the movement of the movable device differ are based on the relative spatial position of the adjustable device with respect to the control module. The system includes at least one signal sender unit for sending a signal. The signal sender unit may be arranged on the control module. The system further includes at least two signal converter units for converting and retransmitting or for converting and reflecting the signal. The signal converter units may be arranged on different positions on the device. A signal receiver unit is used for receiving the converted signal, and the receiver unit may be arranged on the control module.

Medical apparatus and method

Robotic positioning device for a medical imaging unit

To avoid manual adjustments, the invention relates to a method for displacing a superimposed measuring surface on a sensor surface of an x-ray detector in an x-ray system, with an x-ray source and the x-ray detector forming a recording system and being at a fixed distance from one another, with the recording system being moveable in a three-dimensional manner relative to an object to be examined, comprising: the superimposed measuring surface is displaced on the sensor surface of the x-ray detector by a first distance in a first direction; and the recording system is moved by a second distance in parallel with the first distance in a second direction, which is opposite to the first direction, whereby after implementing one of the two steps, the other step is respectively automatically implemented such that a previously superimposed examination area of the object remains superimposed on the displaced measuring surface.

Medical examination or treatment apparatus, in particular X-ray or CT apparatus, comprising a controlling system controlling the operation of one or more apparatus elements, and at least one mobile operating element which is assigned to the control-ling system and which communicates wirelessly with the control-ling system for operating the examination or treatment apparatus for the transmission of operating signals, there being pro-vided at least one device which operates in a direction-selective and/or frequency-selective manner to modify the operating signals transmitted by the operating element such that a controlling system of examination or treatment apparatus disposed adjacent the examination or treatment apparatus to be intentionally operated is not activated by the modified operating signals or there being provided on the examination or treatment apparatus assigned to the operating element at least one acoustic and/or visual signal transmitter which is actuated when an operating signal is generated by the assigned operating element.

Medical examination or treatment apparatus

In a computed tomography apparatus, and a method for operating same, for obtaining cardiac images, a spiral scan of a measurement volume containing a patient's heart is conducted, the production of the scanning data during the spiral scanning being synchronized with an ECG signal from the patient, in order to produce a graphic representation of the examination volume, and thus an image of the patient's heart. The ECG signal is employed to control the generation of the data during the spiral scanning at phase of the cardiac cycle wherein minimum movement of the heart takes place. The chronological correlation between the recording of the scanning data and the ECG signal is fixed, so that within each number of successive time intervals, a dataset is obtained completely within that time interval. The datasets from the successive time intervals are then combined to produce an image of the heart. Since the component images are all obtained in a low-motion phase of the heart, the resulting overall image is particularly sharp.

Spiral scanning computed tomography apparatus, and method for operating same, for cardiac imaging

A computed tomography apparatus is equipped with a device for marking a guide path on a patient for a medical instrument to be used in a medical procedure, such as a puncturing needle. The computed tomography apparatus produces a planning image, and a guide path is identified within the planning image. A computer, using the planning image and the path identified thereon, automatically adjusts a position of a light source, and if necessary a patient table on which a patient is supported, so that a beam from the light source is positioned to coincide with the guide path identified on the image.

Device for making a guide path for an instrument on a patient

A method and apparatus for identifying the distribution of the dielectric constants in an object employ radiation emitted by a microwave transmitter directed at the object, which radiation is received by a microwave detector array. The dielectric constant distribution is calculated in a computer from the output signal of the detector array, and is represented on a monitor. The transmitted and scattered radiation is acquired by the array in a prescribed volume in terms of amplitude and phase. For this purpose, the array has a surface with detector elements thereon which is linearly displaceable in a direction toward the microwave transmitter in steps along a selected path. At each step, the incoming radiation is identified in terms of amplitude and phase at a plurality of measuring locations, the number of measuring locations corresponding to the number of individual detector elements within the array. This measuring phase is thereafter combined with a calibration phase for further processing.
