摘要:
There is described a radiography device for recording dynamic processes and an associated recording method. The radiography arrangement is used to examine patients using an x-ray source, a digital flat detector with a single shot recording function and an operating console for controlling and recording purposes, with the flat detector also being able to display an image sequence at a rate of up to 5 Hertz, which allows the positioning of the region to be examined or the monitoring of pseudo-interventional interventions.

A method for sterilizing medical objects in a sterilization device is described. A read facility of the sterilization device first reads a machine-readable information code by means of electromagnetic waves from an identification element associated with the medical object. The number of sterilization cycles already undergone by the medical object in question is determined on the basis of the information code. The number of sterilization cycles already undergone is compared with the maximum number of permitted sterilization cycles the medical object in question is allowed to undergo and a warning signal is automatically triggered and/or the function of the sterilization device is restricted, if the number of sterilization cycles undergone reaches or exceeds the maximum number of permitted sterilization cycles. A corresponding sterilization device and a medical object are also described.
摘要:
A radiotherapeutic device has a radiotherapeutic irradiation unit with a radiation source for generation of radiotherapeutic radiation and a beam guidance and/or beam shaping device in order to direct the radiotherapeutic radiation in a defined manner onto a specific irradiation region. The radiotherapeutic device additionally has an imaging unit that includes a radionuclide emission tomography acquisition unit and a computed tomography scanner. The radiotherapeutic device also has a support device with a positioning device in order to position the support device in an image acquisition position in which a body region to be irradiated of a patient borne on or in the support device is located in an acquisition region of the image acquisition unit, or in order to position the support device in an irradiation position in which the body region to be irradiated of the patient is at least partially located in congruence with the irradiation region of the irradiation unit. The radiotherapeutic device additionally has a coordinate registration device that registers changes of all position coordinates of the support device given a movement of the support device between the image acquisition position and the irradiation position.
摘要:
Diagnosis device for combined and/or combinable radiographic and nuclear medical examinations Digital imaging methods have now become common practice in medical diagnostics. Methods of this type have been used for some time, e.g. in computer tomography, for magnetic resonance examinations, ultrasound examinations and for nuclear medical methods. The object underlying the invention is to propose a diagnosis device for increasing accessibility to a patient. To this end, a diagnosis device (1) is proposed for combined and/or combinable radiographic and nuclear medical examinations with an x-ray source (9), with an examination room for accommodating a patient (5), with a gamma radiation source (6) arranged in the body, with the diagnosis device (1) being designed in order to carry out the radiographic examination by evaluating the measurement of the x-rays, and in order to carry out a single photon emission (SPE) examination as a nuclear medical examination by evaluating the gamma radiation, with a detector system (8a,b, 10) which has a detector surface for simultaneously measuring the x-ray and gamma radiation without changing the patient's position and/or which is designed to record a two-dimensional locally-resolved and object-imaging individual x-ray projection image.

A medical imaging modality with a PET detector ring for Positron Emission Tomography connected on the data side to a PET image processing unit is to be structured in such a way that, on the basis of the images generated in the modality, a reliable detection and precise localization of metabolism anomalies, especially of malign tissue with tumor incidence is possible. The modality is further intended to offer good access to the patient, so that operative or minimally-invasive interventions on the patient can be undertaken and checked alongside the image recording. To this end there is provision, in accordance with the invention, for an ACT recording device for angiographic computer tomography connected on the data side to an ACT image processing unit to be arranged adjacent to the PET detector, whereby a common display unit for display of PET images and/or ACT images generated in the relevant image processing unit is assigned to the PET image processing unit and the ACT image processing unit.
摘要:
The invention relates to a catheter for brachytherapy having a radiation source for generating β or γ rays. In order to be able to position the catheter as accurately as possible it is proposed according to the invention that a position indicating means is provided in the area of a free end of the catheter, by means of which position indicating means a position in a three-dimensional coordinate system can be determined on the basis of interactions produced when an external magnetic field is applied.
摘要:
An endoscopic capsule for wireless transmission of medical images is provided. The capsule comprises a light transmitting unit and a light receiver. If a diseased tissue contains a contrast medium concentrated in the diseased tissue and the diseased tissue is irradiated by excitation light emitted by the light transmitting unit at a specific frequency, fluorescent light detectable by the light receiver occurs at a frequency different from the specific frequency. The light transmitting unit is arranged at a leading end of the capsule and the light receiver is arranged at a trailing end of the capsule.
