摘要:
In a method for implementation of an imaging measurement procedure, at least three image data sets of at least one region of interest of an examination subject are obtained using different measurement parameters and/or different imaging measurement procedures. A difference image of a first and a second of the image data sets is formed and is superimposed with the third image data set. The superimposition is shown on a display medium.
摘要:
In a method and apparatus to regulate a vessel intervention conducted with a vessel intervention unit, wherein an intervention region of the vessel intervention is at least partially imaged by means of an imaging monitoring unit, and a monitoring region to monitor the vessel intervention is selected, and the vessel intervention is at least partially automatically regulated in the intervention region dependent on at least one characteristic variable identified in the monitoring region.

A local coil for magnetic resonance applications has an annular base body in which a reception antenna is embedded to receive a magnetic resonance signal. The base body is fashioned with inherent stability, such that it assumes an inherent form when not subjected to deformation forces. It is dimensioned such that it substantially assumes its inherent form given arrangement in a palate and/or in a nasal cavity of a person. Furthermore, it is flexibly fashioned, such that is can be inserted via a nostril of a person into the nasal cavity and removed again from it.

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.
摘要:
In a method for the administration of medical patient data with a centralized or decentralized patient medical file having secured access enabled by the patient or an enable code administered by the patient, wherein the patient data contain all previous examinations with data representing when the examination was conducted and the findings, a check-in of a patient into the device is implemented before a new examination by the physician, the check-in ensuing upon indication of the initial suspicion as well as of the planned examinations, an enable of these examination via a comparison device, particularly an expert system, ensues only when no relevant, previous examinations are present in a specific, preceding time span, and invoicing for the new examination is possible only in conjunction with a documentation of the examination and its results in the patient medical file.
摘要:
A device is for repeated semi-invasive abrasion of lesions on the walls of hollow organs, in particular blood vessels or the gastrointestinal tract of a patient. The device includes an outer stent which, fixed in position at the site of the lesions, can be clamped against the wall of the hollow organ and has recesses through which the lesions can inwardly protrude. The device further includes a cutting body which is guided within the outer stent and only negligibly narrows the internal bore of the outer stent, which cutting body has cutting edges sliding on the inner side of the outer stent and is coupled magnetically to an external magnet system via which it can turn about the stent axis and/or can move longitudinally along the stent axis.

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:
Magnetic recording tape especially suitable for use as video tape and computer tape, comprising a base carrying a magnetic coating which consists essentially of a dispersion of a finely divided magnetic pigment and at least one lubricant in an organic binder. The lubricant is a compound of the formula ##STR1## IN WHICH N IS AN INTEGER OF FROM 3 TO 8 AND R.sup.1 and R.sup.2 are an alkoxy or aralkoxy radical or conjointly are an alkyldioxy radical of 3 to 18 carbon atoms. A magnetic recording tape prepared with a high proportion of such a lubricant is distinguished by high abrasion resistance coupled with a minimum transfer of material to the magnetic heads even under fluctuating climatic conditions.
