Abstract

A CT system is disclosed for carrying out a monitored intervention with an instrument on a patient. The system includes an arrangement including an X-ray tube for production of a radiation beam which is moved around the patient and a detector with a large number of detector elements for measurement of the radiation intensity after passing through the patient, with the radiation beam scanning a scanning area on the patient. The system further includes an apparatus for variable orientation and positioning of the patient relative to the tube / detector arrangement, and a computation and control unit with computer programs or modules, for controlling the system and for reconstruction of the tomographic records from measurement data in the detector. A first program is stored for running and detects at least a portion of the instrument which is used for intervention, and a second program is stored for running and automatically matches the scanning area to the instrument, in accordance with presets that are provided.

Description

technical field

[0001] The invention relates to a computed tomography system for performing an interventional intervention on a patient with an instrument, having at least one x-ray tube for generating a beam of radiation moving around the patient, and a detector comprising a plurality of detector elements, with After measuring the radiation intensity through a patient, wherein the radiation beam scans a scan area on the patient, the system also has means for variably supporting and positioning the patient relative to the x-ray tube / detector system, and includes a computer A computing and control unit of the program for controlling the system and reconstructing the tomographic image from the measurement data of the detector. Background technique

[0002] In principle, such computed tomography systems are known, which are usually used for invasive interventions on patients under simultaneous control. Such invasive interventions are, for example, extraction of tissue or treat...
