However, in other medical applications, such as in cardiac interventions, this method cannot be used, because in that case the X-ray image would not include any direct radiation area anyway

[0030] specific implementation plan

[0031] In order to generate an X-ray image of the body of the patient 5, the X-ray unit comprises an X-ray radiation source 7 and an X-ray detector 4, wherein the X-ray radiation source 7 has a device for generating X-rays with the help of an X-ray voltage supplied by a generator The X-ray tube that emits radiation, and the X-ray detector 4 measures the X-ray radiation that passes through the body of the patient 5 with position resolution. The X-ray detector 4 is also coupled to the image acquisition unit 1, which is used to read data from each image sensor. The control of the X-ray unit and the processing of the acquired (digitized) X-ray images are carried out by the data processing unit 2 , which is thus coupled to the image acquisition unit 1 and the X-ray radiation source 7 . In addition, the data processing unit 2 is also coupled to a system console 8 and a display unit 3 for displaying acquired X-ray images, through which a user can ...

Abstract

The invention relates to a method and a unit for automatically adjusting a collimator ( 6 ). In this connection, a region ( 9 ) of interest inside the body is determined in an application-specific way from an analysis of first X-ray pictures, and the collimator ( 6 ) is then adjusted thereon. The region ( 9 ) of interest can, in particular, be chosen to be large enough for the irradiation field to cover all those positions of an organ ( 10 ) of interest that occur as a result of heartbeat and / or respiration. Preferably, a movement estimate' is undertaken during a current examination in order to be able to readjust the collimator ( 6 ) if necessary. If the region of interest cannot be localized, the collimator ( 6 ) is opened to a standard adjustment.

Description

technical field [0001] The invention relates to an x-ray unit for generating body images, which unit has an automatically adjustable collimator. Furthermore, the invention relates to a method for generating an X-ray image of a body using automatic adjustment of a collimator. Background technique [0002] X-ray units for recording medical X-ray images generally comprise a collimator with an opaque closed part and a semi-transparent diaphragm wedge, the adjustment of which enables the shaping of the X-ray beam in such a way that That is, only the part of interest of the patient's body is irradiated with the desired radiation intensity. In addition, collimators often include filter elements in order to change the spectrum of the light beam in a desired manner. The most important advantages of using a collimator are that it improves image quality, reduces the risk of radiation damage (eg, skin damage) to the patient, and reduces worker exposure to scattered radiation during im...
