[0005] Furthermore, X-ray fluoroscopic images may suffer from poor contrast such that the patient's anatomy may be difficult to view in such fluoroscopic images and it may be difficult to determine where an interventional device is positioned relative to the patient's anatomy

Embodiment Construction

[0041] figure 1 An x-ray medical imaging system 10 is schematically shown that may be used during an interventional procedure to provide an image representation, thereby supporting a surgeon in positioning an interventional device within a patient in accordance with an embodiment of the present invention.

[0042] The imaging system 10 comprises an X-ray image acquisition device having an X-ray source 12 provided to generate X-ray radiation. The X-ray source 12 includes a collimator 13 including shutters and wedges (not shown) in order to collimate the X-radiation onto the region of interest. A patient table 14 is provided for receiving a patient to be examined. Furthermore, the X-ray image detection module 16 is positioned relative to the X-ray source 12 . During an imaging procedure, a patient is positioned on a patient table 14 , ie between an X-ray source 12 and a detection module 16 . X-rays are emitted by an X-ray source 12 and transmitted through the patient before b...

Abstract

A medical imaging device and a method for providing an image representation supporting positioning of an intervention device such as a wire tip (4) in a region of interest during an intervention is proposed. Therein, the following process steps are to be performed: (S1) acquiring a pre-live anatomy image (1) including a region of interest; (S2) acquiring a live anatomy image using a live image acquisition device comprising an adjustable collimator device; (S3) identifying a location (5) of the intervention device (4) within the live anatomy image; (S4) adjusting settings of the collimator device based on the identified location of the intervention device for subsequently acquiring a further live anatomy image representing the region of interest using the live image acquisition device with the collimator device being in the adjusted settings; and providing (S5) the image representation by merging information from the live anatomy image into the pre-live anatomy image.. Thereby, the intervention device may be continuously tracked and the collimator device may restrict a field of view to a location of the intervention device thereby significantly reducing an applied X-ray dose. Background anatomical information may be introduced into the final image representation using the pre-live anatomy image possibly having a higher image contrast than the live anatomy images.

Description

technical field [0001] The present invention relates to a medical imaging device for providing an image representation that supports positioning of an interventional device in a region of interest during a medical interventional procedure. Furthermore, the present invention relates to a medical imaging system, a medical imaging method, a computer program and a computer readable medium, all of which are adapted to provide images for supporting e.g. a surgeon during the positioning of a medical interventional device express. Background technique [0002] During a medical interventional procedure, it may be necessary to accurately position one or more interventional devices within a region of interest within a patient. For example, during cardiac catheterization, it may be necessary to position a guidewire tip at a precise location within the vascular system. To assist the physician in such positioning, medical imaging devices are typically provided to display image represent...
