Abstract
With a method for generating an x-ray image sequence for supporting an intervention on a patient with a catheter or guide wire for instance, automatic recognition of the catheter is carried out with recorded x-ray images using a computer system. The x-ray image recording parameters are changed on the basis of the determined quality of the imaging of the object, with the x-ray device preferably being automatically activated with the changed x-ray image recording parameters, to record x-ray images. The doctor can therefore concentrate on the actual intervention and does not have to worry about operating the x-ray device.
Claims11
A method for generating a medical x-ray image sequence with a medical x-ray device, comprising:
- adjusting a first x-ray image recording parameter of the x-ray device;
- recording an x-ray image of an object to be imaged using the adjusted x-ray device, the object to be imaged is an interventional instrument;
- subjecting the recorded x-ray image to a computer system for an automatic computer object recognition and a determination of a variable relating to a quality of an imaging of the object to be imaged, wherein the computer system determines whether a structure in an area around the object in the x-ray image is imaged;
- determining an adjustment of the first or a second x-ray image recording parameter by the computer system based on the variable;
- changing a setting of the x-ray device based on the adjustment, wherein an x-ray device with an x-ray C-arm is used and an angulation of the x-ray C-arm over an axis and a distance of an x-ray detector from an x-ray emitter are adjusted as a function of a computer-detected area around the object;
- and
- further recording a further x-ray image using the changed setting x-ray device.
A method for generating a medical x-ray image sequence with a medical x-ray device, comprising:
- adjusting a first x-ray image recording parameter of the x-ray device;
- recording an x-ray image of an object to be imaged using the adjusted x-ray device;
- subjecting the recorded x-ray image to a computer system for an automatic computer object recognition and a determination of a variable relating to a quality of an imaging of the object to be imaged, and wherein the computer system determines whether a structure in an area around the object in the x-ray image is imaged;
- automatically determining an adjustment of the first or a second x-ray image recording parameter based on the variable and automatically changing a setting of the x-ray device based on the adjustment, and wherein the method uses an x-ray device with an x-ray C-arm and an angulation of the x-ray C-arm over an axis and a distance of an x-ray detector from an x-ray emitter are adjusted as a function of a computer-detected area around the object;
- and
- further recording a further x-ray image using the changed setting x-ray device.
A medical x-ray image recording system, comprising:
- an x-ray device;
- and
- a computer system that:
- automatically recognizes an object in an image recorded by the x-ray device, and whether a structure in an area around the object is imaged, wherein the object to be imaged is a catheter in an intervention procedure,
- determines a variable relating to a quality of an imaging of the object in the image, and
- automatically activates the x-ray device as a function of the variable.
