Abstract
The disclosure generally relates to dual-energy imaging, and in particular, techniques to produce and process dual-energy images using a dual-energy imaging system. One embodiment provides a method for generating at least one image of a region of interest in a patient, the method comprising: obtaining at least two radiological images of the region of interest identified with at least one marker arranged on and/or around the patient, wherein a first image is acquired with a first X-ray energy and a second image is acquired with a second X-ray energy; and determining a final radiological image of the region of interest by linearly combining the two radiological images to obtain an image without the markers.
Claims15
A method for generating at least one image of a region of interest in a patient, the method comprising:
- obtaining at least two radiological images of the region of interest with a medical imaging system, wherein the at least two radiological images of the region of interest are identified with at least one marker arranged on and/or around the patient, wherein a first image was acquired with a first X-ray energy and a second image was acquired with a second X-ray energy;
- and
- determining with a processing system of the medical imaging system a final radiological image of the region of interest by linearly combining the at least two radiological images of the region of interest obtained by the medical imaging system to further obtain a final radiological image of the region of interest without the markers.
An imaging system for obtaining at least one final radiological image of a region of interest in a patient linearly combined from at least two radiological images, wherein at least one marker is arranged on and/or around the patient at the time the at least two radiological images are obtained, the imaging system comprising:
- a support configured to receive a patient to be examined;
- a source configured to emit an X-ray beam, wherein the source is connected to a C-arm;
- a detector, connected to the C-arm, wherein the detector is arranged facing the source and wherein the detector is configured to detect the X-rays emitted by the source;
- a control unit operatively connected to the C-arm, the source, and the detector, wherein the control unit is configured to control acquisition of images by setting parameters;
- and
- a processing system configured to receive the at least two radiological images acquired by the imaging system and to linearly combine the at least two radiological images to obtain the at least one final radiological image of a region of interest without markers.
