Abstract: The disclosed method encompasses moving an object such as a medical device or instrument to a desired spatial position based on tracking data provided by a tracking system. Once it is determined from the tracking data that the object has reached the desired spatial position, a projection image is generated, which is registered with the desired spatial position and shows the object. Based on the image data, it is possible to verify whether the object has actually reached the desired position, or whether the object's actual position deviates from the desired position due to errors or inaccuracies, allowing measures to be taken to compensate for these errors or inaccuracies.

Abstract: Provided is a computer-implemented method for assessing a medical image of an object imaged with an X-ray system. The method proposes to generate one or more positioning data sets, which differ in at least one positioning parameter. The X-ray system images medical images of the object with the one or more positioning data sets. The obtained medical images were assessed by measuring a quality measure in the medical images and comparing the measured quality measures with an evaluation criterion. A positive assessed medical image with the corresponding positioning data is then provided for further processing.
