A rotational position determination apparatus is configured to determine an entry rotational position, which defines a rotational position of an insertion device like a stent at an entry site, such that a navigation of the insertion device from the entry site to a target site along an inner path results in a rotational position of the insertion device at the target site being equal to a desired target rotational position based on a representation of the inner path and the desired target rotational position. If the insertion device is arranged in the determined entry rotational position at the entry site and then navigated to the target site, it is therefore not necessary to rotate the insertion device at the target site.

The invention relates to a combined imaging detector for detection of gamma and x-ray quanta comprising an x-ray detector () for generating x-ray detection signals in response to detected x-ray quanta and a gamma detector () for generating gamma detection signals in response to detected gamma quanta. The x-ray detector () and the gamma detector () are arranged in a stacked configuration along a radiation-receiving direction (). The gamma detector () comprises a gamma collimator plate () comprising a plurality of pinholes (), and a gamma conversion layer () for converting detected gamma quanta into gamma detection signals.

A computing device includes a thermal map generator () that generates a thermal map for image data voxels or pixels representing a volume or region of interest of a subject based on thermometry image data, which includes voxels or pixels indicating a change in a temperature in the volume or region of interest, and a predetermined change in value to temperature lookup table () and a display () that visually presents the thermal map in connection with image data of the volume of interest. A method includes generating a thermal map for image data voxels or pixels representing a volume or region of interest of a subject based on thermometry image data, which includes voxels or pixels indicating a change in a temperature in the volume or region of interest, and a predetermined change in voxel or pixel value to temperature lookup table.

Imaging thermometry

An image processing method and related system to register projection images (AG, MI) only with respect to a motion of a landmark across said images. The motion of the landmark relates to a motion of a region of interest, ROI. The so registered images (AG, MI) are then subtracted from each other to arrive at a difference image that is locally motion compensated and that represents the ROI at good contrast while subtraction artifacts can be avoided.

A tumor targeting ablation planning device and method include providing a predetermined ablation profile and a segmented tumor to be treated in an ablation procedure. A contour of the segmented tumor is generated and the predetermined ablation profile is overlapped with a part of the segmented tumor to form an overlapping region, which is identified. Further, a predetermined safety factor is applied to at least a part of the at least one segmented tumor in the overlapping region to generate a modified overlapping region. Parts of the overlapping region that are arranged outside the modified overlapping region are determined as overlapping portions. A display is configured to: display the contour of the segmented tumor, display the predetermined ablation profile overlapped with the at least part of the segmented tumor in the overlapping region, and display the overlapping portions in relation with the contour and the ablation profile as virtual planning ablation result.
