    Abstract: An interventional X-ray system (10), comprises a processing unit (30), a table (20) for receiving a patient (44), an X-ray image acquisition device (12) having an X-ray source (16) and an X-ray detector (18) and at least one optical camera (46) adapted for acquiring optical images of a patient (44) situated on the table (20) and for providing image data to the processing unit (30). The processing unit (30) is adapted for segmenting an outline (64) of a patient from an existing three-dimensional model, for receiving acquired images from the at least one camera (46) for determining an optical outline (66) of the patient, for registering the optical outline (66) to the outline (64) obtained in the segmentation and for determining a translation vector (48) representing a required movement of the table for coinciding a center (42) of the anatomy of interest given in the three-dimensional model with the iso-center (38) of a rotational X-ray scan that will be performed. By this process, no X-ray exposure or injection of contrast agent is required.

    Abstract: The invention relates to an imaging system (10) for imaging an elongated region of interest of an object, an imaging method for imaging an elongated region of interest of an object, a computer program element for controlling such system for performing such method and a computer readable medium having stored such computer program element. The imaging system (10) comprises an acquisition unit (11) and a processing unit (13). The acquisition unit (11) is a C-arm acquisition unit and configured to acquire first image data of the object to be imaged with a first imaging parameter. The acquisition unit (11) is further configured to acquire second, different image data of an object to be imaged with a second imaging parameter. The second geometric imaging parameter is defined based on object specific data for the volume data to be aligned with the elongated region of interest of the object to be imaged. The processing unit (13) is configured to combine the first and second image data into volume data.

    Abstract: The present invention relates to a guidance device (10) for a TEE probe (20), a medical imaging system (1), a method for guiding a TEE probe (20), a computer program element for controlling such device and a computer readable medium having stored such computer program element. The guidance device (10) for a TEE probe (20) comprises an image data provision unit (11), and a processing unit (12). The image data provision unit (11) is configured to provide first image data showing an interventional device (40) and a TEE probe (20) in an initial position and orientation. The processing unit (12) is configured to determine a center-line of the interventional device (40)in the first image data. The processing unit (12) is configured to determine a plane (41) orthogonal to a tangent of the centerline as viewing plane. The processing unit (12) is configured to calculate an imaging plane and an imaging orientation of the TEE probe (20) to lie approximately in the viewing plane. The processing unit (12) is configured to provide the calculated data as guidance data.

    Abstract: A system (100) for reconstructing digital subtraction angiography, DSA, images (110) representing a region of interest (120) in an object (130), is provided. The system includes one or more processors (140) configured to: receive (S110) cone beam projection data (150) acquired during a portion of a revolution of a source-detector arrangement (160s, 160d) of a cone beam X-ray imaging system (170) around the object (130); reconstruct (S120) the cone beam projection data (150) acquired from one or more orientations within a first angular range (Dq1), into a 3D mask image (170) representing the region of interest (120); and reconstruct (S130) the cone beam projection data (150) acquired from one or more orientations within a second angular range (Dq2), into a temporal sequence of 3D DSA images (110) representing the region of interest (120), based on the reconstructed 3D mask image (170).

    Abstract: An imaging system (MIS), optionally a medical imaging system, with wireless communication capability and related method. The imaging system comprises a gantry (RG) rotatable around a rotation axis. The gantry includes a detector device (D) capable of recording, in plural spatial positions, measurement data in relation to a subject (such as a patient) (PAT) to be imaged. The system also includes a radio transmitter (TX) for generating a directed radio beam propagatable along a propagation axis to transmit the measurement data to a radio receiver (RX). The radio transmitter (TX) is arranged at the rotatable gantry and is operable so that the propagation direction intersects the rotation axis in a location that is situated away from the rotatable gantry.
