摘要： The present invention relates to magnetically activatable inserts. In order to provide improved ways of controlling, a radiation providing seed (10) for use in radiotherapy is provided. The seed comprises a seed core (12) that is configured to generate radiation, a casing (14) providing a cavity (16), and a movable (18) insert which is guided inside the cavity. The seed core is attached to the movable insert, which is configured as a magnetic insert, such that upon applying a magnetic field with a moving component, the insert is movable relative to the casing. The insert is movable between a first position (P1) and a second position (P2). In the first position, the seed core is in a shielded arrangement within the casing, and in the second position, the seed core is in an exposed arrangement, such that in the second position, the seed provides more radiation than in the first position. The movable insert is configured to cause a movement between the first and the second position upon being moved relative to the casing. Further, the insert is a screw insert (20) that is movably hold by a threaded connection arranged along a thread axis. The screw insert is rotatable relative to the casing to cause a screw motion resulting in a movement along the thread axis. And the screw insert has a magnetization component (24) arranged transverse to the thread axis, such that upon applying a magnetic field with a rotational component, the screw insert is rotatable relative to the casing.

摘要： A spectral X-ray imaging system (100) includes an X-ray source (110) and an X-ray detector (120) that are mounted to a support structure (150). The support structure (150) is configured to rotate the X-ray source (110) and the X-ray detector (120) around two or more orthogonal axes (A - A’, B - B’). One or more processors (130) are configured to cause the system (100) to perform operations that include: generating a spectral image based on the spectral image data; and identifying, in the spectral image, a position of a first fiducial marker (180i) comprising a first material, based on a first X-ray absorption k-edge energy value (190i) of the first material.

摘要： The invention refers to providing a system that allows to reduce the computational costs when using an iterative reconstruction algorithm. The system (100) comprises a providing unit (110) for providing CT projection data, a base image generation unit (120) for generating a base image based on the projection data, a modifying unit (130) for generating a modified image, wherein an image value of a voxel of the base image is modified based on the image value of the voxel, and an image reconstruction unit (140) for reconstructing an image using an iterative reconstruction algorithm that uses the modified image as a start image. Since the modifying unit is adapted to modify the base image, the base image can be modified such as to form an optimal start image for the chosen iterative reconstruction such that a faster convergence of the iterative reconstruction can be accomplished.

摘要： The present invention relates to a rotary anode X-ray source. In addition to a primary cathode of a rotary anode X-ray tube, an auxiliary cathode is provided in the rotary anode X-ray tube. Electrons from the auxiliary cathode are focused into an area on the anode, from which X-rays cannot enter the used X-ray beam generated by the primary cathode. An emission current controlling device is used to control the electron emission of the auxiliary cathode. Thus, the voltage down-ramp for dual energy scanning is kept constant even though the primary X-ray output changes for the sake of dose modulation or during a transient of the primary electron current.

摘要： The present invention relates to magnetically activatable inserts. In order to provide improved activation of inserted implants, a drive threaded joint (1) for insertion in a body structure is provided. The drive threaded joint comprises a first part (2) provided as a thread-body for connection with a support structure, and a second part (3) provided as a drive-body for driving the first part. The thread-body has a thread (4) defining a screwing direction along a thread axis (6). The second part is mechanically connectable to the first part. The second part has a magnetic structure (7) such that a rotating movement of the second part around an axis is activatable by an appropriate magnetic field. The drive threaded joint is further arranged such that a torque energy created by said rotation of the second part is transferrable to the thread-body once the second part is rotationally mechanically connected to the first part, implying thus the driving of the thread-body.

摘要： The invention relates to an image processing device (3) comprising a data input unit (5), a processing unit (6) and a user input unit (7). The data input unit (5) is adapted for receiving volumetric medical image data (9) organized in voxels. The processing unit (6) is adapted to perform an automatic anatomical shape model segmentation (10) on the volumetric medical image data (9), yielding a mesh model. Further, the processing unit (6) performs a determination (11) of a region of interest (21) based on the mesh model and a mesh refinement (12) of the region of interest (21). The processing unit (6) also performs a projection (15) of the region of interest (21), yielding two-dimensional medical data, and a generation of a graphical representation (16) based on the two-dimensional medical data. The user input unit (7) is adapted to receive user input on any part of the graphical representation (16) and the processing unit (6) is further adapted to adjust the graphical representation (16) in dependence on the user input, so that all parts of the graphical representation (16) are kept in a consistent state.

摘要： The present invention relates to a method (1), resp. a device, system and computer-program product, for material decomposition of spectral imaging projection data. The method comprises receiving (2) projection data acquired by a spectral imaging system and reducing (3) noise in the projection data by combining corresponding spectral values for different projection rays to obtain noise-reduced projection data. The method comprises applying (6) a first projection-domain material decomposition algorithm to the noise-reduced projection data to obtain a first set of material path length estimates, and applying (7) a second projection-domain material decomposition algorithm to the projection data to obtain a second set of material path length estimates. The second projection-domain material decomposition algorithm comprises an optimization that penalizes a deviation between the second set of material path length estimates being optimized and the first set of material path length estimates.

摘要： The present invention relates to multispectral imaging. In order to improve an identification of relevant multispectral material transitions (in particular caused by injected contrast agent), an apparatus is proposed to use the local maxima of the variances and/or covariances of the intensities of the multi-channel images to locate material transitions. In comparison to gradient vectors, the local variance is not directed and not prone to noise.An alternative apparatus is proposed to use the local covariance deficits of the intensities of the multi-channel images to locate material transitions. The proposed alternative approach is independent of spatial drifts across the image volume.
