    • The invention provides for a medical instrument (100, 300, 400) comprising: a memory (110) for storing machine executable instructions (112) and a processor (106) for controlling the medical instrument. Execution of the machine executable instructions cause the processor to: receive (200) three dimensional medical image data (114) descriptive of a subject (318), wherein the three dimensional medical image data comprises voxels; receive (202) a segmentation of the three dimensional medical image data, wherein the segmentation divides the three dimensional image data into non-tumor voxels (700) and tumor voxels (500); choose (204) a center point (118) of the tumor voxels; divide (206) the tumor voxels into multiple groups (120) using a set of orthogonal planes (502, 504, 600), wherein the center point is within each of the orthogonal planes; calculate (208) at least one group radiomic feature (122) selected from a set of radiomic features for each of the multiple voxel groups; compute (210) a statistical measure (124) for each of the at least one group radiomic feature; calculate (212) a scalar value (128) by calculating the sum of each statistical measure multiplied by a predetermined group weighting value (126), wherein the predetermined group weighting value is unique for each statistical measure; and provide (214) a signal using a signaling interface device (108, 402) if the scalar value is above a predetermined threshold (130).

    • The invention provides for a medical imaging system (100) for acquiring medical image data (144) from an imaging zone (108). The medical imaging system comprises a memory (134) for storing machine executable instructions (140) and medical imaging system commands (142). The medical imaging system commands are configured for controlling the medical imaging system to acquire the medical image data according to a medical imaging protocol. The medical imaging system further comprises a user interface (132). The medical imaging system further comprises a processor (130) for controlling the medical imaging system. Execution of the machine executable instructions cause the processor to: receive (500) scan parameter data (146) for modifying the behavior of the medical imaging system commands; receive (502) metadata (148) descriptive of imaging conditions from the user interface; store (504) configuration data (150, 250, 252, 254) descriptive of a current configuration of the medical imaging system in the memory; calculate (506) an error probability (152) by comparing the metadata, the configuration data, and the scan parameter data using a predefined model (154), wherein the error probability is descriptive of a deviation between the metadata and between the configuration data and/or the scan parameter data; perform (508) a predefined action (158) if the error probability is above a predetermined threshold (156), wherein the predetermined action comprises providing a signal (302) to notify the user; control (510) the medical imaging system to acquire the medical image data from a subject (118); receive (512) a response (160) to the signal from the user interface in response to the signal; and reconstruct (514) one or more medical images (162) from the medical image data in accordance with the response.

    • 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.
    • 本发明涉及可磁性激活的插入件。 为了提供对插入的植入物的改进的激活,提供了用于插入身体结构中的驱动螺纹接头(1)。 驱动螺纹接头包括作为用于与支撑结构连接的螺纹体的第一部分(2)和作为驱动第一部分的驱动体而设置的第二部分(3)。 该线主体具有限定沿着螺纹轴线(6)的螺纹方向的螺纹(4)。 第二部分机械连接到第一部分。 第二部分具有磁结构(7),使得第二部分围绕轴线的旋转运动可通过适当的磁场激活。 驱动螺纹接头进一步布置成使得一旦第二部分旋转地机械地连接到第一部分,由第二部分的所述旋转产生的扭矩能量就可传递到螺纹体,这意味着驱动螺纹体。

    • 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.
