    Abstract: Disclosed herein is a medical system (100, 300) comprising a memory (110) storing machine executable instructions (120) and an anatomical keypoint locator module (122). The anatomical keypoint locator module is configured to output a set of anatomical keypoint coordinates (126) of a subject (318) in response to receiving a camera image (124) descriptive of the subject. The medical system further comprises a computational system (104). Execution of the machine executable instructions causes the computational system to: receive (200) the camera image; receive (202) the set of anatomical keypoint coordinates in response to inputting the camera image into the anatomical keypoint locator module; receive (204) a list of coordinates (128); search (206) the list of coordinates to determine a match with the set of anatomical keypoint coordinates: and provide (208) a warning signal if the match is determined.

    Abstract: The invention provides for a medical instrument (100, 300) comprising: a subject support (110) comprising a support surface (112); a camera system (118); and a signal system (148). The execution of the machine executable instructions (152) cause a processor (142) controlling the medical instrument to: receive (400) a list of selected objects (160) each with a selected coordinate (162); and signal (402) the list of selected objects. The Execution of the machine executable instructions further causes the processor to repeatedly: acquire (404) the camera data using the camera system; input (406) the camera data into a neural network to generate a list of placed objects (166); determine (408) a list of missing objects (168) by comparing the list of selected objects to the list of placed objects; indicate (410) using the signal system the list of missing objects; determine (412) a list of misplaced objects (170) by comparing the selected coordinate for each of the list of objects to the coordinates of the placed objects on the support surface; and indicate (414) using the signal system the list of misplaced objects.

    Abstract: It is an object of the invention to provide for an improved method for device localization using magnetic resonance imaging (MRI) during MRI guided interventions. This object is achieved by a method for device localization using magnetic resonance imaging (MRI) from a region of interest during an MRI guided intervention, wherein the method comprises the following steps: acquiring magnetic resonance data from the region of interest and reconstructing a biplane image, representing two intersecting slices, wherein an image contrast of the biplane image is such that it is suitable for device localization and wherein a thickness of the slices is such that the slices substantially cover the region of interest and; detecting a device location and orientation in both slices and; acquiring magnetic resonance data from a third slice comprising at least part of the region of interest and reconstructing an anatomical image thereof, wherein the image contrast of the anatomical image is such that it is suitable for identifying an anatomical structure of interest, wherein a thickness of the third slice is smaller than the thickness of the biplane slices.

    Abstract: The invention provides for a medical apparatus (200, 300, 400) comprising: a magnetic resonance imaging system (202), a display (270), a processor (228), and a memory (234) for storing instructions for the processor. The instructions causes the processor to receive a brachytherapy treatment plan (240), acquire (100) planning magnetic resonance data (244), calculate (102) a catheter placement positions (246, 900, 902) and a catheter control commands (248) the brachytherapy catheters. The instructions cause the processor, for each catheter placement position, to repeatedly: acquire (106) guidance magnetic resonance data (250), reconstruct (108) an image (252, 500), display (110) the image and the catheter placement position on the display, receive (114) a catheter inserted signal from a user interface, segment (116) the image to determine the catheter placement position after receiving the catheter inserted signal, recalculate (116) the catheter placement positions for each remaining catheter placement position after receiving the catheter inserted signal, and recalculate (116) the catheter control command for all of the multiple catheters after receiving the catheter inserted signal.
