Abstract: In order to generate annotated ground truth data for training a machine learning model for inferring a desired scan configuration of an medical imaging system from an observed workflow scene during exam preparation, a system is provided that comprises a sensor data interface configured to access a measurement image of a patient positioned for an imaging examination. The measurement image is generated on the basis of sensor data obtained from a sensor arrangement, which has a field of view including at least part of an area, where the patient is positioned for imaging. The system further comprises a medical image data interface configured to access a medical image of the patient obtained from a medical imaging apparatus during the imaging examination. The patient is positioned in a given geometry with respect to a reference coordinate system of the medical imaging apparatus. The system further comprises an exam metadata interface configured to access exam metadata of the imaging examination. The system further comprises a processing unit, configured to determine an association between one or more features in the measurement image and one or more features extracted from the medical image and/or from the exam metadata by mapping a point in a coordinate system of the medical image to a point in a coordinate system of the measurement image. The system further comprises an output interface, configured to be coupled to a training set database for adding the measurement image comprising data that labels the one or more associated features in the measurement image to the training set database for training the machine learning model.

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: An imaging system is for capturing images of a patient during a medical scan. A set of one or more cameras captures images of the patient such that, after applying distortion and perspective correction steps, pixel rows correspond to locations along an axis parallel to the direction of patient support movement and pixel columns correspond to locations along an axis perpendicular to the patient support. Patient motion of interest can then be identified based on image movements in the pixel column direction between sequential captured images. A measure of patient motion can then be derived.

Abstract: Methods related to survey scanning in diagnostic medical imaging. At least one aspect relates to a method for generating, using a machine learning model, a simulation of medical image data in accordance with a defined set of acquisition parameters for a medical imaging apparatus, based on processing of an initial 3D image data set (e.g. a survey image dataset).

Abstract: The present invention relates to chest radiography. In order to improve image quality and consistency, there is provided a breathing status determination device, which comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive a sequence of depth images that is continuously captured with a sensor having a field of view covering a torso of a patient positioned for a chest radiography image examination. The processing unit is configured to analyse the received sequence of depth images to determine a change of depth values inside one or more region-of-interests (ROIs) overtime that represents a respiratory motion of the patient, and to determine a breathing signal based on the determined change of depth values inside the one or more ROIs over time. The output unit is configured to provide the determined breathing signal.

Abstract: The present invention relates to assisting scapula positioning in chest X-ray imaging. Provided is a system and related method for assisting subject positioning in chest X-ray imaging, wherein the system comprises an optical detection device (110), a user interface (130), and a processor (120), connected to the optical detection device (110) and the user interface (130). Thereby, the processor (120) is configured to receive an optical image signal of a rear view of the subject(S), determine a current positioning of a scapula of the subject(S) based on the optical image signal, wherein the current positioning of the scapula is assessed as to whether and/or to which extent it would overlap or would not overlap a lung field of the subject to be imaged and determine a feedback for positioning the subject(S) and/or its scapula based on the determined current positioning of the scapula. The user interface (130) is configured to provide the feedback for positioning the subject.

Abstract: A computer-implemented method is provided for estimating a weight of a patient when supported on a patient table. Optical image data and depth image data are obtained and patient body keypoints are extracted from the optical image data. A first frame is selected which comprises an image of the patient table, by selecting a frame in which no body keypoints are present in the optical image data. A second frame is selected of the patient on the table, by selecting a frame with patient body keypoints and with little or no movement. A patient volume is obtained based on a difference between the depth image data for the first and second frame (or depth data at those times) and the patient weight is estimated from the determined patient volume.

Abstract: A method is provided of obtaining body depth information for a patient who is lying on patient support. A patient support depth map of the upper surface of the patient support is obtained without the patient as well as an image and patient depth map of the patient on the patient support. Landmark body positions of the patient are extracted from the image so that points in a region of interest can be mapped to points of a template, using the identified landmark body positions. A body thickness is obtained for said points using the template, the depth value for the respective point and the patient support depth value for the respective point.
