A method for determining the position and/or orientation of at least one sensor system relative to the base structure of a scanning system during scanning of an object, the method includes obtaining one or more tracking images using one or more cameras, where the cameras are in a fixed position with respect to the sensor system; and determining from the one or more tracking images the position and/or orientation of the sensor system relative to the base structure at a given time.

A weightbearing simulation assembly includes a substrate comprising a mounting surface extending in a first direction a subject support disposed on a first region of the mounting surface and a pedal assembly disposed on a second region of the mounting surface. The pedal assembly includes a spring assembly including a contact plate facing the subject support, a compression plate, and a first spring disposed between the contact plate and the compression plate. A subject applies a compressive force to the contact plate in a compression direction to simulate a load-bearing condition by compressing the first spring. An orientation of the pedal assembly may be adjusted to change a relative angle between the compression direction and the first direction to alter an imaging angle.

A CPU acquires a radiographic image obtained by imaging an imaging region where a patient is present, with a radioscopy apparatus using radiation emitted from a radiation source and applied to an irradiation field adjusted by a collimator. The CPU specifies a structure image that is included in the radiographic image and represents a structure of a specific shape having transmittance of radiation lower than the patient, based on the specific shape. The CPU executes image processing corresponding to the structure image on a patient image region imaged by a radioscopy apparatus in a case where an irradiation field excluding a position of the structure is set as the irradiation field, in a region in the radiographic image.

A console includes a CPU as at least one processor. The CPU acquires a radiographic image obtained by imaging an imaging region where a patient is present, with a radioscopy apparatus. The CPU specifies a structure image that is included in the radiographic image and represents a structure of a specific shape having transmittance of radiation lower than the patient, based on the specific shape. The CPU executes image processing corresponding to the structure image to the radiographic image.

Various methods and systems are provided for a set of devices for an imaging system. In one example, the set of devices includes a first device configured to obtain a first set of image data and a second device configured to obtain a second set of image data along at least one dimension. The first and second sets of data may be compiled to generate a field-of-view (FOV) preview.

A system for register operating space includes a first positioning mark, a local camera, a second positioning mark, a global camera and a computer system. The first positioning mark is set on a patient. The local camera captures a first image covering the first positioning mark. The second positioning mark is disposed on the local camera. The global camera captures a second image covering the second positioning mark. The focal length of the global camera is shorter than the focal length of the local camera. The computer system is communicatively connected to the local camera and the global camera to provide a navigation interface based on the first image and the second image.

A compression paddle with a plurality of markers is advanced towards a patients breast which has been positioned on a support platform for an imaging procedure. An initial position of the compression paddle is detected relative to the support platform when a portion of the breast is contacted. An initial marker is identified which is associated with a feature of the breast when the compression paddle is in the initial position. A compression target marker is based at least in part on the initial position and the initial marker.

An imaging system (100) includes a subject support (114) that supports a subject in an examination region (106). The imaging system further includes a detector (112) that detects a signal traversing the examination region, generating an output indicative of the examination region. The imaging system further includes a subject motion sensing system (118) that includes an optical system (206, 208, 214) that detects motion of the subject in the examination region and generates motion data indicative thereof. The imaging system further includes a console (122) that controls at least one of data acquisition or reconstruction based on the motion data.

Certain exemplary method and/or apparatus embodiments herein can include—a support frame, —a movable gantry that supports an x-ray source and an x-ray sensor in correspondence with the x-ray source and that is movable relative to the support frame, —a patient positioning accessory support member configured to support a patient positioning accessory of a specific type that is adapted to be used in the apparatus for conducting a specific examination on a patient, where the patient positioning accessory comprises at least one passive identification element that identifies the specific type of the patient positioning accessory, and the apparatus further comprises an active identification system that is configured to cooperate with the at least one passive identification element of the patient positioning accessory in order to identify the specific type of the patient positioning accessory.

A method for improving the accuracy of a digital medical model of a part of a patient, the method includes obtaining a set of at least 2 medical images of the patient, where an element including a predefined geometry and/or predefined information was attached to the patient during the recording of the medical images; obtaining at least 2 tracking images taken with at least one camera having a known positional relationship relative to the medical imaging device, the tracking images depicting at least part of the element; determining any movement of the element between acquisition of the at least 2 tracking images; and generating the digital medical model from the acquired medical images, wherein the determined movement of the element is used to compensate for any movement of the patient between the acquisition of the medical images.
