An X-ray diagnostic apparatus according to an embodiment has a display configured to superimpose and display a plurality of X-ray irradiation ranges for generating a long range X-ray image on an image indicating a subject; and a display controller configured to change, based on an operation of a user, a position of an overlap region which is displayed on the display and at which the X-ray irradiation ranges which are adjacent to each other are overlapped.

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.

A method of tracking motion of a body part, the method comprising: (a) gathering motion data from a body part repositioned within a range of motion, the body part having mounted thereto a motion sensor; (b) gathering a plurality of radiographic images taken of the body part while the body part is in different positions within the range of motion, the plurality of radiographic images having the body part and the motion sensor within a field of view; and, (c) constructing a virtual three dimensional model of the body part from the plurality of radiographic images using a structure of the motion sensor identifiable within at least two of the plurality of radiographic images to calibrate the radiographic images.

A method includes obtaining a first imaging scan and a second imaging scan of a single subject brain. The first imaging scan is converted to a first dataset, and the second imaging scan is converted to a second dataset. A sequence-adaptive multimodal segmentation algorithm is applied to the first dataset and the second dataset. The sequence-adaptive multimodal segmentation algorithm performs automatic intensity-based tissue classification to generate a first labelled dataset and a second labeled dataset. The first labeled dataset and the second labeled dataset are automatically co-registered to each other to generate a transformation matrix based on the first labeled dataset and the second labeled dataset. The transformation matrix is applied to align the first dataset and the second dataset.

A hierarchical workflow is configured to associate examination information captured using an imaging platform with contextual metadata. The examination information may include ultrasound image data, which may be associated with annotations, measurements, pathology, body markers, and/or the like. The hierarchical workflow may comprise templates associated with respective anatomical regions, locations, volumes, and/or surfaces. A template may define configuration data to automatically adapt the imaging platform to capture imaging data in the corresponding anatomical region. The template may further include guidance information for the operator, including processing steps for capturing relevant examination information. Additional examination information may be captured and included in the hierarchical workflow.

An x-ray imaging apparatus and associated methods are provided to receive measured projection data in a primary region and measured scatter data in asymmetrical shadow regions and determine an estimated scatter in the primary region based on the measured scatter data in the shadow region(s). The asymmetric shadow regions can be controlled by adjusting the position of the beam aperture center on the readout area of the detector. Penumbra data may also be used to estimate scatter in the primary region.

This application discloses a method and apparatus for Adaptive Radiation Therapy (ART) based on plan library invoking. The method includes: acquiring a medical image of the day and a target plan library of a target patient, where the target plan library includes a plurality of groups of images of the target patient and a radiation therapy plan corresponding to each set of images; and determining the radiation therapy plan corresponding to the target patient according to the medical image of the day and the target plan library. According to this application, a problem that high-speed ART cannot be achieved due to excessive time consumption during the designing of the radiation therapy plan in the related art is resolved.

An imaging system that is configured to automatically obtain and provide two and three-dimensional digital images of various types of objects (e.g., tissue specimens, animals, electrical devices, etc.) for use in analysis thereof in a manner free of manual repositioning of the objects between images and free of movement of an electromagnetic radiation source and detector within or relative to a cabinet housing of the system.

A medical image processing apparatus having a processor configured to detect at least four reference landmarks among the left eye, the right eye, the diencephalon, the fornix, the corpus callosum, the left hippocampus, and the right hippocampus from a brain image, performs first registration including registration by similarity transformation using reference landmarks between the brain image and a standard brain image, and perform second registration by nonlinear transformation between the brain image and the standard brain image after the first registration.

A biomagnetic measuring apparatus includes a biomagnetic detector, a first marker configured to be detectable by the biomagnetic detector, a radiation source, a radiation detector provided to face the radiation source, and a second marker configured such that an image of the second marker can be captured by the radiation source and the radiation detector. Positional information about the first marker and the second marker is known or obtainable.
