Collimator
An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.
3D-beam modulation filter for equalizing dose and image quality in breast CT
A size and/or shape specific 3D-beam modulation filter and a size and/or shape specific immobilizer are provided for cone-beam breast computed tomography (bCT). The immobilizer places the breast on an optimal position in the field of view of the scanner system and the 3D-beam modulation filter modulates the incident x-ray beam in the cone-angle (i.e. z-axis of the detector panel) and fan angle (i.e. x-axis of the detector panel) directions in order to improve equalization of the photon fluence incident upon the detector panel and reduce unnecessary radiation dose that the breast receives. Both the immobilizer and the 3D-beam modulation filter are selected among a plurality of alternatives based on the specific shape, size and/or shape or size of the person's breast.
Determining a competency relationship, setting dose-related recording parameter using competency relationship
A method for determining at least one competency relationship to be used as a basis for selection of a dose-related recording parameter for an examination process, in particular the recording of a timed series of x-ray images as an x-ray image dataset, of a patient at an x-ray device, between at least one competency value describing a user-specific or user-group specific user competency in respect of the evaluation of recorded x-ray images and at least the at least one recording parameter. The method includes displaying a plurality of x-ray image datasets corresponding to different recording parameters and/or having different image contents described by image content parameters; recording, for each x-ray image dataset, at least one measured value describing the competency value based on an interaction of a user with an operating device assigned to a display device; and determining, based on the measured values, the competency relationship describing the recording parameter-dependent competency value.
X-ray imaging system and method
Disclosed are an X-ray imaging system and method, and the system comprises an X-ray source, a high-voltage generator, a collimator, a digital flat-panel detector, and a host computer; a position relationship between a projection area and a subject is visually displayed through a display screen; as an image frame on the screen is directly dragged to a corresponding position of an image of the subject presented on the screen or an area of interest is drawn, the collimator automatically drives a collimating sheet to move and enables the projection area to move to an observation position required by the subject, and information about the area of interest is transmitted to the detector as an input for selecting a response area of automatic exposure control (AEC). The collimator cooperates with digital automatic exposure control (DAEC), so that a strict requirement is no longer existent for patient positioning.
SYSTEMS AND METHODS FOR TAKING X-RAY IMAGES
The present disclosure relates to systems and methods for imaging. The method may include: obtaining reference data associated with an object; determining, based on the reference data, at least one of a start point or an end point of an imaging region associated with the object; causing an acquisition device to take an X-ray image of the imaging region based on at least one of the start point or the end point; and transmitting a control signal to cause an indicating device to present at least one of the start point or the end point while taking the X-ray image, wherein the indicating device includes a laser indicating device, the laser indicating device including an emitting unit and a receiving unit, the receiving unit synchronously moving with the emitting unit.
SYSTEM AND METHOD FOR SUBJECT SHAPE ESTIMATION
A medical imaging system is provided. Imaging detector columns are installed in a gantry to receive imaging information about a subject. Imaging detector columns can extend and retract radially as well as be rotated orbitally around the gantry. The system can automatically adjust setup configuration and an imaging operation based on subject shape estimation information.
RADIOGRAPHIC SYSTEM
The radiographic system includes a camera that images a subject, a processor, and a display, in which the processor recognizes whether or not arrangement of the subject in a camera image captured using the camera matches arrangement of the subject in the imaging menu, and displays a first display mode for indicating presence of a result of the recognition, and displays a second display mode for displaying a content of the recognition result in a case of receiving an explicit display request for the recognition result, on the display.
X-Ray Apparatus And Patient Instruction System
An X-ray apparatus and patient instruction system for easily instructing patients through an X-ray procedure in a variety of languages includes an X-ray apparatus, a computer, and a controller. The X-ray apparatus comprises an X-ray generator coupled within an X-ray housing to create a digital X-ray image. An X-ray CPU and a speaker are coupled within the X-ray housing. The computer comprises a computer CPU coupled within the computer housing. The computer CPU is in operational communication with the X-ray CPU stores a plurality of audio recordings of X-ray procedure instructions to play through the speaker. A computer display shows the digital X-ray images from the X-ray generator. The controller comprises a control button coupled to the controller handle to operate the speaker and the X-ray generator.
METHODS AND APPARATUS FOR EXTENDED LOW CONTRAST DETECTABILITY FOR RADIOGRAPHIC IMAGING SYSTEMS
