X-RAY IMAGING SYSTEM AND X-RAY IMAGING APPARATUS
An X-ray imaging system includes an X-ray irradiation unit, an X-ray detection unit, an imaging unit that acquires a subject image obtained by imaging an appearance of the subject, a position information acquisition unit that acquires a position information of the subject captured in the subject image, a target position acquisition unit that acquires a target position according to imaging conditions, and a projection unit that projects a marker indicating a contour of the subject for guiding a position of the subject to be the target position acquired by the target position acquisition unit, onto an imaging position that is the subject or a surface to which the subject is fixed.
CONTROL DEVICE AND CONTROL PROGRAM
A control device including: at least one processor, wherein the processor is configured to acquire inclination information indicating an inclination of an imaging surface of an imaging table in a mammography apparatus that irradiates a breast in a compressed state between the imaging surface of the imaging table and a compression member with radiation from a radiation source to capture a radiographic image and perform control to adjust information, which is displayed on a projection surface of the compression member by projection of a projection image by an image projection unit, according to the inclination indicated by the inclination information.
Automated detection of abnormal subject configuration for medical imaging
The invention provides for a medical instrument (100, 400) comprising a medical imaging system (102, 402) configured for acquiring medical imaging data (432) from a subject (108); a subject support (110) configured for supporting the subject during acquisition of the medical imaging data; and an optical imaging system (114, 114′) configured for acquiring optical imaging data (134) of the subject on the subject support. The execution of the machine executable instructions causes a processor (122) controlling the medical instrument to: control (200) the optical imaging system to acquire the optical imaging data; generate (202) the initial vector (136) using the optical imaging data; generate (204) the synthetic image by inputting the initial vector into a generator neural network; calculate (206) a difference (140) between the synthetic image and the optical imaging data; and provide (208) a warning signal (142) if the difference differs by a predetermined threshold. The generator neural network is trained to generate a synthetic image (138) of the subject on the subject support in response to inputting an initial vector.
X-ray imaging apparatus
An X-ray imaging apparatus includes a moving unit for changing an irradiation position which is a position of a subject to be irradiated with X-rays by moving at least one of an imaging unit for emitting X-rays to a subject and a top board, and a control unit for performing control for displaying on a first display unit a two-dimensional virtual plane image which is a two-dimensional image in which an image indicating the skin dose for each of a plurality of irradiation positions and a scale image indicating at least one of the distance and the angle with respect to a reference position are superimposed on a virtual plane.
Fluoroscope with movable head and barrier to vary source to skin distance
For radiation safety, a fluoroscope has an adjustable X-ray source-to-intensifier distance (SID) and an X-ray transparent spacer positioned between the source and receptor. As a distance between the source and the intensifier is changed, the spacer is moved or a different sized transparent spacer is used, to ensure a safe minimum skin-to-source distance (SSD) is maintained. A processor is programmed to inhibit the generation of X-rays if the SID is greater than a defined distance and the spacer is not in position.
AUTOMATED DETECTION OF ABNORMAL SUBJECT CONFIGURATION FOR MEDICAL IMAGING
The invention provides for a medical instrument (100, 400) comprising a medical imaging system (102, 402) configured for acquiring medical imaging data (432) from a subject (108); a subject support (110) configured for supporting the subject during acquisition of the medical imaging data; and an optical imaging system (114, 114′) configured for acquiring optical imaging data (134) of the subject on the subject support. The execution of the machine executable instructions causes a processor (122) controlling the medical instrument to: control (200) the optical imaging system to acquire the optical imaging data; generate (202) the initial vector (136) using the optical imaging data; generate (204) the synthetic image by inputting the initial vector into a generator neural network; calculate (206) a difference (140) between the synthetic image and the optical imaging data; and provide (208) a warning signal (142) if the difference differs by a predetermined threshold. The generator neural network is trained to generate a synthetic image (138) of the subject on the subject support in response to inputting an initial vector.
PROXIMITY DETECTION
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.

Iso-centering in C-arm computer tomography
An apparatus for medical imaging of a patient, including an object of interest, is provided. The apparatus comprises a patient support unit, a processor, and a display. The patient support unit is configured to receive a patient. The processor is configured to receive scout images of the patient acquired in respective positions of the apparatus. Each respective position is represented by a position parameter. The processor is further configured to select at least one iso-centering image from the scout images by geometrical calculation using the position parameter of each scout image and a position parameter representing a present position of the apparatus. The processor is further configured to adapt the appearance of the at least one iso-centering image according to the present position of the apparatus. The display is configured to present the at least one adapted iso-centering image.
IMAGING SYSTEMS AND METHODS
Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon's workflow to continue uninterrupted.
