摘要： A method and system for determining a PET image of the scan volume based on one or more PET sub-images is provided. The method may include determining a scan volume of a subject supported by a scan table; dividing the scan volume into one or more scan regions; for each scan region of the one or more scan regions, determining whether there is a physiological motion in the scan region; generating, based on a result of the determination, a PET sub-image of the scan region based on first PET data of the scan region acquired in a first mode or based, at least in part, on second PET data of the scan region acquired in a second mode; and generating a PET image of the scan volume based on one or more PET sub-images.

摘要： A system (SYS) and related method for facilitating collimator adjustment in X-ray imaging or a radiation therapy delivery. The system comprises an input interface (IN) for receiving input data including i) an input image and/or ii) user input data including a partial collimator setting for a collimator (COL) of an X-ray imaging apparatus (IA). A collimator setting estimator (CSE) of the system computes a complemented collimator setting for the collimator based the input data. Preferably, the system uses machine learning.

摘要： A CT apparatus includes an annular frame that rotates around a subject positioned in a bore, three columns that hold the frame to be rotatable and movable up and down in a vertical, an elevation mechanism that moves up and down the frame, and a rotation mechanism that rotates the frame. A radiation source and a radiation detector are attached to the frame at positions facing each other. The frame has a width smaller than a width of the radiation source and the radiation detector in a height direction over a whole periphery. An imaging controller performs control for operating the elevation mechanism in response to a return instruction from an operator to move the frame to a retreat height position set at a position of a highest point in an elevation range of the frame on an upper end side of the columns. The imaging controller performs control for operating the rotation mechanism in response to the return instruction from the operator to rotate the frame to a position of 60° that is a first rotation position where the radiation source overlaps the columns.

摘要： Examples of the present disclosure describe systems and methods for using machine learning (ML) to predict optimal exposure technique for acquiring mammographic images. In aspects, training data may be collected from one or more data sources. The training data may comprise sample data of patient attribute data and sample image attribute data, image metadata, image pixel data, and/or exposure technique parameters. The training data may be used to train an ML model to determine the optimal exposure technique parameters for acquiring mammographic images of a patient. After the ML model has been trained, patient data that is collected from a patient during a patient visit may be provided as input to the ML model. The ML model may output optimal exposure technique parameters for the patient in real-time. The real-time output of the ML model may be used to generate one or more mammographic images of the patient.

摘要： A method of imaging a breast of a patient with a breast imaging system includes supporting the breast on a breast support platform. A compressive force is applied to the breast with a breast immobilization element including a rigid substrate, a foam compressive element secured below the rigid substrate, and a force sensor. The foam compressive element is in contact with the breast during application of the compressive force. A force signal is detected at the force sensor based on the applied compressive force. A compressed thickness of the breast proximate the force sensor is determined based at least in part on the detected force signal at the force sensor. An automatic exposure control is set based at least in part on the determined thickness of the breast proximate the force sensor.

摘要： The invention relates to a control module for controlling an x-ray system (140) during the acquisition of step images for phase imaging. The control module comprises a step image quantity providing unit (111) for providing a step image quantity, a detector dose providing unit (112) for providing a target detector dose, an applied detector dose determination unit (113) for determining an applied detector dose absorbed by a part of the detector (144) during the acquisition of a step image, and a step image acquisition control unit (114) for controlling the x-ray imaging system (140) during the acquisition of each step image based on the applied detector dose, the target detector dose and the step image quantity. The control module allows to control the x-ray imaging system such that the target detector dose is not exceeded while at the same time ensuring a sufficient quality of the step images.

摘要： A radiation image capturing system includes a capturing room and a console. The capturing room includes a bucky apparatus, a radiation irradiating apparatus and a detecting unit. A plurality of portable radiation image capturing apparatuses can be loaded on the bucky apparatus. The radiation irradiating apparatus is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses. The console is associated with the capturing room and obtains capturing order information. The console allows the portable radiation image capturing apparatuses to advance to a capturing possible state when the console judges that capturing in the capturing order information is long length capturing. The console allows only one of the portable radiation image capturing apparatuses to advance to the capturing possible state when the console judges that the capturing is not the long length capturing.
