An imaging apparatus includes a camera to capture a camera image of a target disposed on an examination table; an X-ray source to generate and radiate X-rays; a memory to store imaging protocols; a display; and a controller. The controller is configured to receive information regarding a selection of an imaging protocol, identify a position of an imaging region of the target based on the camera image, the imaging region corresponding to the selection of the imaging protocol and the camera image being acquired with the examination table at a first distance from the X-ray source, control the display to display the camera image of the target and an indicator indicating the imaging region on the camera image based on the identified position, and control the X-ray source to radiate the X-rays toward the target disposed on the examination table at a second distance from the X-ray source.
RADIOGRAPHIC IMAGING APPARATUS, IMAGE GENERATION METHOD, RADIOGRAPHIC IMAGING SYSTEM, AND RECORDING MEDIUM
A radiographic imaging apparatus in which a radiation source, a plurality of gratings and a radiation detector are provided side by side in a radiation irradiation axis direction includes a hardware processor. The hardware processor generates a reconstructed image on the basis of a Moire fringe image obtained by performing imaging by irradiating a subject disposed at a position overlapping the radiation irradiation axis direction with radiation by the radiation source, acquires relative position information that is relative positions in two or more dimensions of the subject with respect to the gratings, and associates the reconstructed image with the relative position information.
IMAGING SYSTEM FOR IMAGING AN ELONGATED REGION OF INTEREST OF AN OBJECT
The invention relates to an imaging system (10) for imaging an elongated region of interest of an object, an imaging method for imaging an elongated region of interest of an object, a computer program element for controlling such system for performing such method and a computer readable medium having stored such computer program element. The imaging system (10) comprises an acquisition unit (11) and a processing unit (13). The acquisition unit (11) is a C-arm acquisition unit and configured to acquire first image data of the object to be imaged with a first imaging parameter. The acquisition unit (11) is further configured to acquire second, different image data of an object to be imaged with a second imaging parameter. The second geometric imaging parameter is defined based on object specific data for the volume data to be aligned with the elongated region of interest of the object to be imaged. The processing unit (13) is configured to combine the first and second image data into volume data.
System and method for generating a 2D image using mammography and/or tomosynthesis image data
The invention includes a method including the steps of obtaining a plurality of images, each of the images in the plurality having at least one corresponding region, generating a merged image, the merged image also having the corresponding region. The step of generating includes selecting an image source from the plurality of images to source image data for the corresponding region in the merged image by comparing attributes of the corresponding regions of the plurality of images to identify the image source having preferred attributes.
COMPUTED TOMOGRAPHY SYSTEM
The invention relates to a computed tomography system (30). Several sets of spectral projections, which correspond to different positions of a radiation source (2) along a rotation axis (R), are decomposed into first projections being indicative of a contrast agent and second projections being not indicative of the contrast agent. An image is generated by a) determining for each first projection a contrast value being indicative of a total amount of contrast agent and scaling the first projections such that for different first projections of a same set the same contrast value is determined, and reconstructing an image based on the scaled first projections, and/or b) reconstructing for the different sets first images, scaling the first images such that they have a same intensity in overlap regions and combining the scaled first images. Thus, different contrast agent amounts can be balanced, thereby allowing for an improved image quality.
RADIATION IMAGE PROCESSING DEVICE, RADIATION IMAGE PROCESSING METHOD, AND RADIATION IMAGE PROCESSING PROGRAM
A processor derives a bone part image of a subject including a bone part based on a first radiation image and a second radiation image acquired by imaging the subject with radiation having different energy distributions, derives a fat percentage distribution or a muscle percentage distribution of the subject based on the first radiation image and the second radiation image, and derives a bone density in a bone region of the subject based on the bone part image, and the fat percentage distribution or the muscle percentage distribution.
System And Methods For Assessing Presence Of Large Vessel Occlusion To Aid In Transfer Decision-Making For Endovascular Treatment In Patients With Acute Ischemic Stroke
The invention relates to systems and methods to assist physicians in decision making for stroke patients. In particular the systems and methods can be used to assist physicians to decide on whether a patient with an acute ischemic stroke has a large vessel occlusion (LVO) and should be transferred from a community hospital to a larger hospital to undergo an endovascular thrombectomy procedure.
METHODS AND SYSTEMS FOR IMAGE REGISTRATION
Various methods and systems are provided for automatically registering and stitching images. In one example, a method includes entering a first image of a subject and a second image of the subject to a model trained to output a transformation matrix based on the first image and the second image, where the model is trained with a plurality of training data sets, each training data set including a pair of images, a mask indicating a region of interest (ROI), and associated ground truth, automatically stitching together the first image and the second image based on the transformation matrix to form a stitched image, and outputting the stitched image for display on a display device and/or storing the stitched image in memory.
