DIFFUSIVITY CONTRAST AGENTS FOR MEDICAL IMAGING
A method for medical imaging using a diffusivity contrast agent is provided. The method includes obtaining the diffusivity contrast agent having specific diffusivity, wherein the diffusivity contrast agent is configured to pass a biological barrier of a subject; administering to the subject a detectable dose of the diffusivity contrast agent for at least one medical imaging modality, where the medical imaging modality includes one or more of MRI, PET, SPECT, CT, x-ray, optical imaging and ultrasound; acquiring one or more post-contrast images for a region of interest after the administration of the diffusivity contrast agent, wherein said post-contrast images include changes in diffusivity of the region of interest compared to one or more images acquired without said diffusivity contrast agent; and characterizing a transport of the diffusivity contrast agent in the region of interest based on the changes in diffusivity of the region of interest.
SYSTEM AND METHOD FOR MEDICAL IMAGING
The present disclosure provides a system and method for magnetic resonance imaging. The method may include obtaining reference information associated with at least two regions of interest (ROIs) of a subject. The method may also include obtaining a plurality of images associated with the at least two ROIs, the plurality of images being determined based on scanning data of the at least two ROIs generated in a single scan performed on the at least two ROIs by an imaging device. The method may further include identifying local images of each of the at least two ROIs from the plurality of images based on the reference information.
SETTING DEVICE, SETTING METHOD, AND SETTING PROGRAM
A setting device comprising at least one processor, wherein the processor is configured to: acquire imaging part information indicating an imaging part of a subject captured by a radiation emitting device; acquire body thickness information; derive target values of a tube voltage and a mAs value for emitting the radiation such that a dose of the radiation transmitted through the imaging part is the same as a dose at a reference body thickness, on the basis of the acquired body thickness information and the acquired imaging part information; and derive a set value of a tube current for obtaining the target mAs value and a set value of an irradiation time of the radiation on the basis of at least one of an upper limit value of the irradiation time, a tube current corresponding to a focus size, or a maximum output value of a tube.
Mammography apparatus and program
A mammography apparatus includes a diagnostic image acquisition unit that acquires a diagnostic image in which a calcification as a biopsy target is marked; a scout image acquisition unit that acquires a scout image obtained by imaging a mamma undergoing the biopsy from a specific direction; and a display unit that highlights a calcification (candidate for biological tissue examination) in the scout image which matches at least the marked calcification in the diagnostic image.
Dental bite block for 2D imaging
Dental radiographic imaging systems and/or methods for using the same can provide panoramic 2D dental radio-graphic images. Providing improved panoramic 2D image quality can depend on imaging a desired/selected focal trough, which is itself based on a correct positioning of the patient's head inside the panoramic dental imaging system. Exemplary dental radiographic imaging systems and/or methods for using the same can provide a patient positioning device (e.g., bite stick embodiments) that can position or urge patients to get the right positioning (such as head tilt) to increase probabilities of the improved/best panoramic image reconstruction. Further, certain exemplary bite stick embodiments can repeatedly, consistently and/or correctly position patient after patient for panoramic imaging.
IMAGING SUPPORT DEVICE, AND OPERATION METHOD AND OPERATION PROGRAM FOR THE SAME
An imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject, includes at least one processor. The processor executes a determination process of determining a necessity of and a reason for recapturing an acquired new radiation image by using a trained model that has learned a relationship between a radiation image acquired in the past and the necessity of and the reason for reimaging, a corrective measure derivation process of, in a case where it is determined that reimaging is necessary, deriving a corrective measure for correcting a position or an orientation of the subject on the basis of the reason for determining that reimaging is necessary, and a presentation process of presenting the corrective measure derived in the corrective measure derivation process.
IMAGING SUPPORT DEVICE, OPERATION METHOD FOR THE SAME AND OPERATION PROGRAM
An imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject, and includes an optical camera that outputs an optical image by optically imaging a region including an irradiation field of the radiation applied to the subject from the radiation source, and at least one processor, in which the processor executes a determination process of determining a possibility of reimaging in a case where radiography is performed on the basis of the optical image acquired by the optical camera before start of the radiography by using a trained model that has learned a relationship between the optical image captured during the radiography and a necessity of recapturing the radiation image that is captured during the radiography.
METHODS AND SYSTEMS FOR AUTOMATIC IMPLANT DETECTION IN MAMMOGRAPHY
Various methods and systems are provided for mammogram imaging. In one example, a method for an x-ray mammography system includes determining, based on a pre-exposure image of a subject acquired with the x-ray mammography system before acquisition of one or more main images, that the subject has an implant; automatically adjusting one or more imaging parameters in response to determining that the subject has the implant; and acquiring the one or more main images with the adjusted one or more imaging parameters.
RADIATION DETECTOR AND RADIOGRAPHY APPARATUS
A radiation detector includes a support table in which an attachment surface having an arc surface shape is formed, a sensor panel which has a rectangular plate shape and in which pixels that include TFTs and detect radiation are two-dimensionally arranged, a circuit board, a flexible cable, and a reduction structure. The sensor panel is attached to the attachment surface while being curved following the arc surface shape. The flexible cables connect a curved side of the sensor panel and a reading circuit board and are arranged along the curved side. The flexible cable is bent to dispose the reading circuit board at an angle of 90° with respect to the sensor panel. The reduction structure reduces a bias of a stretching force applied to the flexible cable caused by the curved side.
RADIOGRAPHY APPARATUS
A radiography apparatus includes an upright imaging stand that is used for radiography on a subject, a camera as a detection sensor that immediately detects a state of the subject with respect to the upright imaging stand, a tablet terminal, and a reflective member. The tablet terminal displays a notification screen including an image output from the camera. The reflective member reflects the notification screen such that the subject facing the upright imaging stand visually recognizes the image.
