The present disclosure is directed to systems and methods for intraoperative medical imaging A computing system may access, from a database, a first tomogram derived from scanning a volume within a subject prior to an invasive procedure. The first tomogram may identify a target within the volume of the subject. The computing system may acquire data via an endoscopic device within the subject at a time instance during the invasive procedure. The computing system may provide, for display, in the first tomogram of the subject, a first relative location of a distal end of the endoscopic device and the target based on the data. The computing system may receive a second tomogram of the volume at the time instance. The computing system may register the second tomogram with the first tomogram to determine a second relative location of the distal end and the target.

A method is provided for monitoring a flow of a fluid in a vessel of a body of a living being is provided. The method comprises obtaining a first image data set representing the vessel filled with a first fluid, the first image data set comprising at least one first image frame and the first fluid contrasting with matter surrounding the vessel and obtaining a second image data set representing the vessel substantially void of the first fluid, the second image data set comprising at least one second image frame. Based on the first image data set and the second image set, an estimated location of the vessel in the second image set is estimated; and monitoring presence in the second data set of contrasting image data at the estimated location of the vessel is monitored.

The present disclosure provides a system and method for medical imaging. The method may include obtaining a preliminary image and scanning data of a subject acquired using a scanner. The method may also include determining a regularization parameter for a regularization item of an objective function based at least in part on the scanning data, wherein the regularization parameter includes at least two of a first component characterizing quality of the scanning data, a second component characterizing the scanner, or a third component characterizing a feature of the subject. The method may further include generating an image of the subject by reconstructing the preliminary image based on the objective function.

There is provided a radiographic imaging apparatus capable of facilitating a comparative radiological interpretation of symmetric portions or a temporal comparative radiological interpretation of a same imaging target. The radiographic imaging apparatus includes an image control unit configured to cause a display unit configured to display a plurality of divided screens to display a first radiographic image of a first imaging target on a first divided screen of the plurality of divided screens. The image control unit causes a radiographic image of the first imaging target that is captured at a different time from the first radiographic image or a radiographic image of a second imaging target that is a symmetric imaging target of the first imaging target to be displayed on a second divided screen of the plurality of divided screens as a second radiographic image.

An information processing apparatus includes at least one processor that is configured to: acquire a low-energy image captured by a radiography apparatus by emitting radiation having first energy to a subject into which a contrast medium has been injected, and each of a plurality of high-energy images captured by the radiography apparatus at different timings by emitting radiation having second energy higher than the first energy to the subject into which the contrast medium has been injected, and generate a plurality of difference images showing a difference between the low-energy image and each of the plurality of high-energy images.

A control apparatus includes at least one processor that is configured to: acquire an elapsed time from injection of a contrast medium into a subject for which a radiation image is captured by a radiography apparatus, acquire a low-energy image captured by the radiography apparatus by emitting radiation having first energy to the subject into which the contrast medium has been injected, and a high-energy image captured by the radiography apparatus by emitting radiation having second energy higher than the first energy to the subject into which the contrast medium has been injected, generate a difference image showing a difference between the low-energy image and the high-energy image, and identify whether or not to perform re-capturing of the high-energy image of the subject, based on an analysis result about a contrast amount, which is performed on the difference image, and the elapsed time.

An image processing apparatus includes at least one processor that is configured to: acquire a low-energy image captured by a radiography apparatus by emitting radiation having first energy to a subject into which a contrast medium has been injected, and a plurality of high-energy images captured by the radiography apparatus by emitting radiation having second energy higher than the first energy at a plurality of different imaging timings after the injection of the contrast medium, and generate a second difference image showing a difference between a plurality of first difference images showing a difference of the low-energy image and each of the plurality of high-energy images to remove a pixel value corresponding to the contrast medium that has permeated outside a region of interest.

A medical imaging jig is provided with a foldable handle and an integral type foldable footstool, so that a patient having difficulty in movement can be easily and safely subject to medical imaging. In particular, the integral type foldable footstool is provided to be rotated on a hinge to be folded, a lead ruler provided on the rear surface of the medical imaging jig is slidably and detachably provided so that the lead ruler may be moved leftward or rightward or detached depending on the demand by a user, a handle provided on the medical imaging jig may be folded to allow positioning of an objected to be imaged, and omnidirectional wheels are provided on the lower end of the medical imaging jig.

An X-ray fluoroscopic imaging apparatus which can accurately perform enhancement processing of a device and can also reduce a burden on an operator is provided. An exclusion region E is set so as to surround an obstacle on an X-ray image generated by an image generation unit. A marker extraction unit extracts a marker from a region except for an exclusion region in the X-ray image. An integration unit superimposes a predetermined number of X-ray images on the basis of the position of the marker to generate an integrated image. In this case, detecting obstacle as a marker can be avoided, so the integrated image becomes an image with a stent suitably highlighted. Even in cases where it is difficult to set the region-of-interest so that an obstacle falls out of the range, such as a case in which an obstacle overlaps or is in proximity to a stent, it is easy to set the exclusion region so that the marker is out of range and the obstacle falls within the range. Therefore, the enhancement processing of the stent can be suitably executed according to more various situations.
