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.

The present disclosure provides a system and method for image data acquisition. The method may include obtaining image data of a subject including a first type of tissue and a second type of tissue. The method may include determining, based on the image data of the subject, a target portion including at least a portion of at least one of the first type of tissue or the second type of tissue. The method may include determining, based at least in part on the target portion represented in the image data, a scan mode corresponding to the target portion. The method may include causing an imaging device to acquire, based on the scan mode, image data of the target portion.

Medical imaging methods for processing a three-dimensional (3D) image data set with two-dimensional X-ray images from an X-ray machine using a target function. Methods can include providing a 3D image data set of at least one examination zone in which anatomical structures are present, segmenting the image data set to provide a 3D vascular structure model and a 3D bone structure model, recording a first two-dimensional (2D) X-ray image containing at least a portion of the vascular structure and at least a portion of the bone structure, recording a second 2D X-ray image of the examination zone at a different contrast agent concentration, and subtracting the first and second 2D X-ray images to generate a subtraction image. An optimum projective geometry may then be determined using a three-part target function based on the 3D image data and the 2D X-ray images.

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

A method and apparatus for analyzing diagnostic image data are provided in which a plurality of acquisition images of a vessel of interest having been acquired with a pre-defined acquisition method is received at a trained classifying device and classified, by the classifying device, to extract at least one quantitative feature of the vessel of interest from at least one acquisition image of the plurality of acquisition images. The at least one quantitative feature is then output associated with the at least one acquisition image while the acquisition of the diagnostic image data is still in progress and one or more adjustable image acquisition settings are adjusted based on the at least one quantitative feature to optimize the acquisition of the diagnostic image data.

According to the method and the apparatus for acquiring a CBCT image based on adaptive sampling according to the exemplary embodiment of the present disclosure, a final CBCT image is acquired by reconstructing a plurality of cone beam computed tomography (CBCT) images acquired based on adaptive sampling so that a dose applied to the target patient may be reduced.

A radiation image imaging apparatus which generates an image from irradiated radiation, the radiation image imaging apparatus including: a communication unit which directly communicates by wireless communication with an information processing apparatus, which performs wireless communication, and receives installation setting information transmitted from the information processing apparatus to perform a predetermined setting at a time of an installation; and a hardware processor which performs the predetermined setting of the radiation image imaging apparatus in accordance with the installation setting information received by the communication unit.

CT scan parameters for performing a CT scan of an anatomical target region of a patient are determined and/or adjusted. An initial set of the CT scan parameters for starting to perform the CT scan is determined based on an initial set of attenuation curves associated with the anatomical target region of the patient. The initial set of attenuation curves are determined based on optical imaging data depicting the patient.

The present disclosure provides a method for automated image acquisition and imaging processing. The method may include obtaining imaging information of an object. The method may include determining, based on the imaging information, at least target device positioning information of an imaging device. The method may include causing, based on the target device positioning information of the imaging device, the imaging device to be positioned to perform the image acquisition. The method may include providing, based on the inspection information, guidance information, the guidance information being configured to guide positioning of the object. The method may also include obtaining a target image from an imaging operation by the imaging device. Further, the method may include determining a target image processing algorithm of a medical image.

In some implementations, a device may obtain scan information associated with scanning a section of a body that includes an object within tissue of the section. The device may determine a region of the section that is likely to be represented by an artifact in an image obtained using a first scanning type of a medical image device. The device may determine a plurality of scan patterns for scanning the region using a second scanning type. The device may determine, for the plurality of scan patterns, individual scan scores associated with scanning the region. The device may select, based on the individual scan scores, an optimal scan pattern from the plurality of scan patterns. The device may transmit the optimal scan pattern to the medical imaging device to permit the medical imaging device to scan the section to obtain optimized image data associated with the region.
