Intraoral tomosynthesis systems, methods, and computer readable media for dental imaging can include an x-ray source containing multiple focal spots spatially distributed on one or multiple anodes in an evacuated chamber, an x-ray detector for positioning inside a mouth of a patient, a device for determining imaging geometry of the intraoral tomosynthesis system; and control electronics configured to regulate the x-ray source, by sequentially activating each of the multiple focal spots, such that multiple two dimensional (2D) projection images of the mouth of the patient are acquired from multiple viewing angles. In some aspects, the device for determining the imaging geometry can comprise a plate connectedly attached to the x-ray detector, at least one light source connectedly attached to the x-ray source, and a camera configured to capture at least one light spot produced by a projection of at least one light beam onto the plate.

An x-ray breast imaging system comprising a compression paddle in which the compression paddle comprises a front wall and a bottom wall. The front wall is configured to be adjacent and face a chest wall of a patient during imaging and the bottom wall configured to be adjacent a length of a top of a compressed breast. The bottom wall extends away from the patient's chest wall, wherein the bottom wall comprises a first portion and a second portion such that the second portion is between the front wall and the first portion. The first portion is generally non- coplanar to the second portion, wherein the compression paddle is movable along a craniocaudal axis. The x-ray breast imaging system also comprises a non-rigid jacket releasably secured to the compression paddle, the non-rigid jacket positioned between the compression paddle and the patient.

The present invention provides a latching mechanism for an x-ray tube assembly comprising a rotary plate, a first spring-loaded latch and a second spring-loaded latch which are disposed diametrically. The rotary plate comprises a first receiving portion and a second receiving portion spaced from each other by 90°. The first spring-loaded latch configured to be pressed removably into the first receiving portion to lock the x-ray tube assembly in a first position and the second spring-loaded latch is configured to be pressed removably into the second receiving portion to lock the x-ray tube assembly in a second position. According to the present invention, it is possible tomake manufacturing tolerance control and assembly of the x-ray imaging system much simpler and easier.

A method, apparatus, system, and computer program for generating clinical information. Information indicating at least one clinical aspect of an object is received. Clinical information of interest relating to the at least one clinical aspect is generated from a plurality of projection images.

In the present embodiments, a statement related to an image point or an image region in a reconstructed x-ray image is made in relation to the reliability of the reconstructed grayscale value for the image points of a 2D/3D x-ray image. A confidence level is formed for the grayscale value from a first number of the available x-ray images in relation to a second number of required x-ray images for a complete reconstruction of the respective grayscale value of the 2D/3D x-ray image to be imaged.

Improved systems and devices for medical imaging distribution are provided. A medical imaging order may be received from a medical facility that includes medical imaging. A configuration may be selected and applied based on a body site and an urgency field associated with the order that defines queueing rules for the medical imaging order. Utilization factors for queues associated with radiologists may also be determined. The configuration and the utilization factors may be used to determine a subset of queues associated with a subset of radiologists. The subset of queues may be prioritized based on certain requirements, such as how many medical imaging reports a particular radiologist is required to review, how many medical imaging reports are required to be allocated to a particular radiologist, and the like. The highest prioritized queue may be selected and the medical imaging order may be transmitted to the radiologist associated with that queue.

Diagnostic systems and methods for measuring and assessing spine instability are described which involve reconstruction of a dynamic three-dimensional model of a patient's spine moving through a range of motions, and optimization of the three-dimensional model to provide relative three-dimensional position and orientation data for each vertebra in the spine throughout the motion. Vertebral movement is thereby accurately measured and instability determined for presentation in a user-friendly form.

A method for generating a combined contrast medium and blood vessel representation of contrast-enhanced image data of breast tissue to be examined includes capturing first and second contrast-medium-influenced x-ray projection measurement data of the breast tissue with respective differing first and second x-ray energies. First and second image data sets are reconstructed based respectively on the first and second measurement data. A dual-energy image data set is ascertained based on the first and the second image data sets. A blood vessel image is ascertained based on at least one image data set. A blood vessel image is represented together with the dual-energy image data set in a combined contrast medium and blood vessel representation. An image data generating system is also provided.

A radiation tomographic imaging apparatus is characterized in comprising: a first reconstructing section for reconstructing a plurality of temporally different first radiation tomographic images for a required slice position; an information-on-movement acquiring section for acquiring information on movement of a body part in a subject based on the plurality of first radiation tomographic images; an information creating section for creating a motion profile MP indicating a temporal change of the information on movement; an identifying section for identifying a time Ts when motion of the body part in the subject stops based on the motion profile MP; and a second reconstructing section for reconstructing a second radiation tomographic image for the subject at the time Ts.

A super-resolution digital tomosynthesis system for imaging an object including a source configured to emit penetrating particles toward an object; a detector configured to acquire a series of projection images of the object in response to the penetrating particles from the source; positioning apparatus configured to position the source and the detector; and an imaging system coupled to the source, the detector, and the positioning apparatus. The imaging system is configured to control the positioning apparatus to position the source in relation to the detector along a scan path and to change a distance between the source and the detector, control the source and the detector to acquire the series of projection images along the scan path with the distance change between the source and detector, and construct a tomographic volume exhibiting super-resolution from data representing the acquired series of projection images.
