An apparatus including an x-ray source and detector where the source is disposed behind the detector and the detector is configured with a hole through which an x-ray beam emitted by the source can be transmitted to target tissue is provided. During operation, the source emits an x-ray beam through the hole in the detector. The x-ray beam may then be incident on an area of a subject to be imaged and cause various reflections and/or absorptions. The detector can detect signals reflected by the subject and an x-ray image can be generated accordingly.

An x-ray apparatus and method can improve x-ray imaging in a variety of ways. For example, the improve x-ray apparatus can reduce scatter from x-ray images acquired by two-dimensional detectors. An improved 2D x-ray apparatus can provide 3D imaging for medical and/or industrial applications. An improved 2D x-ray apparatus and method can produce separate material imaging, and composition analysis for characterization and correlation of image, densitometry, and composition information of individual component or individual material within a single subject. Non-rotational 3D microscopy, combining 2D or 3D full field x-ray imaging and high resolution 2D or 3D x-ray microscopy or spectral absorptiometry and spectroscopy can achieve a higher resolution and wider field of view in x-ray imaging and quantitative analysis in 3D and real time. The x-ray apparatus can improve tracking and/or surgical guidance in time and/or space.

An on-board proton imaging system may include a continuous rotation gantry configured to generate proton beams during rotation thereof to penetrate a patient object, a beam detector arranged opposite of the gantry around the object and configured to receive residual proton beams having passed through the object, and a controller in communication with the gantry and a multilayer detector. The controller may be configured to instruct the gantry to generate the proton beams based on patient factors, receive data from the detector indicating at least an energy level of the residual beams, and generate a three-dimensional image based on the received data.

A computer-implemented system and method for generating a medical image is provided. In some embodiments, the medical image is generated by determining a location and an alignment for a first tracking detector with respect to a particle beam system. The direction of a beam generated from the particle beam system is determined. A first position of a first particle from a detected particle hit on the first tracking detector is also determined. A determination is made as to a first residual range of the first particle from a detected particle hit on a residual range detector. The system reconstructs a path for the first particle based on the location, the alignment, the first position, and the first residual range of the first particle. The resulting medical image that is generated by the system is based on the reconstructed path for the first particle.

The present disclosure relates to an x-ray imaging method using a variable imaging plane projection and to an x-ray imaging device applying the same. By applying a variable imaging plane projection using at least two sets of scan data for different heights obtained while varying the height of the x-ray generator from an imaging object, it is possible to solve problems caused due to a magnification effect generated in the x-ray imaging field based on a fan-beam-type or cone-beam-type x-ray generator, thereby providing more accurate x-ray image information.

An imaging system utilizes 2D DXA images obtained in a tomographic imaging process or mode in order to provide more detailed information to the operator of the bone structure of the patient. The imaging system obtains multiple 2D DXA images at different angles with regard to the patient in a number of passes across the body of the patient. These 2D DXA images can then be utilized to reconstruct at least one 2D slice of the body of the patient, such as in a plane parallel to the plane of a patient support surface, such as a scanner table. The information provided by the tomographic reconstruction provides enhancements to the process of modifying a 3D FEA model associated to an already available set of tomographic reconstructed slices selected from the comparison with the current tomographic reconstructed slices. In this manner, the system and method provide a significant reduction in the error of the resulting modified 3D FEA model for review and analysis compared to a 2D approach.

An apparatus to examine a target in a patient includes an x-ray source configured to deliver a first x-ray beam towards the target, a device having an array of openings, the device located at an angle less than 180 degrees relative to a beam path of the first x-ray beam to receive a second x-ray beam resulted from an interaction between the first x-ray beam and the target, and a detector aligned with the device, the detector located at an angle less than 180 degrees relative to the beam path of the first x-ray beam to receive a part of the second x-ray beam from the device that exits through the openings at the device.
