Disclosed herein is a method of acquiring a medical image of an X-ray apparatus, including: acquiring an original radiation image of a target object and capturing condition information of the object; acquiring a scatter radiation image related to the original radiation image by inputting the original radiation image and the capturing condition information to a learning network model configured to estimate scatter radiation; and acquiring a scatter radiation-processed medical image from the original radiation image on the basis of the original radiation image and the scatter radiation image, wherein the learning network model configured to estimate scatter radiation is a learning network model taught using a plurality of scatter radiation images and a plurality of pieces of capturing condition information related to each of the plurality of scatter radiation images.

A method includes forming a test key. The formation of the test key includes forming a first plurality of semiconductor strips, and cutting the first plurality of semiconductor strips into an array of a second plurality semiconductor strips, with each row of the array being formed from one strip in the first plurality of semiconductor strips, forming isolation regions in recesses between the second plurality of semiconductor strips, and recessing the isolation regions. The top portions of the second plurality of semiconductor strips protrude higher than the isolation regions form semiconductor fins, which form a fin array. An X-ray beam is projected on the test key. A diffraction pattern is obtained from scattered X-ray beam scattered from the test key.

An anti-scatter grid for an X-ray beam detector is provided. The anti-scatter grid includes a plurality of X-ray absorption plates and a carrier body to which the plurality of X-ray absorption plates are fastened. The carrier body is embodied in a meander shape with a plurality of linearly extending subsections and curve sections connecting the plurality of linearly extending subsection with one another. At least one X-ray absorption plate is arranged in each linearly extending subsection of the plurality of linearly extending subsections.

A method of determining the imaging arm's optimal 3-dimensional position and orientation for taking images of a body implant or body structure such as vertebral body is provided. Test images of vertebral body of interest are initially taken by the user and are received by the imaging device. The test images typically include AP and lateral x-ray images of the vertebral body. From the test images, the vertebral body is segmented. A 3-dimensional model of the vertebral body is then aligned against the corresponding vertebral body in the test images. Based on the alignment, a 3-dimensional position and orientation of the imaging arm for taking optimal A-P and lateral x-ray images are determined based on the aligned 3-dimensional model. The present method eliminates the need to repeatedly take fluoro shots manually to find the optimum images to thereby reduce procedural time, x-ray exposure and procedure costs.

Methods and systems are provided for calibrating a nuclear medicine imaging system having more than 5 detector heads. In one embodiment, a method includes obtaining residual center of gravity determinations corresponding to each of a plurality of detector units based on point source projections acquired over a series of detector unit rotational steps, obtaining center of gravity determinations for each of the plurality of detector units based on point source projections acquired over a series of detector unit sweep angles, obtaining a fit of the center of gravity determinations for each of the plurality of detector units, and determining a sweep offset for each of the plurality of detector units based on the residual center of gravity determinations and the fit of the center of gravity determinations for each of the plurality of detector units. In this way, a sweep axis zero degree position for each of the plurality of detector units is determined.

A method of determining a biophysical model for a lung of a patient from multiple x-ray measurements corresponding to different breathing phases of the lung is provided. The method includes extracting multiple displacement fields of lung tissue from the multiple x-ray measurements corresponding to different breathing phases of the lung. Each displacement field represents movement of the lung tissue from a first breathing phase to a second breathing phase and each breathing phase has a corresponding set of biometric parameters. The method includes calculating one or more biophysical parameters of a biophysical model of the lung using the multiple displacement fields of the lung tissue between different breathing phases of the lung and the corresponding sets of biometric parameters.
