A method and apparatus for estimating a position distribution of radiation emission The method and apparatus include obtaining a time difference between radiations detected by a pair of detectors, and creating a probability distribution function (PDF) indicating the probability of where the radiations actually were or may have been emitted. The PDF may be created based on the time difference and timing resolutions of the pair of detectors.

Method and apparatus for estimating position distribution of radiation emission

Provided is a magnetic resonance imaging and positron emission tomography (MRI-PET) system. The MRI-PET system includes a PET unit and a radiofrequency (RF) coil disposed within a gradient coil assembly.

Magnetic resonance imaging and positron emission tomography system

Methods and apparatuses for generating a blur model of a detector, and methods and apparatus for generating a medical image are provided. A method of generating a blur model of a detector may involve: changing locations of linear gamma ray sources along at least one line and obtaining signals emitted from the linear gamma ray sources; obtaining a point spread function (PSF) with respect to at least one voxel included in the at least one line; and generating a blur model of the detector from the PSF.

Apparatus and method for generating medical image using linear gamma ray source

A method and an apparatus for generating images are provided. The method includes generating a first sinogram for a state of an object from among states of the object based on a motion of the object, and a second sinogram for the states, based on data obtained from the object, and determining a region of interest (ROI) of the object based on the first sinogram. The method further includes extracting, from the second sinogram, third sinograms corresponding to the ROI, and estimating motion information of the ROI based on the third sinograms. The method further includes correcting the data based on the motion information.

Method and apparatus for generating image

A method of generating a response from a scanner in an imaging apparatus, a method of generating a medical image, an apparatus configured to generate a response of a scanner, and an apparatus configured to generate a medical image are provided. The method of generating a response of a scanner includes: generating point spread functions (PSFs) for the amount of the acquired signal from a point source; and generating the response of the scanner for the amount of the signal acquired, based on the PSF.

Methods and apparatuses for generating a response of a scanner in an imaging apparatus and medical image using the same

An image correction method includes detecting signals emitted from a tracer introduced into a target; intermittently extracting some of the detected signals according to a code string in which different codes are arranged; generating an image of the target using the extracted signals; and correcting the generated image based on at least one characteristic of the generated image.
