Methods and systems for pet imaging

#The present disclosure relates to the field of medical imaging, and in particular, to methods and systems for positron emission tomography (PET) imaging.

#Positron emission tomography (PET) is an important medical imaging way. A medical image refers to an image of internal tissues and organs of the object obtained by interacting with a human body or an experimental object in a non-invasive way with the help of a medium. The medical image may assist a doctor in the diagnosis and treatment of diseases, and the quality of the medical image has an important impact on assisting the doctor in diagnosing patients' conditions.

#Therefore, it is desirable to provide methods and systems for PET imaging to obtain a high-quality PET image.

#The present disclosure is further illustrated in terms of exemplary embodiments. These exemplary embodiments are described in detail with reference to the drawings. These embodiments are non-limiting exemplary embodiments, in which the same reference numbers represent the same structures, wherein:

#FIG. 1 is a schematic diagram illustrating an exemplary positron emission tomography (PET) imaging system according to some embodiments of the present disclosure;

#FIG. 2 is a flowchart illustrating an exemplary process for PET imaging according to some embodiments of the present disclosure;

#In order to more clearly illustrate the technical solutions related to the embodiments of the present disclosure, a brief introduction of the drawings referred to the description of the embodiments is provided below. Obviously, drawings described below are only some examples or embodiments of the present disclosure. Those skilled in the art, without further creative efforts, may apply the present disclosure to other similar scenarios according to these drawings. Unless obviously obtained from the context or the context illustrates otherwise, the same numeral in the drawings refers to the same structure or operation.

#It should be understood that the “system,” “device,” “unit,” and/or “module” used herein are one method to distinguish different components, elements, parts, sections, or assemblies of different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

#As used in the disclosure and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise; the plural forms may be intended to include singular forms as well. In general, the terms “comprise,” “comprises,” and/or “comprising,” “include,” “includes,” and/or “including,” merely prompt to include steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive listing. The methods or devices may also include other steps or elements.
