The method may include obtaining training samples, the training samples including at least one sample first image generated based on a first tracer, at least one reference first image each of which corresponds to one of the at least one sample first image and has a higher image quality than the corresponding sample first image, at least one sample second image generated based on a second tracer different from the first tracer, and at least one reference second image each of which corresponds to one of the at least one sample second images and has a higher image quality than the corresponding sample second image; and generating a trained image processing model by training a preliminary model using the training samples.

Abstract

The present disclosure provides systems, devices, and methods for image registration. The methods include obtaining a first medical image and a second medical image of a target subject, the first medical image indicating blood vessels of the target subject, the second medical image indicating an interventional tool in the target subject; determining an initial registration relationship between the first medical image and the second medical image; determining, based on a first physiological feature of the target subject at an acquisition time of the second medical image, a first motion state of the blood vessels at the acquisition time; and determining a target registration relationship between the first medical image and the second medical image based on the initial registration relationship and the first motion state of the blood vessels.

Abstract

A generating method, a system, and a device of a scanning image, and a computer-readable storage medium are provided. The method includes: scanning different positions of a target object, respectively, by changing a passing region of an imaging beam emitted from a scanning imaging source, obtaining a plurality of scanning data of the target object, and obtaining a scanning image corresponding to the target object based on the plurality of scanning data of the target object.

• G21K 1/04 - Arrangements for handling particles or ionising radiation, e.g. focusing or moderating using diaphragms, collimators using variable diaphragms, shutters, choppers

Abstract

A reconstructing method and a reconstructing apparatus of a medical image, a computer device, and a storage medium are provided. The method includes: acquiring a signal data set obtained by performing signal detection on a detected object via a detector array, determining an effective detecting range of each detector in the detector array when a detecting scenario is a target scenario, and extracting target signal data of each detector within a respective effective detecting range from the signal data set, and reconstructing a medical detecting image of the detected object based on the target signal data. The detector array is configured to siege the detected object in three dimensions and detect a trace signal emitted by the detected object to obtain the signal data set.
