The present disclosure may disclose methods and systems for treating an object. The method may include imaging an object fixed on a positioning device using an imaging device. The method may include obtaining a plan image of the object. The method may include generating information of a region of interest (ROI) of the object based on the plan image of the object. The method may include generating a treatment plan based on the information of the ROI. The treatment plan may include a plan isocenter on the plan image. The method may further include treating a target portion of the object based on the treatment plan using a treatment device. The object may be fixed on the positioning device from a moment that the object is started to fixed on the positioning device to an end of the treatment of the target portion.

Methods and systems for treating an object

A method may include obtaining a first image associated with an image to be segmented, and performing an iteration process for obtaining a target image. The iteration process may include one or more iterations each of which includes: obtaining an image to be modified; obtaining one or more modifications performed on the image to be modified; generating a second image by inputting the image to be segmented, the image to be modified, and the one or more modifications into the image segmentation model; in response to determining that the second image satisfies the first condition, terminating the iteration process by determining the second image as the target image; or in response to determining that the second image does not satisfy the first condition, initiating a new iteration of the iteration process by determining the second image as the image to be modified.

Methods and systems for medical image segmentation

The present disclosure may provide a collimator assembly. The collimator assembly may include a multi-leaf collimator (MLC) situated in a first plane and at least one block situated in a second plane different from the first plane. The MLC may include at least one first group of leaves and at least one second group of leaves opposing each other and being moveable along a first direction. One of the at least one block may be located at a position corresponding to an end of the at least one first group of leaves. Projection of one of the at least one block along a second direction may partially overlap projection of the at least one first group of leaves along the second direction.

Collimator assembly and operating method thereof

An economizer and an air conditioning system. The economizer includes a housing with a refrigerant inlet for connecting to a first heat exchanger, a refrigerant outlet for connecting to a second heat exchanger, and a suction port for connecting to an intermediate stage of a compressor provided thereon; and a choke portion configured to protrude inwardly from an inner wall of the housing and arranged close to the suction port, such that refrigerant flowing to the suction port is at least partially obstructed. According to the technical solutions of the present application, the refrigerant flowing to the suction port can be at least partially obstructed. When the liquid droplets carried by the refrigerant are obstructed by the choke portion, the liquid droplets are adsorbed on the wall surface to form a liquid film, and the movement of the liquid film is obstructed by the choke portion.

Economizer and air conditioning system

The present disclosure relates to a cavity of a medical device. The cavity may include a bore and an accommodating cavity configured to provide an accommodating space for at least a portion of a couch in a radial direction of the bore. The accommodating cavity may be disposed on an inner wall of the bore and extend along an axial direction of the bore, and the accommodating cavity may be configured to form, with the bore, a connected space in which the at least a portion of the couch is allowed to move along an axial direction of the bore.

Systems and methods for adjusting a beam-limiting device, the beam-limiting device including a plurality of movable components for shaping a radiation beam. The methods may include for each of the plurality movable components, determining an initial location of the movable component; determining a target location of the movable component; and determining, based on the initial location and the target location, a moving route of the movable component. The methods may also include causing the plurality of movable components to move along their respective moving routes. During the movement of the plurality of movable components along their respective moving routes, the shape of an irradiation region of the radiation beam passing through the beam-limiting device may remain unchanged or substantially unchanged.

Systems and methods for adjusting beam-limiting devices

System and methods for generating synthetic data according to a plurality of options are provided. According to a first option, synthetic data is generated based on an indication of one or more target distributions. According to a second option, a one or more target distributions are determined based on a sample data set, and synthetic data is generated based on the determined target distribution(s). According to a third option, a temporary synthetic data set is generated based on an indication of one or more target distributions, matches between the temporary synthetic data set and a sample data set are then identified, and a synthetic data set is then generated based on the identified matches. A system may automatically determine which option to leverage based on whether a user provides a sample data set, one or more target distributions, or both.

Systems and methods for generating synthetic data

A method for positioning an object positioned on a table is provided. The method may include: obtaining a plan image, the plan image illustrating a virtual surface of the object; obtaining, by one or more capture devices, a 3-dimensional (3D) image, the 3D image including a set of elements corresponding to the object; obtaining a registration result by registering the plan image and the 3D image; determining whether the object needs to be moved based on the registration result; and in response to a determination that the object needs to be moved, causing the object to move according to the registration result.
