1. A method implemented on a computing apparatus including a processor and a storage device for determining a dose of modulation (DOM) profile, the method comprising:
obtaining, by a camera, a 3D image of an object containing a thickness of a 3D contour of the object;
obtaining a topogram image of the object, wherein the topogram image includes attenuation data of multiple organs or tissues of the object;
obtaining a DOM profile generation model, wherein the DOM profile generation model is a neural network model; and
generating a DOM profile by inputting the 3D image and the topogram image that includes the attenuation data of the object into the DOM profile generation model, wherein the DOM profile is determined based on the thickness of the 3D contour of the object and the multiple organs or tissues of the object, the DOM profile shows a radiation dose of radiation varies with a radiation angle during a scan of the object using the radiation, wherein the DOM profile shows a relationship between modulations of radiation doses and time during the scan, and the generating the DOM profile includes:
segmenting the topogram image into a plurality of regions;
determining a plurality of regional DOM profiles based on the DOM profile generation model, each of the regional DOM profiles corresponding to one of the plurality of regions; and
generating the DOM profile based on the plurality of regional DOM profiles.
