Abstract
A method for adjusting a radiation dose during imaging of an object within a subject is provided. The method includes identifying a task in a first frame that contains the object, the first frame generated via exposing the subject to a radiation beam; and adjusting the radiation beam based at least in part on the task prior to generating a second frame that contains the object, the second frame generated via exposing the subject to the radiation beam.
Claims21
A method for adjusting a radiation dose during imaging of an object within a subject, the method comprising:
- identifying a task in a first frame that contains the object, the first frame generated via exposing the subject to a radiation beam;
- and
- adjusting the radiation beam based at least in part on the task prior to generating a second frame that contains the object, the second frame generated via exposing the subject to the radiation beam.
A method for adjusting a radiation dose during imaging of an object within a subject, the method comprising:
- generating a first frame that contains the object via applying a mask to a first image obtained via exposing the subject to a radiation beam;
- identifying a task in the first frame;
- generating a second frame that contains the object via applying the mask to a second image obtained via exposing the subject to the radiation beam;
- comparing the first frame with the second frame to obtain a contrast indicator;
- adjusting the mask based at least in part on the contrast indicator;
- and
- adjusting the radiation beam based at least in part on at least one of the task and the adjusted mask.
An imaging system that adjusts a radiation dose during imaging of an object within a subject, the imaging system comprising:
- a controller configured to generate a first frame that contains the object via exposing the subject to a radiation beam;
- and
- wherein the controller is further configured to identify a task in the first frame and adjust the radiation beam based at least in part on the identified task prior to generating a second frame that contains the object via exposing the subject to the radiation beam.
A method for adjusting a radiation dose during imaging of an object within a subject, the method comprising:
- acquiring a first series of images in rotation around the subject prior to injection of a contrast agent;
- acquiring a second series of images in rotation around the subject after injection of the contract agent;
- and
- wherein a pattern is identified in a first image of the second series of images, and subsequent images of the second series of images acquired after the first image are optimized based at least in part on the identified pattern.
