Abstract
An apparatus includes: a processor configured for obtaining a first image that corresponds with a first multi-leaf collimator (MLC) configuration, wherein the first image is generated when the MLC is stationary, obtaining a second image that corresponds with a second MLC configuration, wherein the second image is generated when the MLC and/or another component of a radiation machine is being operated to track a motion, and performing an analysis based at least in part on the first image and the second image to obtain a result; and a non-transitory medium for storing the result.
Claims30
A method comprising:
- obtaining a first image that corresponds with a first multi-leaf collimator (MLC) configuration, wherein the first image is generated when the MLC is stationary;
- obtaining a second image that corresponds with a second MLC configuration, wherein the second image is generated when the MLC and/or another component of a radiation machine is being operated to track a motion;
- performing an analysis based at least in part on the first image and the second image using a processor to obtain a result;
- and
- storing the result in a non-transitory medium.
An apparatus comprising:
- a processor configured for
- obtaining a first image that corresponds with a first multi-leaf collimator (MLC) configuration, wherein the first image is generated when the MLC is stationary,
- obtaining a second image that corresponds with a second MLC configuration, wherein the second image is generated when the MLC and/or another component of a radiation machine is being operated to track a motion, and
- performing an analysis based at least in part on the first image and the second image to obtain a result;
- and
- a non-transitory medium for storing the result.
A product having a non-transitory medium storing a set of instructions, an execution of which by a processor causes a method to be performed, the method comprising:
- obtaining a first image that corresponds with a first multi-leaf collimator (MLC) configuration, wherein the first image is generated when the MLC is stationary;
- obtaining a second image that corresponds with a second MLC configuration, wherein the second image is generated when the MLC and/or another component of a radiation machine is being operated to track a motion;
- performing an analysis based at least in part on the first image and the second image to obtain a result;
- and
- storing the result.
A method comprising:
- obtaining a first set of images that are created while a multi-leaf collimator (MLC) is in different respective static configurations;
- obtaining an input image that is created while the MLC is being operated to track a motion;
- selecting one or more images from the first set of images that correspond with the input image;
- performing an analysis based at least in part on the selected one or more images and the input image using a processor to obtain a result;
- and
- storing the result in a non-transitory medium.
