Abstract
Methods and apparatus for determining radiation doses based on phantom matching are disclosed. An example apparatus includes an image processor to process a scout image to determine the first dimensions of an anatomical landmark of the scout image file; a comparator to select a phantom model based on the first dimensions, the phantom model including the anatomical landmark with second dimensions substantially similar to the first dimensions; and a dose calculator to calculate a radiation dose for an organ in the anatomical landmark based on the selected phantom.
Claims20
An apparatus comprising:
- an image processor configured to process a first scout image to determine a first set of dimensions of a first anatomical landmark of a first scout image file;
- a flag generator configured to flag the first scout image when at least one of (A) the first anatomical landmark in the first scout image does not include an organ (B) the image processor cannot determine the first set of dimensions of the first anatomic landmark, or (C) the first set of dimensions are outside of a predefined range, the flag to prompt a capture of a second scout image;
- the image processor further configured to process the second scout image to determine a second set of dimensions of a second anatomical landmark of a second scout image file;
- a comparator configured to select a phantom model based on the second set of dimensions, the phantom model including the second anatomical landmark with a third set of dimensions that match the second set of dimensions;
- and
- a dose calculator configured to calculate a radiation dose for an organ in the second anatomical landmark based on the selected phantom.
A method comprising:
- processing a first scout image to determine a first set of dimensions of a first anatomical landmark of a first scout image file;
- flagging the first scout image when at least one of (A) the first anatomical landmark in the first scout image does not include an organ (B) the first set of dimensions of the first anatomic landmark cannot be determined, or (C) the first set of dimensions are outside of a predefined range, the flag to prompt a capture of a second scout image;
- processing the second scout image to determine a second set of dimensions of a second anatomical landmark of a second scout image file;
- selecting a phantom model based on the second set of dimensions, the phantom model including the second anatomical landmark with a third set of dimensions that match the set of second dimensions;
- and
- calculating a radiation dose for an organ in the second anatomical landmark based on the selected phantom.
A tangible computer readable storage medium comprising instructions which, when executed, cause a machine to at least:
- process a first scout image to determine a first set of dimensions of a first anatomical landmark of a first scout image file;
- flag the first scout image when at least one of (A) the first anatomical landmark in the first scout image does not include an organ (B) the first set of dimensions of the first anatomic landmark cannot be determined, or (C) the first set of dimensions are outside of a predefined range, the flag to prompt a capture of a second scout image;
- process the second scout image to determine a second set of dimensions of a second anatomical landmark of a second scout image file;
- select a phantom model based on the second set of dimensions, the phantom model including the second anatomical landmark with a third set of dimensions that match the second set of dimensions;
- and
- calculate a radiation dose for an organ in the second anatomical landmark based on the selected phantom.
