Method and device for comparing radiographic images |
| 摘要 |
The present disclosure provides a method of standardizing a digital radiographic medical image, including obtaining a digital radiographic image of a variable attenuation plate to provide at least one reference value of at least one image characteristic, such as optical density and contrast, and standardizing the digital radiographic medical image against the reference values. Also provided are methods for comparing two or more radiographic images including standardizing the images against at least one reference value of at least one image characteristic obtained from a digital radiographic image of a variable attenuation plate. |

1. A method of comparing a first radiographic medical image with a second radiographic medical image, comprising:
recording a first radiographic medical image of a patient including a first image of a variable attenuation plate; recording a second radiographic medical image of the patient including a second image of the variable attenuation plate; determining optical density and contrast reference values from the first and second images of the variable attenuation plate; and standardizing the first radiographic medical image and the second radiographic medical image against the optical density and contrast reference values such that the first radiographic medical image can be compared to the second radiographic medical image. |
