| Abstract: | According to the geometry deformation characteristic of scanned sequence image used in three dimensional computer radiotherapy treatment planning system,a sequence image normalizing method based on scanning image rulers has been developed.The method first models the image deformation caused by the tilted film as a projection model,and makes use of CT and MRI sequence image rulers,both vertical and horizontal,to rectify the deformation and calculate a few user defined marker's relative coordinates; then employs these markers to normalize the whole sequence image.The clinical result shows that the method is feasible and can satisfy the clinical image normalizing demand in three dimensional radiotherapy treatment planning system. |
