  • 摘要:Accurate image registration for CTCT, CTMRI for brain is necessary to obtain clinical information from diagnostic images and translate the information to radiotherapy treatment planning CT images. Mostly in cases of PostSurgery cases that have been operated outside hospitals and are being referred for PostOperative adjuvant Radiotherapy to our Centre, where the preoperative volume is very importantly necessary in radiotherapy planning, a pre preparation was needed. The intention of the work is two folds. One is to make the outside clinic diagnostic images with rectangular matrix dimension compatible with our treatment planning system (TPS), Eclipse version 11. Second use point by point registration in three orthogonal planes as prepreparation process for specific outside clinic diagnostic images where registration accuracy was not the intention. Both the intentions were handled using inhouse developed software in Matlab and the saved registered images were transferred to TPS for auto matching the images for fine tune. Visual inspection of the registration was in good agreement. The mean variation for the dimension of the registered phantom images from the Base image of the phantom were found to be 0.5 mm which was less than 1 pixel value.
