In order to optimize accuracy of the planned corrective osteotomy, extensive preoperative planning is indispensable.
Contrast agents can also improve target delineation but may influence the accuracy of treatment planning algorithms (Ramm et al. 2001).
The systematic integration of these approaches to form patient-specific clinical workflows has great potential to improve accuracy of treatment planning and delivery.
Proton computed tomography (pCT) is currently being developed as an imaging modality for improving the accuracy of treatment planning in proton therapy.
To verify the dosimetric characteristics of 131Cs source in the Collaborative Ocular Melanoma Study COMSS) eye plaque brachytherapy, to compare 131Cs with 125I in a sample implant, and to examine the accuracy of treatment planning system in dose calculation.
However, imaging distortion and superimposition compromise the accuracy of treatment planning with these techniques [ 10].
However, given these results, low accuracy of the planning software must also be considered as one of the causes of malalignment.
Numerical results illustrate the applicability and accuracy of the trajectory planning.
Cheung et al(2001) verified the accuracy of the dose planning system Leksell GammaPlan using EGS4 Monte Carlo code for standard collimator sizes (4, 8, 14 and 18 mm) and a Co-60 photon beam.
Participants identified two additional factors important to the successful implementation of care plans: issues related to access (enhancing provider knowledge of the existence of care plans and ensuring providers have timely access) and issues related to the currency and accuracy of care plans.
These previous studies have focused on the accuracy of preoperative plans compared to the final surgical tactic, or on the inter- and intra-observer reliability of preoperative plans.
