Evaluation of CorePlanTM treatment planning system for 6 and 15 MV photon irradiation
Introduction: Radiotherapy is an effective modality to treat esophageal carcinoma. Due to various inhomogenous tissues with a variety of physical and radiological properties which can cause uncertainty in accurate dose calculations in radiation therapy, accuracy of TPS is very important. The aim of this study was to quantify dose calculation accuracy of CoreplanTM TPS in an inh...
متن کاملUnicystic Ameloblastoma: Differential Diagnosis and Treatment Planning
Unicystic ameloblastoma is a tumor of odontogenic origin. It is not a rare neoplasm and most often the lesion is asympthomatic. However, large lesions may cause painless swelling of the jaws. Here we report a case of unicystic ameloblastoma with pain, swelling of the posterior jaws along with teeth mobility. Samples of incisional biopsy of the lesion and also interaoperative frozen section were...

and the destination points are in different maps. For instance, bus-stop T3 can be reached from C1 by highway line H2 (or H1) to C3 and then by bus trip R1: S 22 (C1H2) ∧ S 34 (C3H2) ∧ T 22 (C3R1) ∧ T 23 (T3R1). Additional types of connections can be defined to express situations involving routes from a station to another. In procedural terms the previous definitions reduce to a search for inte...
متن کاملValidation of treatment planning system using simulation PRIMO code.
Introduction: In radiation therapy, in order to double-check the dosimetric results of the main treatment planning system (TPS), a distinct TPS, with few capacitances in terms of contouring and a variety of dose calculation algorithms is used. This system has the capability to double check the planification and the accurate prediction of dose distribution in order to be ensured...
متن کاملInvestigation of physical penumbra definition in treatment planning
Background: Due to the small size of the beamlets in IMRT (intensity modulated radiotherapy), physical penumbra is one of the important dosimetric parameters and small changes in the penumbra have a notable impact on the results. The physical penumbra width is defined as the lateral distance between two specified isodose curves at a specified depth of phantom. In this study, after demonstrating...
