Compared to IPSA, it is an inverse optimization method which takes into account current clinical experience gained from manual treatment planning. The Paddick index for the volume of two times prescribed dose was outstandingly low.Ĭonclusions : HIPO can produce clinically acceptable treatment plans with the elimination of high dose regions in normal tissue. This resulted in high dose regions located in the normal tissue. IPSA was able to achieve acceptable dosimetric results. The values of both conformity indices were the lowest. It reduced the loading time of needles and the overall treatment time. Results : HIPO was able to achieve a similar dose distribution to manual planning with the restriction of high dose regions. Al sufrir alteraciones por una ingestin masiva o por sorber rpido (y tragar aire) tambin se puede producir el hipo. Dosimetric parameters, absolute volumes of normal tissue receiving reference doses, absolute loading times of tandem, ring and interstitial needles, Paddick and COIN conformity indices were evaluated. Material and methods : For 20 patients, manually optimized, and, inversely optimized treatment plans with Hybrid Inverse treatment Planning and Optimization (HIPO) and with Inverse Planning Simulated Annealing (IPSA) were created. Éste se contrae de forma súbita en medio de una. El hipo es un movimiento involuntario del diafragma, el músculo que empleamos para respirar. Purpose : The purpose of this study was to compare two inverse planning algorithms for cervical cancer brachytherapy and a conventional manual treatment planning according to the MUW (Medical University of Vienna) protocol. La explicación es más sencilla de lo que parece.
