“…Standardna 3D konformalna radioterapija (3D-CRT) sprovodi se kombinacijom seta stacionarnih zračnih snopova koji se prilagođavaju obliku ciljnog volumena primenom MLC-a. Zračni snopovi imaju uniforman intenzitet na nivou celog zračnog polja, a mogu se modifikovati korišćenjem kompenzatornih filtera, čime se u zračnom volumenu postiže homogena distribucija zračne doze (9).…”

“…Proces IMRT podrazumeva da se nakon adekvatne imobilizacije pacijenta načini CT skeniranje regije od interesa, sa upotrebom kontrasta koji je naročito važan zbog identifikacije krvnih sudova u čijoj neposrednoj blizini se nalaze limfni nodusi koji su ciljna meta u zračnom polju. Potom se vrši delineacija ciljnih volumena i organa od rizika (9). Postoji mogućnost delineacije više ciljnih volumena koji mogu biti različito tretirani (različite ukupne doze, dnevno frakcionisanje) metodom simultanog integrisanog boost-a (SIB), što je naročito važno u okviru lečenja metastatski izmenjenih limfatika sa većim dozama (15).…”

Introduction: Postoperative radiotherapy in patients with cervical cancer significantly reduces the risk of loco-regional disease relapse, but at the same time is associated with increased toxicity at surrounding healthy organs and tissues. The occurrence of toxicity can significantly reduce the patient's quality of life, despite the complete remission of the disease. Aim: In this review article, we present modern radiotherapy technique-intensity modulated radiotherapy (IMRT), its advantages and disadvantages. Significant number of studies documented the results of postoperative IMRT role in treatment of cervical cancer, in reducing acute and late toxicity. Conclusions: Compared to previously used modalities of irradiation, IMRT is a complex radiotherapy technique-technically and time-consuming-which achieves escalation of the dose in the target volume, with better organ risk management, while decrease the frequency of acute and chronic complications and improve the quality of life after treatment. Of particular importance is the IMRT in postoperative approach in patients with a good prognosis.

“…Several respiration-induced motion management techniques have been proposed to characterize the tumor motion. Of particular interest is the four-dimensional computed tomography (4D CT) technique, which is commonly deployed to characterize the respiration-induced movement of internal organs and improve the quality of 3D CT images and tumor localization accuracy [11]. The generation of 4D CT images requires a CT simulator and a medical external surrogate device.…”

This paper proposes a time-series deep-learning 3D Kinect camera scheme to classify the respiratory phases with a lung tumor and predict the lung tumor displacement. Specifically, the proposed scheme is driven by two time-series deep-learning algorithmic models: the respiratory-phase classification model and the regression-based prediction model. To assess the performance of the proposed scheme, the classification and prediction models were tested with four categories of datasets: patient-based datasets with regular and irregular breathing patterns; and pseudopatient-based datasets with regular and irregular breathing patterns. In this study, ‘pseudopatients’ refer to a dynamic thorax phantom with a lung tumor programmed with varying breathing patterns and breaths per minute. The total accuracy of the respiratory-phase classification model was 100%, 100%, 100%, and 92.44% for the four dataset categories, with a corresponding mean squared error (MSE), mean absolute error (MAE), and coefficient of determination (R2) of 1.2–1.6%, 0.65–0.8%, and 0.97–0.98, respectively. The results demonstrate that the time-series deep-learning classification and regression-based prediction models can classify the respiratory phases and predict the lung tumor displacement with high accuracy. Essentially, the novelty of this research lies in the use of a low-cost 3D Kinect camera with time-series deep-learning algorithms in the medical field to efficiently classify the respiratory phase and predict the lung tumor displacement.
