Treating tumors that are subject to intrafractional motion (e.g. lung tumors) with scanned particle beams leads to deterioration of the deposited dose distributions. One possible technique to mitigate motion effects is beam tracking [1]. In case of rotational motion the beam path and thereby the dose deposition in the plateau region proximal of the Bragg peak position changes despite adaptation...
conclusions: these results indicate preventive effects of all natural adjuvants (especially g2) on pathological changes of the lung in sensitized guinea pigs. results: all pathological changes in s group including the eosinophil infiltration (scoring 3.28 ± 0.28), lymphocyte infiltration (2.82 ± 0.26), local epithelial necrosis (2.71 ± 0.47) and mucosal plug (2.75 ± 0.37) were significantly hig...
This paper presents a new approach for lung registration and cardiac motion prediction, based on a 3D geometric model of the left lung. Feature points, describing a shape of this anatomical object, are automatically extracted from acquired tomographic images. The "goodness-of-fit" measure is assessed at each step in the iterative scheme until spatial alignment between the model and subject's sp...
