Abstract Lower Goru sand intervals of Early Cretaceous age are proven reservoirs in the Indus Platform area. The delineation reservoir geometries is utmost importance while searching for stratigraphic and combination traps clastic reservoirs. data ten wells two 2D seismic lines from northern part Basin incorporated this study. These Formation correlated a third-order sequence framework to under...

Background and purpose Delineation of organs at risk (OARs), such as the bladder, rectum sigmoid, plays an important role in delivery optimal absorbed dose to target owing steep gradient high-dose rate brachytherapy (HDR-BT). In this work, we propose a deep convolutional neural network-based approach for fast reproducible auto-contouring OARs HDR-BT. Materials methods Images 113 patients with l...

Radiotherapy is a treatment where radiation used to eliminate cancer cells. The delineation of organs-at-risk (OARs) vital step in radiotherapy planning avoid damage healthy organs. For nasopharyngeal cancer, more than 20 OARs are needed be precisely segmented advance. challenge this task lies complex anatomical structure, low-contrast organ contours, and the extremely imbalanced size between l...

Lymph node station (LNS) delineation from computed tomography (CT) scans is an indispensable step in radiation oncology workflow. High inter-user variabilities across oncologists and prohibitive laboring costs motivated the automated approach. Previous works exploit anatomical priors to infer LNS based on predefined ad-hoc margins. However, without voxel-level supervision, performance severely ...

The intra- and inter-observer variability in delineation of the parotids on the kilo-voltage computed tomography (kVCT) and mega-voltage computed tomography (MVCT) were examined to establish their impact on the dose calculation during adaptive head and neck helical tomotherapy (HT). Three observers delineated left and right parotids for ten randomly selected patients with oropharynx cancer trea...

The success of radiotherapy depends on the accurate delineation of the clinical target volume. The delineation of the lymph node regions has most impact, especially for tumors in the head and neck region. The purpose of this article was the development an atlas for the delineation of the clinical target volume for patients, who should receive radiotherapy for a tumor of the head and neck region...

Tree detection and tree crown delineation from Airborne LiDAR has been focusing mostly on utilizing the canopy height model (CHM). This paper presents a method for individual tree crown delineation based on densities of high points (DHP) from the high resolution Airborne LiDAR. The DHP method relies on the fact that the density of received laser pulses above a certain height is high at the cent...
