China has established and implemented marine ecological conservation red line (MECRL) system to strengthen the bottom constraints ensure security. This paper introduces concept of MECRL process overall consideration national delineation, which is defined “spatial-division + differential control measures”. The in Bohai Sea pilot delineation nationwide are introduced. At present, accounts for abo...

Efficient forest management demands detailed, timely information. As high spatial resolution remotely sensed imagery becomes more available, there is a great potential for conducting high accuracy forest inventory and analysis automatically and cost-efficiently. Recent research aimed at providing tree-based forest inventory measurements has generated numerous algorithms for automatic individual...

Automated atlas-based segmentation (ABS) algorithms present the potential to reduce the variability in volume delineation. Several vendors offer software that are mainly used for cranial, head and neck, and prostate cases. The present study will compare the contours produced by a radiation oncologist to the contours computed by different automated ABS algorithms for prostate bed cases, includin...

A cloud is a triple consisting of a fuzzy object model, a delineation algorithm, and a criterion function for evaluating delineations. It employs recognition and delineation in a tightly coupled manner to accomplish image segmentation. It captures shape variations of a given object/object assembly to form an uncertainty region for its boundary. For any image position, delineation is executed in...

The purpose of the Oncology Nursing Society (ONS) Oncology Nurse Navigator Role Delineation Study was to examine the job-function activities of the oncology nurse navigator, thus providing an understanding of this unique role. The Role Delineation Advisory Committee consisting mainly of oncology nurse navigators was formed to provide content expertise to Applied Measurement Professionals, which...

In the thorax, the extent of tumor may be more accurately defined with the addition of (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) to computed tomography (CT). This led to the increased utility of FDG-PET or PET/CT in the treatment planning of radiotherapy for non-small cell lung cancer (NSCLC). The inclusion of FDG-PET information in target volume delineation not only imp...

The aim of automated electrocardiogram (ECG) delineation system is the reliable detection of fundamental ECG components and from these fundamental measurements, the parameters of diagnostic significance, namely, P-duration, PR-interval, QRS-duration, QTinterval, are to be identified and extracted. In this work, two supervised machine learning algorithms, K-Nearest neighbour (KNN) and Support Ve...

Radiation oncology is a medical discipline mainly involved in the treatment of cancer with ionizing radiation. It is based on full knowledge of individual patient cancer disease, delineation of the target volume including tumor that has to receive therapeutic radiation dose, delineation of normal tissues to be spared, treatment planning with dedicated calculation algorithms, radiation delivery ...

Positron emission tomography can be used in radiation oncology for the delineation of target volumes in the treatment planning stage. Numerous publications deal with this topic and the scientific community has investigated many methodologies, ranging from simple uptake thresholding to very elaborate probabilistic models. Nevertheless, no consensus seems to emerge. This paper reviews delineation...

The improved accuracy in tumor identification with FDG-PET has led to its increased utilization in target volume delineation for radiotherapy treatment planning in the treatment of lung cancer. However, PET/CT has constantly been influenced by respiratory motion-related image degradation, which is especially prominent for small lung tumors in the peri-diaphragmatic regions of the thorax. Here, ...
