Epub 2018 Oct 19., doi: 10.1002/mp.13202., 2018.10, Purpose : To identify the optimal mother wavelets in survival prediction of lung cancer patients using wavelet-decomposition-based (WDB) radiomic features in CT images.
Materials and Methods: CT images of patients with histologically confirmed non-small cell lung carcinomas (NSCLCs) in Training (Dataset T; n = 162) and validation (Dataset V; n = 143) datasets were analyzed for this study. The optimal mother wavelets were identified based on the impacts of the WDB radiomic features on the patient survival times. 432 three-dimensional WDB radiomic features were calculated from regions of interest (ROI) of 162 tumor contours. A Coxnet algorithm was used to select a subset of radiomic features (signature) based on the prediction of survival times with a 5-fold cross-validation. The impacts of the radiomic features on the patients’ survival times were assessed by using a multivariate Cox proportional hazard regression (MCPHR) model. The major contribution of this study was to identify optimal mother wavelets based on a maximization of a novel ranking index (RI) incorporating the Coxnet prediction error and the summation of the p-values of the radiomic features in the MCPHR model on Dataset T. The prognostic performance of the optimal mother wavelets was validated based on the concordance index (CI) of the MCPHR models when applied to Dataset V. The proposed approach was tested by using 31 mother wavelets from 6 wavelet families that were available in a commercially available software (Matlab® 2016b).
Results: The optimal mother wavelets were Symlet 5 and Biorthogonal 2.6 at 128 re-quantization levels, which yielded RIs of 4.27±0.29 (3 features) and 6.50±0.50 (5 features), respectively. The CIs of the MCPHR models of Symlet 5 were 0.66±0.03 (Dataset T) and 0.64±0.00 (Dataset V), whereas those of Biorthogonal 2.6 were 0.68±0.03 (Dataset T) and 0.62±0.02 (Dataset V). The radiomic signatures included the GLRLM-based HLH gray level non-uniformity feature that demonstrated statistically significant differences in stratifying patients with better and worse prognoses in Datasets T and V.
Conclusion: This study has revealed the potential of Symlet and Biorthogonal mother wavelets in the survival prediction of lung cancer patients by using WDB radiomic features in CT images..

We based our study on the assumption that interfractional target shape variations are not negligible as another source of uncertainty for the determination of precise CTV-to-PTV margins. Thus, we investigated the interfractional shape variations of CTVs based on a point distribution model (PDM) for prostate cancer radiation therapy.
Materials and Methods: To quantify the shape variations of CTVs, the PDM was applied for the contours of 4 types of CTV regions (low-risk, intermediate- risk, high-risk CTVs, and prostate plus entire seminal vesicles), which were delineated by considering prostate cancer risk groups on planning computed tomography (CT) and cone beam CT (CBCT) images of 73 fractions of 10 patients. The standard deviations (SDs) of the interfractional random errors for shape variations were obtained from covariance matrices based on the PDMs, which were generated from vertices of triangulated CTV surfaces. The correspondences between CTV surface vertices were determined based on a thin plate spline robust point matching algorithm. The systematic error for shape variations was defined as the average deviation between surfaces of an average CTV and planning CTVs, and the random error as the average deviation of CTV surface vertices for fractions from an average CTV surface.
Results: The means of the SDs of the systematic errors for the 4 types of CTVs ranged from 1.0 to 2.0 mm along the anterior direction, 1.2 to 2.6 mm along the posterior direction, 1.0 to 2.5 mm along the superior direction, 0.9 to 1.9 mm along the inferior direction, 0.9 to 2.6 mm along the right direction, and 1.0 to 3.0 mm along the left direction. Concerning the random errors, the means of the SDs ranged from 0.9 to 1.2 mm along the anterior direction, 1.0 to 1.4 mm along the posterior direction, 0.9 to 1.3 mm along the superior direction, 0.8 to 1.0 mm along the inferior direction, 0.8 to 0.9 mm along the right direction, and 0.8 to 1.0 mm along the left direction.
Conclusions: Since the shape variations were not negligible for intermediate and high risk CTVs, they should be taken into account for the determination of the CTV-to-PTV margins in radiation treatment planning of prostate cancer..

AI approaches are the computational algorithms or systems that can accurately perform high inference based on a huge number of knowledge data. At around the same time as the third large wave of AI, an idea of radiomics has come out from radiation oncology as one of feasible approaches for solving the issues in precision medicine and practically performing it based on multimodality medical images in a non-invasive, fast, and low-cost way. Radiomics is a field based on data science that massively and comprehensively analyzes a huge amount of the medical images to extract a large number of phenotypic features reflecting disease traits, and to discover signatures (radiomic biomarkers) that can predict patients’ prognoses. Machine learning algorithms of AI are boosting radiomics powers for prediction or estimation of what are associated with treatment strategies such as survival time, recurrence, adverse events, and subtypes. Since a number of machine learning software are open-sourced and easy-to-use for radiation oncology staffs, this third boom of AI could be a practical phase of AI in radiation oncology. Radiomics with AI are considered “specialized AI”, which may potentially provide one of practical ways for precision medicine in radiation therapy by emphasizing outcomes and reducing toxicity for individual patients..
25. Hidetaka Arimura, Data-Science-Based Radiomics (Radiomics & Artificial Intelligence Workshop, 11-Nov-2018), 18th Asia-Oceania Congress of Medical Physics and 16th South-East Asia Congress of Medical Physics (AOCMP, Kuala Lumpur), 2018.11, Medicine including cancer treatment is moving toward “precision medicine,” in which health care is personalized on a basis of patients’ data (e.g. genes and health care records) to take into account individual variability (patient or tumor heterogeneity). However, there are several issues in the precision medicine of the cancer treatment such as invasive biopsy and slow throughput for examination of gene mutations from sampled specimens. Besides, since tumors are heterogeneous, a small part of a tumor obtained by a single biopsy could be unreliable for the precision medicine. Consequently, it could not be reasonable to practically perform the precision medicine of the cancer treatment. Therefore, the idea of radiomics has come out from radiation therapy for solving the issues and performing the “practical” precision medicine. Radiomics is a field based on data science that massively and comprehensively analyzes a huge amount of the medical images to extract a large number of phenotypic features reflecting disease traits, and to discover signatures that can predict patients’ prognoses. The signatures are considered imaging biomarkers, and they are defined as vectors capsulating significant selected features as vector elements. Data science is an interdisciplinary field among statistics, pattern recognition, machine learning, data mining, data processing, data visualization, etc., to inductively discover features or hidden meaningful patterns of natural, human, and social phenomena with the vast amount of multidimensional data using computer science and domain knowledge. The purpose of data science is “learning from data” by extracting important patterns and trends, and understand “what the data says”. Since the speaker believes that the data science is the key to the success of the radiomics for statistically delving into the ‘dark’ big medical data including the huge amounts of medical images, he will describe the basics of radiomics and data science..

The cerebral cortical thickness was three-dimensionally measured on each cortical surface voxel by using a localized gradient vector trajectory in a fuzzy membership map. The proposed method could be useful for the 3D measurement of the cerebral cortical thickness on individual cortical surface voxels as an atrophy feature in AD..

First, the PET images were registered with the treatment planning CT images through the diagnostic CT images of PET/CT. Second, six voxel-based features including voxel values and magnitudes of image gradient vectors were derived from each voxel in the planning CT and PET /CT image data sets. Finally, lung tumors were extracted by using a support vector machine (SVM), which learned 6 voxel-based features inside and outside each true tumor region determined by radiation oncologists. The results showed that the average DSCs for 3 and 6 features for three cases were 0.744 and 0.899, and thus the SVM may need 6 features to learn the distinguishable characteristics. The proposed method may be useful for assisting treatment planners in delineation of the tumor region..
