Background: Radiomics can quantify tumor phenotypic characteristics non-invasively by applying feature algorithms to medical imaging data. In this study, we investigated the association between radiomics features and the tumor histological subtypes, and we aimed to establish a nomogram for the classification of small cell lung cancer (SCLC) and non...

Objectives Chondrosarcomas are malignant bone tumors considered as resistant to radiotherapy. To unravel mechanisms of resistance, we compared biological responses of several chondrosarcomas to X-ray irradiations in normoxia and hypoxia. Since hadrontherapy with Carbon-ions gave interesting clinical outcomes, we also investigated this treatment in ...

To develop and validate a computed tomography (CT)-based radiomics nomogram for predicting human epidermal growth factor receptor 2 (HER2) status in patients with gastric cancer. This retrospective study included 134 patients with gastric cancer (HER2-negative: n=87; HER2-positive: n=47) from April 2013 to March 2018, who were then randomly divided...

Dosimetric assessment following permanent prostate brachytherapy (PPB) commonly involves seed localization using CT and prostate delineation using coregistered MRI. However, pelvic CT leads to additional imaging dose and requires significant resources to acquire and process both CT and MRI. In this study, we propose an automatic postimplant dosimet...

The titanium nitride (TiN) has mechanical properties that are useful in a wide range of applications. In special, it is being investigated to improve the surfaces of bone implants. The mechanical properties of TiN films deposited by reactive magnetron sputtering and their correlations with microstructure will be investigated in this dissertation as...

An instrument to measure the intensity (energy fluence rate) of photons in the mammography range (22 to 33 kVp) and the tube voltage of a mammograph. The instrument consists of a chamber with a pyroelectric sensor of lead methaniobate (PbNb2O6) and its signal conditioning circuit. Polyacid was used to make the pyroelectric chamber in a 3D printer. ...
