Statistical Analysis on Impact of Image Preprocessing of CT Texture Patterns and Its CT Radiomic Feature Stability: A Phantom Study.

Aim: To examine computed tomography (CT) radiomic feature stability on various texture patterns during pre-processing utilizing the Credence Cartridge Radiomics (CCR) phantom textures.

Materials And Methods: Imaging Biomarker Explorer (IBEX) expansion for the abbreviation IBEX extracted 51 radiomic features of 4 categories from 11 textures image regions of interest (ROI) of the phantom. 19 software pre-processing algorithms processed each CCR phantom ROI.

How Cancer Care Developed in India in 75 Years of Independence-Tamil Nadu Scenario.

Tamil Nadu has always been in the forefront in medical care. This is also true in the field of cancer care. The predecessor of present Bernard Institute of Radiology (BIR) the Government X-ray Institute Chennai, Premier Radiological Institute and Cancer Hospital, Chennai and CMC Vellore Radiation oncology unit were all started pre independence.

Analysing the possibility of utilizing CBCT radiomics as an independent modality: a phantom study.

Aim: To verify if computed tomography (CT) radiomics were reproducible by cone beam CT (CBCT) radiomics by using Catphan® 504.

Materials And Methods: Catphan® 504 was imaged   using the default IGRT OBI  CBCT   imaging protocols and CT scanner. Seven known density image regions of the phantom were segmented and image feature was extracted by Imaging Biomarker Explorer (IBEX) software.
