| 2 | Visibility improvement and mass segmentation of mammogram images using quantile separated histogram equalisation with local contrast enhancement显示文摘In this work, the authors develop a working software-based approach named ‘linearly quantile separated histogram equalisation-grey relational analysis’ for mammogram image (MI). This approach improves overall contrast (local and global) of given MI and segments breast-region with a specific end goal to acquire better visual elucidation, examination, and grouping of mammogram masses to help radiologists in settling on more precise choices. The fundamental commitment of this work is to demonstrate that results of good quality of breast-region segmentation can be accomplished from basic breast-region segmentation if the input image has good contrast and a better interpretation of hidden details. They have evaluated the proposed strategy for MIAS-MIs. Experimental results have shown that the proposed approach works better than state-of-the-art. | Bhupendra Gupta Mayank Tiwari Subir Singh Lamba | 2019 | CAAI Transactions on Intelligence Technology2019，4，2： | 0 |
| 3 | Impact of COVID-19 pandemic on radiology education,training,and practice:A narrative review显示文摘Radiology education and training is of paramount clinical importance given the prominence of medical imaging utilization in effective clinical practice.The incorporation of basic radiology in the medical curriculum has continued to evolve,focusing on teaching image interpretation skills,the appropriate ordering of radiological investigations,judicious use of ionizing radiation,and providing exposure to interventional radiology.Advancements in radiology have been driven by the digital revolution,which has,in turn,had a positive impact on radiology education and training.Upon the advent of the corona virus disease 2019(COVID-19)pandemic,many training institutions and hospitals adhered to directives which advised rescheduling of non-urgent outpatient appointments.This inevitably impacted the workflow of the radiology department,which resulted in the reduction of clinical in-person case reviews and consultations,as well as in-person teaching sessions.Several medical schools and research centers completely suspended face-to-face academic activity.This led to challenges for medical teachers to complete the radiology syllabus while ensuring that teaching activities continued safely and effectively.As a result,online teaching platforms have virtually replaced didactic face-to-face lectures.Radiology educators also sought other strategies to incorporate interactive teaching sessions while adopting the e-learning approach,as they were cognizant of the limitations that this may have on students’clinical expertise.Migration to online methods to review live cases,journal clubs,simulation-based training,clinical interaction,and radiology examination protocolling are a few examples of successfully addressing the limitations in reduced clinical exposure.In this review paper,we discuss(1)The impact of the COVID-19 pandemic on radiology education,training,and practice;(2)Challenges and strategies involved in delivering online radiology education for undergraduates and postgraduates during the COVID-19 pandemic;and(3)Difference between the implementation of radiology education during the COVID-19 pandemic and pre-COVID-19 era. | Md Anwarul Azim Majumder Uma Gaur Keerti Singh Latha Kandamaran Subir Gupta Mainul Haque Sayeeda Rahman Bidyadhar Sa Mizanur Rahman Fidel Rampersad | 2021 | World Journal of Radiology2021，13，11： | 0 |
