Covid-19 first occurred in Wuhan, China in December 2019. Subsequently, the virus spread throughout the world and as of June 2020 the total number of confirmed cases are above 4.7 million with over 315,000 deaths. Machine learning algorithm...
Practical beam steering of X-ray beams on Elekta accelerators: The effect of focal spot alignment on beam (symmetry and position) and radiation isocentre (size and position) [0.03%]
Elekta加速器上X射线束的实际转向：焦点对准对束(对称性和位置)和辐射等中心(尺寸和位置)的影响

Acceptance and commissioning of a linear accelerator is the process of preparing it for clinical use. One of the initial important dosimetric tasks for X-ray beam set-up and use is to optimise the trajectory of the electron beam before it h...
Radiation exposure of interventional cardiologists during coronary angiography: evaluation by phantom measurement and computer simulation [0.03%]
冠状动脉造影过程中介入心脏科医生的辐射暴露：通过虚拟测量和计算机模拟进行评估
Younghoon Roh,Sora Nam,Bong-Ki Lee et al.
Younghoon Roh et al.
During interventional cardiological procedures, operators are exposed to patients' scatter radiation. Therefore, we measured the radiation exposure of the operator's eyeball, thyroid, and chest wall during angiography. We used the optically...
Automatic glaucoma screening using optic nerve head measurements and random forest classifier on fundus images [0.03%]
使用随机森林分类器和视神经头测量的基金图像实现自动青光眼筛选

Glaucoma is an optic neuropathy that gradually steals the patient's sight by damaging the optic nerve head (which is responsible for transferring images from the eye to the brain). Causing an estimated 12.3% of global blindness, glaucoma is...
Automated detection of diabetic retinopathy in fundus images using fused features [0.03%]
