Simulation of an imaging system for internal contamination of lungs using MPA-MURA coded aperture collimator
Ting Zhang, Lei Wang, Jing Ning +4
The nuclides inhaled during nuclear accidents usually cause internal contamination of the lungs with low activity. Although a parallel-hole imaging system, which is widely used in…
OCT-GAN: Single Step Shadow and Noise Removal from Optical Coherence Tomography Images of the Human Optic Nerve Head
Haris Cheong, Sripad Krishna Devalla, Thanadet Chuangsuwanich +8
Speckle noise and retinal shadows within OCT B-scans occlude important edges, fine textures and deep tissues, preventing accurate and robust diagnosis by algorithms and clinicians.…
DeshadowGAN: A Deep Learning Approach to Remove Shadows from Optical Coherence Tomography Images
Haris Cheong, Sripad Krishna Devalla, Tan Hung Pham +9
Purpose: To remove retinal shadows from optical coherence tomography (OCT) images of the optic nerve head(ONH). Methods:2328 OCT images acquired through the center of the ONH using…
A Deep Learning Approach to Denoise Optical Coherence Tomography Images of the Optic Nerve Head
Sripad Krishna Devalla, Giridhar Subramanian, Tan Hung Pham +7
Purpose: To develop a deep learning approach to de-noise optical coherence tomography (OCT) B-scans of the optic nerve head (ONH). Methods: Volume scans consisting of 97 horizontal…
