LMap: Shape-Preserving Local Mappings for Biomedical Visualization
Saad Nadeem, Xianfeng Gu, Arie Kaufman
Visualization of medical organs and biological structures is a challenging task because of their complex geometry and the resultant occlusions. Global spherical and planar mapping…
Spherical Parameterization Balancing Angle and Area Distortions
Saad Nadeem, Zhengyu Su, Wei Zeng +2
This work presents a novel framework for spherical mesh parameterization. An efficient angle-preserving spherical parameterization algorithm is introduced, which is based on dynami…
C2A: Crowd Consensus Analytics for Virtual Colonoscopy
Ji Hwan Park, Saad Nadeem, Seyedkoosha Mirhosseini +1
We present a medical crowdsourcing visual analytics platform called C{}A to visualize, classify and filter crowdsourced clinical data. More specifically, CA is used to buil…
Visualization Framework for Colonoscopy Videos
Saad Nadeem, Arie Kaufman
We present a visualization framework for annotating and comparing colonoscopy videos, where these annotations can then be used for semi-automatic report generation at the end of th…
Corresponding Supine and Prone Colon Visualization Using Eigenfunction Analysis and Fold Modeling
Saad Nadeem, Joseph Marino, Xianfeng Gu +1
We present a method for registration and visualization of corresponding supine and prone virtual colonoscopy scans based on eigenfunction analysis and fold modeling. In virtual col…
FeatureLego: Volume Exploration Using Exhaustive Clustering of Super-Voxels
Shreeraj Jadhav, Saad Nadeem, Arie Kaufman
We present a volume exploration framework, FeatureLego, that uses a novel voxel clustering approach for efficient selection of semantic features. We partition the input volume into…
Radiative Transport Based Flame Volume Reconstruction from Videos
Liang Shen, Dengming Zhu, Saad Nadeem +2
We introduce a novel approach for flame volume reconstruction from videos using inexpensive charge-coupled device (CCD) consumer cameras. The approach includes an economical data c…
Crowd-Assisted Polyp Annotation of Virtual Colonoscopy Videos
Ji Hwan Park, Saad Nadeem, Joseph Marino +3
Virtual colonoscopy (VC) allows a radiologist to navigate through a 3D colon model reconstructed from a computed tomography scan of the abdomen, looking for polyps, the precursors…
Crowdsourcing Lung Nodules Detection and Annotation
Saeed Boorboor, Saad Nadeem, Ji Hwan Park +2
We present crowdsourcing as an additional modality to aid radiologists in the diagnosis of lung cancer from clinical chest computed tomography (CT) scans. More specifically, a comp…
GlymphVIS: Visualizing Glymphatic Transport Pathways Using Regularized Optimal Transport
Rena Elkin, Saad Nadeem, Eldad Haber +4
The glymphatic system (GS) is a transit passage that facilitates brain metabolic waste removal and its dysfunction has been associated with neurodegenerative diseases such as Alzhe…
Quantification of Local Metabolic Tumor Volume Changes by Registering Blended PET-CT Images for Prediction of Pathologic Tumor Response
Sadegh Riyahi, Wookjin Choi, Chia-Ju Liu +8
Quantification of local metabolic tumor volume (MTV) chan-ges after Chemo-radiotherapy would allow accurate tumor response evaluation. Currently, local MTV changes in esophageal (s…
Reproducible and Interpretable Spiculation Quantification for Lung Cancer Screening
Wookjin Choi, Saad Nadeem, Sadegh Riyahi +3
Spiculations are important predictors of lung cancer malignancy, which are spikes on the surface of the pulmonary nodules. In this study, we proposed an interpretable and parameter…
