Computer Simulation for Training the Proper Use of Personal Protective Equipment

Computer Simulation for Training the Proper Use of Personal Protective Equipment

The use of personal protective equipment  is one of the basic infection control precautions in health care. The effectiveness of personal protective equipment  is highly dependent on adequate staff training. In this project, a computer simulation pro...
Predicting quality of life using machine learning on community health data

Predicting quality of life using machine learning on community health data

Missing data is a common issue in community health and epidemiological studies. Direct removal of samples with missing data can lead to reduced sample size and information bias, which deteriorates the significance of the results. While data imputation...
Using machine learning to predict mortality after bladder cancer surgery

Using machine learning to predict mortality after bladder cancer surgery

Bladder cancer is a common cancer in genitourinary malignancy. For muscle invasive bladder cancer, surgical removal of the bladder, i.e. radical cystectomy, is in general the definitive treatment which, unfortunately, carries significant morbidity...
Stereoscopic 3D visualization for immersive and intuitive anatomy learning

Stereoscopic 3D visualization for immersive and intuitive anatomy learning

Conventional anatomy education makes use of two-dimensional (2D) images of three-dimensional (3D) anatomical objects to illustrate their spatial locations and interrelationships. Good visual-spatial ability is needed to mentally transform or fuse multiple...
A Virtual Reality Based Simulator for Nasogastric Tube Placement Training

A Virtual Reality Based Simulator for Nasogastric Tube Placement Training

Nasogastric tube (NGT) placement is a common clinical procedure where a plastic tube is inserted into the stomach through the nostril for feeding or drainage. However, the placement is a blind process in which the tube may be mistakenly inserted into...
