Improving the Physical Exam with Technology - Point of Care Ultrasound

Point of Care Ultrasound is rapidly becoming standard of care for utilization in real time medical diagnostics and decision making. As such we sought to introduce ultrasound to medical students beginning in their first year and specifically incorporating it to mirror their physical exam teaching in the Practice of Clinical Medicine (PCM) course to help strengthen both their learning of the physical exam while also better understanding the utility of ultrasound use at the bedside. We sought to see if this strategy would result in improved examination scores via testing during their required objective structured clinical examination (OSCE) in the PCM course

High Speed Pupillometry

Measuring the parameters of the pupil in the human eye has become increasingly important in customised refractive surgery and other eye care applications. High-speed and high resolution CMOS cameras can be used to study the dynamics of eyelids and their interaction with the pupil at different illumination levels. We consider the problem of measuring the pupil size from a high-speed video. In particular, we develop a novel algorithm for setting intra-lid sectors for the detection and estimation of the pupil and iris outlines from a sequence of digital images. An application of the proposed methodology to the estimation of the pupil parameters during an eye blink is given
