Sensor improves digital x-rays
SFU assistant professor of engineering science Karim Karim won the prestigious Douglas Colton Medal for his work on amorphous silicon X-ray image sensors, boosting the potential use of large-scale digital x-ray procedures. Karim overcame the fuzzy images that plagued large-format digital x-ray fluoroscopy by amplifying the x-ray signal at the pixel level using amorphous silicon technology. “The pixel amplifier enables the low-dose fluoroscopy x-ray signal to ovecome the noise of the external imaging electronics and create a clearer image,” Karim says. Large format digital x-ray imaging can provide instantaneous results, making it ideal for remote diagnosis – for instance in medical consultations over the telephone or Internet. An added bonus of Karim’s pixel amplifier is that patients may require lower radiation dosages when undergoing diagnostic x-ray imaging. For more information
