Sensor Aboard Proba-V Satellite to Help Detect Skin Cancers
http://www.medgadget.com/wp-content/uploads/2015/03/Proba-V-satellite.jpg
Velcro and pressurized pens are a repeated lore of the tech**logies that have come out of space programs, but many devices originally developed to orbit around Earth have made even more impact on the people below than Velcro. **w a new example of such translational research has led to a sensor created for the**European Space Agency’s Proba-V satellite being tested for use in detecting skin cancers.
The camera aboard the Proba-V scans vegetation, detecting subtle variations in the health of the plants using both visual and near-infrared detectors. Because the satellite*was designed to scan the entire Earth every*couple of days, the resolution and sensitivity of the sensors is quite incredible. Near-infrared has been used for a number of years already in helping to find and assess skin lesions, but the sensor within the Proba-V satellite is substantially more capable than any similar device previously developed. Xenics, the*Belgian company that developed the sensor, is **w testing the device for clinical applications, hopefully leading to the fact that a vegetation satellite will have led to the early detection of thousands of cancer cases.
More from the European Space Agency:
The Proba-V camera captures a 2250 km-wide picture of the land below on every sweep, made possible by Xenics’ 3072-pixel line sensor. Unlike conventional rectangular detectors, like those used in consumer digital cameras, this sensor captures information one line at a time, which it can do very rapidly. It builds up a complete imageas the target moves past– more efficient for imaging rapid objects on production lines.
In the medical sector, Xenics are **w adapting their tech**logy to improve a doctor’s ability to diag**se skin diseases. Scanners have been giving detail-rich cross-section images of living tissue for some 20 years, but the space camera’s sensitivity at certain wavelengths means it can see deeper to help diag**se skin diseases such as cancer.
The game-changers here are the significantly higher sensitivity achieved by the sensor and the speed, making it possible to complete the scan in a reasonable time.
