Making doctor’s job easy and patient’s pain less; researchers have created a new camera that can look everything inside a human body.

The process that was conducted previously by X-rays or endoscopy, researchers from the University of Edinburgh have lightened it up by creating the camera that can allow doctors to look everything happening under our skin, no matter where it is; a task that was difficult to achieve previously.

The camera works while paired up with an endoscope – a slim, long device with camera, sensors and lights at its tip. The camera picks up the light emitted out by the endoscope through the photon detectors inside it. The camera has the ability to sense light sources behind as much as 20 centimeters (7.9 inches) of a body tissue, informed Futurism.

The camera unites the light signals with the scattered photons which enables the device to see where the endoscope is in the body. Through a technique known as ballistic imaging where the scattered and the direct photons are differentiated, the exact location of the bodily interior could be seen, something that can be very beneficial for treatments.

Publishing their study in Biomedical Optics Express, the senior researcher Professor Kev Dhaliwal expressed, “This is an enabling technology that allows us to see through the human body. The ability to see a device’s location is crucial for many applications in healthcare, as we move forwards with minimally invasive approaches to treating disease.”

Though it not yet known when the camera would actually be used for proper clinical treatments, but the researchers aim to further develop the device in advancing the images and diagnostic technologies. If the camera is successfully implemented, it can make the process easier and cut down on other methods such as X-rays, according to Science Alert.
