Final answer:
Endoscopy uses fiber optics and cameras to visualize the internal organs, not X-ray technology. It allows doctors to explore the body, perform surgeries, and obtain samples for examination.
Step-by-step explanation:
An endoscope is a device used by doctors to explore the body through various orifices or minor incisions. It works by transmitting light down a fiber bundle to illuminate internal parts, and the reflected light is transmitted back out through another bundle to be observed. This allows doctors to perform surgeries, such as arthroscopic surgery, and obtain samples for examination.
Endoscopy does not use X-ray technology. Instead, it relies on fiber optics and cameras to visualize the internal organs. The images captured by the camera can be viewed on a screen or transmitted to an eyepiece. The use of endoscopy has revolutionized medicine by enabling minimally invasive procedures and accurate diagnoses.
