Using a needle, doctors more accurately extract suspicious tissue for analysis, thereby eliminating painful surgery. This procedure also eliminates scarring or disfigurement, requires half the time of traditional techniques, reduces exposure to x-rays and greatly reduces costs. MRI and CAT Scans Digital signal processing was pioneered at NASA for use during the Apollo Lunar landings to computer-enhance pictures of the Moon.
Cancer cells exude nitric oxide.
This causes changes in blood flow in tissue surrounding cancer that can be detected by the sensor. It causes no discomfort to the patient and uses no ionizing radiation. NASA uses the microgravity of space to grow human tissue for research and transplantation and to gain valuable knowledge important to the treatment of cancer. The NASA-designed Bioreactor is a unique tissue culture chamber, the size of a home sewing machine, that grows cells in three dimensions. These tissues, similar to tissues found in the body, will help scientists understand cancer growth and how the human immune system responds.
