Vertebra osteoporosis detection based on bone density using Index-Singh statistical blended method
Osteoporosis is a progressive decrease in bone density so that the bones
become brittle and broken. Bones are composed of minerals such as calcium and phosphate, so the bones become hard and solid. Many people do not realize that osteoporosis is a…
