Introduction In the advent of modern research facilities and advanced knowledge in the scientific field, many technological applications were developed as a means of improving people’s lives. Different advancements in scientific areas of discipline paved the way for beneficial inventions and innovations especially in the medical field. Radiology, for example, provided human beings the ability to explore his anatomy without surgery. There are many other examples of these advantageous technologies available to us in the modern times. A very good example of technology’s benefits to human health is the development of a bone density test that only requires knowledge on radiation. It is important to check the density of the bone since it relates to a disease called osteoporosis. Osteoporosis is a disease of the bones characterized by the decrease in bone density due to lowering calcium levels and many other factors. It can be prevalent for a very long time, unnoticed by a patient suffering from it, unless a fracture transpires or unless detected by a bone density scan. This disease may be genetically caused or as an after-effect of medications such as steroids. It affects the way of life of the patient since it is directly linked to disability or death in the most serious cases (Hurd 2006). The x-ray scan can immediately detect the occurrence of osteoporosis since the results on the x-ray film show significant differences from bones of a normal person in terms of diameter and other physical characteristics. Although x-ray can be used, a recent bone density scan was developed, called the dual energy x-ray absorptiometry scan (DEXA) that works similarly on the principle of radiation, but on a more precise level. Bones Anatomy Bones, on the outside, are sturdy structures that protect and support the internal organs of the body and also affect the posture and overall shape of the body. It is composed of calcium and the inside of the bone is the literally the factory of blood cells. Ironically, the bone may seem to be lifeless but just like the skin and hair, it is continuously developing. This is evident in people who put extreme pressure to the bones such as weightlifters and athletes, who develop stronger bone structures. Women are more at risk in having osteoporosis since at the onset of menopause, there is a significant decrease in the levels of the hormone estrogen that prevents bone loss (“Osteoporosis”). Bones develop constantly in length gradually from the inside. Ossification, or the process of bone growth, is characterized by the alteration of a weaker material of connective tissue by a sturdier bony tissue. Osteoblasts slowly develop first, forming an osteocyte. This continuous process soon creates a primary ossified center in the bone until it proceeds to the tip of the bones. As a result, there would be an increase in length followed by the development of a secondary ossified center in the epiphyses. Then, the weaker cartilaginous materials are substituted for by compact bony tissues. Development occurs early in the womb until adolescence when most of the time, the bones are considered to be mature. Growth in length ceases by this time as it is controlled by t
