Answer:
Option (1).
Explanation:
Dual x-ray absorptiometry technique is used for the evaluation of the bone mineral density. The bone densitometry is normally used in this technique to estimate the mineral content of bone.
The radiation dose in the absorptiometry is considerable and only small or low amount of radiation dose is considered. The heavy dose may cause health problems in the individual. The photon energies are used for the bone and soft tissue. The treatment of osteoporesis can be done by this technique.
Thus, the correct answer is option (1).
