Abstract
Bone age assessment plays an important role in medical applications. Traditionally, Tanner-Whitehouse Method is commonly adopted by most physicians to evaluate the bone age of hand radiogram. Although only 20 regions of the hand radiogram are examined against standard radiograms of different growth stages, it is still tedious, time-consuming, and inconvenient if the standard charts are not readily available, and certain trainings are required for the evaluation because the assessment results are easily-affected by different physicians. In thesis, a web-based TW3 bone age assessment system in the Cloud is proposed and implemented using PHP and MySQL to provide a convenient way of performing TW3 evaluation on hand X-ray images. Physicians can perform TW3 evaluation anywhere whenever they can login in the system through internet, free of the limitation of printed standard growth-stage radiograms. Meanwhile the system can also offer a platform in which medical personnel, including physicians, technicians, and nurses can easily learn and/or practice the TW3 evaluation method. The system improved over previous web-based version in three ways: (1) reduced mouse-clicks: only twenty-one mouse clicking times needed to complete the scoring job; (2) enhanced data protection and application scope by more user classes: this system set up the concept of class, each class has its own data access right. (3) system in the cloud, thus reducing the cost of server hardware and maintenance cost.
