Dibrugarh district personal grant from Dr. John Berry White after he retired as the civil surgeon of Lakhimpur district. The medical school, "John Berry White Medical School" was set up in 1900 at Dibrugarh, and thus this premier institute started its history, and marked a new era in education. Assam Medical College has the pride of having the first Radiology department in India, as in 1910 two X-Ray machine (One 10MA and another 15MA) was bought from England, only 15 years after the discovery of X-Rays by Professor Wilhelm Conrad Roentgen in 1895-96. These two were the first X-Ray machines in India.
Roentgen stereophotogrammetry are accurately measured and the three-dimensional position of the markers is reconstructed using software. The change in the position (translation and rotation) of the prosthesis markers relative to the bone markers is then determined. The reported accuracy of RSA ranges between 0.05 and 0.5 mm for translations and between 0.15˚ and 1.15˚ for rotations (95% confidence interval). New RSA techniques that avoid the need for attaching markers to the prosthesis have been introduced. Roentgen stereophotogrammetry Roentgen stereophotogrammetry (RSA) is a highly accurate technique for the assessment of three-dimensional migration and micromotion of a joint replacement prosthesis relative to the bone
