Abstract
The use of lung ultrasound in the screening, diagnosis, and evaluation of interstitial lung disease has been relatively well studied, but has not been widely accepted and applied in clinical practice. There are also some differences in the examination methods applied in these studies. This paper summarized the application, advantages, and disadvantages of lung ultrasound in the diagnosis and follow-up of interstitial lung disease by comprehensively reviewing the examination methods, research results and progress of new technologies of lung ultrasound in interstitial lung disease.

Abstract
The TG21 protocol introduced the Ngas calibration method for parallel plate chambers in high-energy electron beams. This calibration method was performed for a Markus parallel plate chamber in proton and electron beams of various energies as well as a 60Co beam. For an individual chamber, the Ngas value in proton beams differs from the Ngas value in cobalt and electron beams by the ratio of (W/e) for proton beams to that of a 60Co beam. While the replacement correction factor is essential for Markus chambers in low-energy electron beams, the results of our Nppgas measurements in proton beams showed that the Markus chamber does not need a replacement correction factor for therapeutic proton beams of energy 20-170 MeV. These results indicate that the 0.7-mm guard ring of the Markus chamber is adequate to prevent the in-scattering of secondary electrons produced by proton irradiation of the chamber wall or medium.
