Purpose: In this study, we developed and estimated the home-made patient-respiration-training-system (PRTS) by using the micro-electro-mechanical-system (MEMS) which can help to avoid the problems for the limitation of the RGRT applicable patient cases.
Methods: We compared the response of the PRTS with period of real movement and commercially introduced real time patient monitoring (RPM) system. We measured the response of the PRTS by using the respiratory gating platform (RGP) for a 2.5, 3.0 and 3.5 second of the period and a 20, 30, 40 mm of the amplitude. Under the same condition, we measured the response of the RPM system by using the RGP.
Results: The period error from the PRST was measured as 0.6~6.0% compared with period of real movement. Considering the overall shape of the graphs, the uncertainty of the signal of the RPM system measured about 1% in an amplitude for each interval, on the other hand, MEMS signals had 3~11% of the error in amplitude.
Conclusion: In term of simplicity and convenience, we found the possibility of PRTS as the patient training system and we expect more detail of study for more realistic situation can be established, in near future.
