제안 방법
- Also, in order to investigate the reproducibility of breathing in actual care units before the application of the audio-visual guidance system, we measured the averages of the PTP of free breathing, respiratory cycles, and the changes in the superficial contents of respiratory functions in the CT room and the care units respectively. As for the measured average values, the PTP value was 0.
- Developing our own respiratory guidance system for maintaining stable and regular breathing among patients in the course from the CT scan to radiation treatment, this study has compared free breathing and audio-based breathing with voice files, and measured and quantitatively analyzed respiratory signals via the comparison with our own developed voice and image based respiratory system. In doing this, we would like to evaluate the usefulness of our institution’s own developed respiratory guidance system in the course of the respiratory gating radiation therapy.
- In order to compare respiratory data from each system, we respectively obtained data from free breathing without any application of the systems, from the application of the auditory guidance system, and from the simultaneous visual and auditory system of respiratory stability developed by our institution. For the purpose of the evaluation of the usefulness of the respiratory guidance system in the course of treatment, we obtained data by measuring respiratory signals with or without the application of the respiratory guidance system for 5 minutes a day over a 5 day period 3days after the attainment of the signals.
- The first part is a 17” LCD monitor (Multisync LCD 1770NX, NEC) put in a cassette holder for those who have bad vision or are abhorrent of watching a screen closely, while the second is a 8” LED monitor (WINDOM, CT-M080B LED) put in a monitor arm with 6 joints with which CT scans are possible without collision with the bore by adjusting the angle after putting on a table.
- The respiratory signal obtaining system used in this study consists of the Ream-Time Position Management System (RPM, Varian) using infrared cameras and reflectors and the interface (RPM Computer, Varian) showing signals real time. As seen in Fig.
- By means of the subjects’ respiratory data obtained in this way, we yielded the PTP (peak to peak) of each respiratory cycle, and the superficial contents of the respiratory cycles and functions. Then, we yielded the standard deviations of these items and examined the changes in respiratory cycles and the similarities among respiratory volumes. Also, we evaluated the usefulness of the respiratory guidance system via t-test of the standard deviations.

- 2, the system puts the infrared reflectors on a certain abdomen site and then visualizes time and position information. The CT simulator used in the experiment is BrightSpeed Elite (GE) and the linear accelerator is Trilogy (Varian, USA).
- 1). This study took as its subjects 7 patents who underwent the respiratory gating radiation therapy from June 2011 to April 2012.
- This study took as its subjects 7 patients who received the respiratory gating radiation therapy from June 2011 to April 2012 in order to examine the inspiratory with the use of our own developed respiratory guidance equipment. Of the subjects, 4 had lung cancer and 3 liver cancer.
