Abstract

Total Skin Electron Beam Therapy (TSEBT) of linear accelerator has become use so as to be useful, 2~9 MeV of energy territories came to be used with mycosis fungoides and cutaneous lymphomas in the superficial lesion treatment which covers the major portion of the body. I treat a patient to Stanford technique in this study, and it is $60^{\circ}$ around the patients whom Stanford technique irradiated electronic beam to a linear accelerator in horizontal directions and there is a way a standard of TSEBT treat it to six located field (anterior, posterior, and four obliques) becoming. An each field does horizontally it and consist to beam of the two component which fitted the center to a suitable angle. a patient treats it to three dual field a day in order to make short treatment time. when a first day, we treat one dual field at anterior position and two dual field at posterior position. when the second day, treat one dual field at posterior position and two dual field at anterior position. Therefore, six dual field is finished in perfect periodic two days. we made cylindrical acrylic phantom, and I inserted a dosimeter film between phantom. in order to measure a dose distribution calculation before treat a patient, and a patient checked it in six field directions that got from a treatment. It is after that thermoluminescent dosimetry (TLD) as it uses Rando phantom and then measurement dose distribution in six field directions after attaching at chest, the right and left flank, a back after irradiation.

선형 가속기의 Total Skin Electron Beam Therapy (TSEBT)는 유용하게 사용 되어왔으며, 2에서 9 MeV 에너지 영역의 전자는 mycosis fungoides와 cutaneous lymphomas와 같은 신체의 큰 부분을 덮는 표면상의 병변 치료에 사용 되어져 왔다. 본 연구에서는 Stanford technique로 환자를 치료 하였으며, Stanford technique는 선형 가속기로 전자 빔을 수평 방향으로 조사하여 서 있는 환자의 주위에 $60^{\circ}$로 위치한 6개의 조사면(anterior, posterior, 그리고 4개의 obliques)으로 치료하는 TSEBT의 표준이 되는 방법이다. 각 조사면은 수평으로 하고 적절한 각도에 점을 맞춘 두 개 성분의 빔으로 이루어져있다. 치료시간을 짧게 하기 위해 환자는 하루에 세 개의 이중 조사면으로 치료한다. 첫째 날에는 anterior로 하나의 이중 조사면, posterior에서 두 개의 이중 조사면 그리고 그 다음날에 posterior에서 하나의 이중 조사면 그리고 anterior 경사에서 두 개의 이중 조사면으로 치료한다. 따라서 6개의 이중 조사면의 완전한 주기는 2일로 완성된다. 환자를 치료하기 전 먼저 선량 측정을 하기 위해 원통형 아크릴 팬텀을 제작하여 그 사이 선량계 필름을 삽입하고 환자가 치료 받는 6개 조사면 방향으로 조사를 한 후 선량 분포를 알아보았다. 그런 후 Rando 팬텀을 사용하여 열형광선량계(thermoluminescent dosimetry : TLD)를 앞 가슴, 좌우 옆구리, 등에 부착한 후 6개 조사면 방향으로 방사선을 조사한 후 선량을 측정 하였다.
