Stereotactic brain biopsy using stereotactic head frame such as CRW (Radionics, USA) has demonstrated a precise lesion localizing accuracy. In this study, we developed the target point calculation program for brain lesion biopsy using CRW stereotactic head frame and designed a phantom for verify the new developed program. The phantom was designed to have capability to simulate clinical stereotactic brain biopsy. The phantom has 10 vertical rods whose diameters are 6mm and tip of each rods are 2mm. Each rod has different length, 150 mm x 4 ea, 130 mm x 4 ea, 110 mm x 2 ea. CT images were acquired with Simens CT scanner as continuous transverse slice, 1 mm thickness in a 25 cm field of view and stored in a dicom file as a 256 x 256 matrix. As a result, the developed new target localization program will be useful for planning and training in complicated 3 dimensional stereotactic brain biopsy.

Objectives : The optimal treatment of craniopharyngioma is controversial. Despite recent advances in microsurgical management, complete surgical removal of craniopharyngioma remains very difficult. Radiation added to surgery is effective, but radiation therapy resulted in untoward side effect in young patient. Gamma knife radiosurgery offers the theoretical advantage of a reduced radiation dose to surrounding structures during the treatment of residual or recurrent craniopharyngioma compared with fractionated radiotheraphy. We described retrospective analysis of tumor size and clinical symptoms of patients after gamma knife radiosurgery in residual or recurrent craniopharyngioma were performed. Material and Methods : From September 1990 to January 2000, 18 patients of craniopharyngioma were treated by gamma knife radiosurgery. All patient had undergone surgery, but residual or recurrent tumor was found and all of them treated postoperative gamma knife radiosurgery. The mean age was 19(from 6 to 66) and male to female ratio was 10 to 8 and 8 patients were below 15 years old. In young age group(below age 15), the average volume of the tumor was $2904.8mm^3$ and mean maximal gamma knife dose was 34.9Gy. In old age group(older than 15), the average volume of the tumor was $2590.4mm^3$ and mean maximal gamma knife dose was 45.2Gy. The size of the tumor was average $2730.1mm^3$($88-12000mm^3$), mean average radiation dose was 40.7Gy and the mean prescription dose was 17.6 Gy(4-35Gy) delivered to a median prescription 50.7% isodose. Results : The follow up was from 1 year to 9 years(mean 59.1 months) after gamma knife radiosurgery. The tumor was controlled in 13(72.2%) patients. The tumor decreased in 9 patients and not changed in 4 patients. The tumor size increased in 4(22.2%) patients during follow up period. In two cases the tumor size increased because of its cystic portion was increased, but their solid portion of the tumor was not changed. In another two patients, the solid portion of the tumor was increased. So, one patient underwent reoperation and the other patient underwent operation and repeated gamma knife radiosurgery. The tumor recurred in one case(5.6%) that is a outside of irradiated site. The presenting symptoms were improved in 4 patients(improved visual acuity in 1, controlled increased intracranial presure sign in 3 patients). In one case, visual acuity decreased after gamma knife radiosurgery. The endocrine symptoms were not influenced by gamma knife radiosurgery. Conclusion : Craniopharyngioma can be treated successfully by gamma knife radiosurgery. Causes of the tumor regrowth are inadequate dose planning because of postoperatively poor margination of the tumor, close approximation of optic nerve and residual tumors outside the target lesion. Recurrence can develop 4 years after gamma knife radiosurgery. Volume is important, but the accurate targeting is more important to prevent tumor recurrence. If the tumor definition is not clear during planning gamma knife surgery, long-term image follow up is required.

목 적:본 연구의 목적은 기존 컴퓨터단층촬영(Computed tomography, 이하 CT) 스캔 방법 대신 3D 광학 스캐너 (3D optical scanner)를 이용하여 인체모형 팬텀의 표면 데이터를 획득하고 기존 CT 스캔 표면 데이터와 3D 광학 스캔 표면 데이터 차이를 비교 분석하는 것이며, 3D 광학 스캔 표면 데이터를 몬테카를로 시뮬레이션(Monte Carlo Simulation, MCs)에 적용하여 일반 촬영 에너지조건으로 팬텀 선량 평가와 영상 구현을 연구하는 것입니다. 연구방법: 일반촬영의 선량 평가를 위해 환자 표면 데이터를 얻을 때 3D 광학 스캐너를 활용할 것을 제안합니다. 우리는 3D 광학 스캐너(Go!SCAN SPARKTM, CREAFORM) 사용하여 기존 CT 스캔 방법을 대신해 인체모형 팬텀의 표면 데이터를 얻었습니다. 3D 스캔 표면 데이터를 정렬하고 편집하기 위해 Meshlab 프로그램을 이용하였으며, 3D slicer 프로그램을 이용하여 CT 스캔 표면 데이터와 3D 스캔 표면 데이터 차이를 정량적으로 비교분석 하였습니다. 또한 3D 스캔 표면 데이터 분석 프로그램(VXelements, CREAFORM)을 사용하여 인체 모형 팬텀의 재현성을 평가 하였습니다. SpekCalc 프로그램을 이용하여 X-ray beam 에너지 스펙트럼을 계산하고 Geant4 기반의 MCs인 TOPAS를 이용하여 X-ray Beam을 모델링 하였습니다. 인체모형 팬텀을 MCs에 적용 하여 일반촬영 에너지 조건으로 팬텀 선량을 평가하고 Phase space data 통해 영상을 구현을 연구 하였습니다. 결 과:3D slicer를 이용한 CT 스캔 표면 데이터와 3D 광학 스캔 표면 데이터의 정량적 비교 분석에서 Hounsdroff distance는 Average 2.45 mm, Dice coefficient는 0.97로 나타나 CT 스캔 표면 데이터와 3D 스캔 표면 데이터가 거의 일치하는 것을 확인할 수 있었습니다. 또한 인체모형 팬텀 재현성 평가에서 인체모형 팬텀의 AP position, RAO position, LAO position 기준으로 팔이 있는 팬텀의 error distribution은 2 mm 오차 범위에서 평균 89.78%가, 4 mm 오차 범위에서 96.05%가 일치하는 것으로 나타났으며, 팔을 제외한 경우 error distribution은 2 mm 오차 범위에서 평균 96.48%가, 4 mm 오차 범위에서 99.45%가 일치하는 것으로 나타나 3D 광학 스캐너의 표면 데이터 재현성이 우수한 것으로 나타났습니다. 인체모형 팬텀을 이용한 3D 스캔 표면 데이터를 MCs에 적용하여 전신일반촬영 에너지 조건으로 팬텀선량 평가가 가능하며, Phase space data 통해 영상을 구현할 수 있다는 것을 확인 하였습니다. 결 론:본 연구에서 3D 광학 스캐너를 사용한 인체모형 팬텀 데이터 획득은 기존 CT scan 방식보다 간편하고 방사선 노출 없이 다양한 위치와 균일한 표면 구조의 정보를 정밀하게 얻을 수 있으며 MCs을 이용한 선량계산이 가능하며, Phase space data 통해 영상을 구현이 가능함에 따라 앞으로 일반촬영 분야의 활용과 선량평가에 매우 유용할 것으로 생각 됩니다. Purpose:The purpose of this work is to acquire surface data of anthropromophic phantom using 3D optical scanner instead of conventional computed tomography (CT) scanning methods and to compare the differences between existing CT scan surface data and 3D optical scan surface data. also it is to apply 3D optical scan surface data to Monte Carlo simulations (MCs) to study whether phantom dose evaluation and image implementation are possible under general shooting energy conditions. Targets and Methods:We suggest utilizing a 3D optical scanner when obtaining patient surface data for dose evaluation of normal photography. We obtained surface data of anthropromophic phantom instead of conventional CT scanning methods using 3D optical scanners (Go!SCAN SPARKTM, CREAFORM). The Meshlab program was used to sort and edit 3D scan surface data, and the CT scan surface data and 3D scan surface data differences were quantitatively compared using the 3D slicer program. The reproducibility of the dummy phantom was also evaluated using the 3D Scan Surface Data Analysis Program (VXelements, CREAFORM). Using the SpekCalc program, the X-ray beam energy spectrum was calculated and the X-ray beam was modeled using TOPAS, a Geant4-based MCs. We applied the anthropromophic phantom to MCs evaluate the phantom dose in X-ray energy conditions and study whether the image can be implemented through phase space data. Result:Quantitative comparative analysis of CT scan surface data and 3D optical scan surface data using 3D slicer showed that Hounsdroff distance was Average 2.45 mm and Dice coefficient was 0.97, indicating a close match between CT scan surface data and 3D scan surface data. In addition, the anthropromophic phantom reproducibility assessment shows that the error distribution of the phantom with arms by AP position, RAO position, and LAO position of the anthropromophic phantom averaged 89.78% in the 2 mm error range and 96.05% in the 4 mm error range. MCs using anthropromophic phantom confirmed that 3D scan surface data can be applied to Monte Carlo simulation to evaluate phantom dose under X-ray energy conditions through phase space data. Conclusion:In this study, anthropromophic phan tom data acquisition using 3D optical scanners is simpler than conventional CT scan methods, provides precise information of various locations and uniform surface structures without radiation exposure, enables dosing using MCs, and enables image implementation through phase space data.
