The agar phantoms were generated using thermal seed implant templates with the following features: single stars; 2 stars; 3×3 array of exclusive fabrics; 4×4 array row cloth; double layers 4×4 different spacing row cloth. A thermocouple was implanted to measure the temperature of the agar phantom. The agar phantom was then placed on poles to provide a magnetic field to heat the thermal seeds. In models containing one or two thermal seeds, the temperature reached 25~32℃ upon heating. This heating function of the thermal seeds was also stable. In another model containing nine thermal seeds, the temperature reached 37.5℃ between two thermal seeds, while the temperature 1.0cm away from the thermal seed array was 30.1℃. In a model containing 16 thermal seeds, the center of the thermal seed array center reached 52.9℃ after applying the magnetic field. In tests of different spatial distances of the thermal seed in the magnetic field, the temperature at the center reached ≥65℃, and progressively decreased with increasing distance from the focal point, dropping to 42~45℃ at 1.0cm away from the thermal seed array. Comparing models with a layer spacing of 1.0cm and 0.8cm, the difference in temperature was approximately, 1.0℃. In comparisons of tests with layer spacing of 1.0cm and 0.5cm spacing, the temperature difference between the measured points was about 3.0℃. Here, we have shown that, in an experimental model of muscle(agar phantom), magnetic induction of thermal seeds within a specific target area can provide a temperature suitable for cancer thermal ablation., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null,

articleAbstract=为了探讨不同数量和不同排布方式下，热籽在等效肌肉的琼脂体模中磁感应升温效果，制作琼脂等效肌肉模型，利用模板植入不同数量热籽：1颗、2颗、3×3阵列排布、4×4阵列排布、双层4×4不同层间距排布。在选择的测温点植入热电偶，将植入完成的琼脂体模置于磁极下，进行磁场辐照，测定并记录升温情况。结果表明，1颗和2颗热籽植入体模在磁场中加热后温度可达25～32℃，热籽在体模中的发热功能稳定。9颗热籽植入体模在磁场中加热后，两颗热籽间温度达到37.5℃，热籽阵外1.0cm处温度为30.1℃。16颗热籽植入体模在磁场中加热后，热籽阵列中心温度达到52.9℃。不同层间距热籽植入体模在磁场中加热后，中心点位置温度均达到65℃以上。随着逐渐远离中心点，温度呈下降趋势，在热籽阵外1.0cm处降至42～45℃。层间距1.0cm与0.8cm的结果比较，各测温点间温度相差约1.0℃；层间距1.0cm与层间距0.5cm的结果比较，各测温点间温度相差约3.0℃。因此，本研究成功模拟了等效肌肉的琼脂体模，一定数量的热籽在既定靶区磁感应升温，可以达到肿瘤治疗所需温度。,
