摘要
用水、盐,聚氯乙烯粉和羧甲基纤维钠四种材料配制成一种适用的微波体模(模拟肌肉组织)。该体模的复介电系数在300～2500MHz范围内与实际人体肌肉组织的误差≤5％。这种体模的优点是材料立足国内,价廉,室温下配制,使用方便。本文也给出这种体模的温度特性,稳定性和热学特性,供电磁场生物效应和微波热疗等研究使用。
<ABSTRACT>
A new kind of microwave phantom muscle tissue was developed. The
ingredients for the phantom muscle tissue consist of water, salt, polyvin-
yl chloride powder and cellulose carboxymethalate.
The differences of permittivities between the phantom and actuanl
muscle are less than 5%for 300-2500MHz The advantages of the
phantom muscle tissue are low-cost and easy to prepare at room tempere
ure. The characteristics of the phantom muscle tissue are also given.
