论B超在医学诊断中的作用

说是说回家立刻就写,格雷特还是多做了几天实验,把数据补充完整,才开始动笔。才写了个标题,赶紧划掉:

太放松了,前世的词儿带出来太多了。这个世界的人,根本不知道什么叫B超

他把上面一行字涂黑,另起一行,在灯下奋笔疾书。培训班给学员的住宿条件不错,房间虽然不大,书桌上的台灯却是魔法灯,而不是光线昏暗、火焰还摇摇晃晃的油灯。

灯光雪白,亮度差不多相当于25瓦的日光灯,发光均匀稳定或许还太亮了一点。格雷特最近正在琢磨着,要不要给它加个淡黄色的罩子

他用鹅毛笔蘸了蘸墨水,挥动笔杆。轻盈流畅的笔迹一行行落在纸上,梳理着思路,把第一次出现在这个世界的魔法编织成型:

回声魔法的一种新应用,以及该应用在探查人体内部脏器上的作用

关键词:音波,范围和清晰度,探查,医疗

在研究回声魔法的过程中,我们注意到一点:不同种类蝙蝠发出的音波,在探查周围环境方面,效果有所不同。

举例说明,在同样的魔力消耗下,以普通褐蝙蝠作为施法材料,探查兔子体内脏器时,回声在冥想视野当中,可以清楚地反馈兔笼、桌子和10平方米之内的房间轮廓,但是对兔子内脏的描绘并不清晰;

毛翼蝙蝠,探查范围缩窄至兔笼、桌子和地面,但是对兔子内脏的反馈,较前者稍稍清晰;

小菊头蝠,探查范围增长至整个房间,约50平方米范围,但是对兔子的内脏,显示极其模糊;

显示范围和兔子内脏描绘,见下方对比图

鉴于以上实验结果,我们可以初步认定,音波穿透力越强,探查的范围越广,然而显示的清晰程度越低;穿透力越弱,探查的范围越小,然而对探查对象的细节部分,显示得越清晰。

为此,我们用市面上能找到的47种蝙蝠为材料蝙蝠名单见附录一,逐一做了实验。最后发现,用短耳吸血蝠的大脑作为实验材料,能够最清晰地探查人体内部的脏器情况。

该魔法的法术模型为

施法材料:短耳吸血蝠大脑,需保持完整。本作者用新鲜品、石灰吸水后的干品,以及用冷冻射线处理过的冻品各20只,做了对比实验,结论是,魔力消耗、探查范围、显示清晰度,均无统计学意义上的区别。

实验数据见下表

施法时的注意点:需将待检查部位剃光毛发,涂抹传导液,以便回声顺利传导入人体。本作者用不同类型的液体做了对比实验,结论是传导液以甘油为最佳,甜杏仁油次之。

不同类型液体对施法效果的影像见下表

回声魔法的该种应用,能够实时、动态、清晰地显示人体脏器形态、解剖层次及毗邻关系,以及血管和其他管状结构的分布。

该种应用,是一种无创的检查方法,无需切开人体、显露内部,就能显示人体内部的脏器。施法方便,成本低廉,可以多次、反复进行,患者无创伤、无痛苦。

笔者用30只活鹅做了肝脏部分的探查实验,得出的反馈图景,能很好地反映鹅肝的育肥情况。由此可以合理推断,该种魔法也可以用来检查,人体肝脏是否沉积了过多脂肪。
