肿瘤热疗是什么

肿(zhong)(zhong)瘤(liu)热(re)(re)疗(liao)(liao)是利用射(she)频(pin)电磁(ci)波(bo)(bo)、微(wei)波(bo)(bo)或超声(sheng)波(bo)(bo)等各种致热(re)(re)源(yuan)的热(re)(re)效应(ying),将肿(zhong)(zhong)瘤(liu)区加热(re)(re)至(zhi)有效治(zhi)疗(liao)(liao)温度范围并维持一段时间,使肿(zhong)(zhong)瘤(liu)组织发生(sheng)即(ji)时性的代谢反(fan)应(ying),从而(er)引起(qi)肿(zhong)(zhong)瘤(liu)细胞分(fen)子结构(gou)发生(sheng)改(gai)变和溶酶(mei)体活(huo)性增(zeng)强,达到杀灭肿(zhong)(zhong)瘤(liu)细胞,治(zhi)疗(liao)(liao)肿(zhong)(zhong)瘤(liu)的目的。

福州怎么买球自主(zhu)研发的(de)(de)荧(ying)光(guang)光(guang)纤测(ce)(ce)(ce)(ce)温系统为射(she)频(pin)热(re)疗提供测(ce)(ce)(ce)(ce)温辅(fu)助(zhu),其可以在射(she)频(pin)电(dian)场(chang)下准确的(de)(de)进行温度测(ce)(ce)(ce)(ce)量,精(jing)(jing)度为1℃(可定(ding)制高精(jing)(jing)度)。结合对肿(zhong)瘤组(zu)织的(de)(de)热(re)场(chang)仿真,可以通过少(shao)数(shu)测(ce)(ce)(ce)(ce)量点推测(ce)(ce)(ce)(ce)肿(zhong)瘤不问整体的(de)(de)温度分布情况。经过对实(shi)验结果的(de)(de)分析和数(shu)据处理(li),验证了的(de)(de)肿(zhong)瘤射(she)频(pin)热(re)疗仪能(neng)够达到(dao)设计(ji)要求,具有医疗领域的(de)(de)实(shi)际(ji)应用。

肿瘤热疗为什(shen)么(me)需要测(ce)温(wen)

目前市场上的所(suo)有肿(zhong)瘤(liu)(liu)体(ti)外射频热疗机在(zai)肿(zhong)瘤(liu)(liu)热疗过程(cheng)中(zhong)缺乏有效(xiao)的、可行的肿(zhong)瘤(liu)(liu)温(wen)度(du)在(zai)线监测方法。传统的电(dian)子(zi)温(wen)度(du)传感器(qi),如热敏电(dian)阻、热电(dian)偶等,容易受电(dian)磁(ci)波(bo)干扰,无法实时在(zai)加热过程(cheng)中(zhong)正常测温(wen),难(nan)以准确确定肿(zhong)瘤(liu)(liu)部(bu)位温(wen)度(du)以及肿(zhong)瘤(liu)(liu)周围正常组织(zhi)温(wen)度(du),严重影响热疗效(xiao)果。

相对于传统的(de)温度传感器测量方法具有(you)很(hen)多的(de)不可(ke)比拟(ni)的(de)优(you)点:光(guang)(guang)波不会发生(sheng)电(dian)磁(ci)干(gan)扰,也不会被电(dian)磁(ci)波所干(gan)扰,而且容(rong)易被各种光(guang)(guang)敏探测器感知接(jie)收,很(hen)容(rong)易地将(jiang)光(guang)(guang)信(xin)号转换为(wei)电(dian)信(xin)号或者将(jiang)电(dian)信(xin)号转换为(wei)光(guang)(guang)信(xin)号,与现代(dai)电(dian)子设备和计算机(ji)可(ke)以(yi)进行良好的(de)匹(pi)配,光(guang)(guang)纤(xian)的(de)工(gong)作(zuo)频谱宽,动(dong)态范围大(da)(da),是一种损耗(hao)较低的(de)优(you)良的(de)传输(shu)线,光(guang)(guang)纤(xian)本(ben)身不带(dai)电(dian)也不导电(dian),绝缘性能好,抗辐(fu)射性能好,可(ke)弯曲,质量轻体积小,可(ke)应用在其它类(lei)型传感器无(wu)法满(man)足条件(jian)的(de)严(yan)(yan)苛环(huan)境中,例(li)如空间大(da)(da)小受到(dao)严(yan)(yan)格限制、易燃(ran)、易爆或者有(you)强电(dian)磁(ci)干(gan)扰等恶劣环(huan)境。

荧光(guang)(guang)(guang)(guang)测温(wen)所采用的(de)(de)(de)工作(zuo)机理是。当(dang)某种(zhong)材料(liao)受到(dao)(dao)紫外光(guang)(guang)(guang)(guang)、可见光(guang)(guang)(guang)(guang)或者红外光(guang)(guang)(guang)(guang)的(de)(de)(de)照射激发时,产(chan)生的(de)(de)(de)一种(zhong)光(guang)(guang)(guang)(guang)发射现(xian)象就是光(guang)(guang)(guang)(guang)致发光(guang)(guang)(guang)(guang)现(xian)象。在光(guang)(guang)(guang)(guang)致发光(guang)(guang)(guang)(guang)现(xian)象当(dang)中,出射荧光(guang)(guang)(guang)(guang)的(de)(de)(de)参数与所在环境(jing)的(de)(de)(de)温(wen)度(du)有紧密的(de)(de)(de)对应关系(xi),要得到(dao)(dao)所需(xu)要的(de)(de)(de)温(wen)度(du)信息,只需(xu)要检测其荧光(guang)(guang)(guang)(guang)的(de)(de)(de)强度(du)或者荧光(guang)(guang)(guang)(guang)寿命(ming)即可。

荧(ying)(ying)光(guang)寿命(ming)型温度(du)(du)(du)传感器(qi)的荧(ying)(ying)光(guang)寿命(ming)与温度(du)(du)(du)的对应关系不(bu)(bu)会因为光(guang)强的改变而发生(sheng)改变,具有自校(xiao)准(zhun)性,热容小(xiao),响(xiang)应速(su)度(du)(du)(du)快等优点。荧(ying)(ying)光(guang)光(guang)纤测温系统(tong)可以在(zai)射频电场下不(bu)(bu)受干扰准(zhun)确的进行温度(du)(du)(du)测量;
