供应商全称:北京日泰科技有限公司
(四)申请理由及相关说明
理由及说明:光声成像是未来各类临床重大疾病医学检测设备的发展趋势,在生物医学工程研究中具有不可替代的地位。此次拟购买的高频超声成像仪,通过二次开发能实现光声和超声的双模态成像系统,可以在疾病检测中同时提供丰富的功能和结构性信息,大大提高临床疾病的诊断准确性,提升南科大生物医学影像等方向的研究水平,为南科大其他院系的相关研究提供服务。此外,该设备还可用于开展研究各种荧光纳米粒子在生物组织中的应用,能够进一步完善生物医学工程系公共实验室平台建设。经调研:1、国内产品的成像帧频<100帧/秒,国外也只有Verasonics公司的高频超声成像仪的成像帧频可达14000帧/秒,是唯一能满足生物医学工程系开展光声和超生双模态成像以及荧光成像方面研究要求的产品;2、国内的产品无法满足超声采集发射的自由编程控制,国外也只有Verasonics公司生产的高频超声成像仪能够完成对超声的采集、发射进行自由的编程控制;3、国内产品的每通道平均输出功率达不到8W,最高输出功率达不到100W;国外只有Verasonics公司生产的高频超声成像仪每个通道平均输出功率能达到8W,最高输出功率能达到100W,实现在一个超声探头上同时进行超声发射与回波采集。
