優(yōu)勢(shì)特點(diǎn)：

1. 可在CT、PET、SPECT、光學(xué)成像、正常實(shí)驗(yàn)環(huán)境工作
2. PC實(shí)時(shí)顯示監(jiān)測(cè)生理參數(shù)波形及數(shù)值、門控點(diǎn)設(shè)置等信息
3. 模塊化設(shè)計(jì)，用戶根據(jù)需求選配，節(jié)約實(shí)驗(yàn)成本
4. 可監(jiān)測(cè)呼吸心電體溫等參數(shù)
5. R波門控延遲可由用戶設(shè)置，呼吸門控寬度可由用戶設(shè)置
6. 可選配脈搏血氧、EtCO2、有創(chuàng)血壓、光纖測(cè)溫及通氣輔助等功能
7. 可搭配核磁兼容模塊，兼容MR環(huán)境，可在高磁場(chǎng)環(huán)境下工作
