    "abstract": "The evaluation of blood compatibility of biomaterials is crucial for ensuring the clinical safety of implantable medical devices. To address the limitations of traditional testing methods in real-time monitoring and electrical property analysis, this study developed a portable electrical impedance tomography (EIT) system. The system uses a 16-electrode design, operates within a frequency range of 1 to 500 kHz, achieves a signal to noise ratio (SNR) of 69.54 dB at 50 kHz, and has a data collection speed of 20 frames per second. Experimental results show that the EIT system developed in this study is highly consistent with a microplate reader ( \n\u751f\u7269\u6750\u6599\u7684\u8840\u6db2\u76f8\u5bb9\u6027\u8bc4\u4f30\u662f\u786e\u4fdd\u690d\u5165\u5f0f\u533b\u7597\u5668\u68b0\u4e34\u5e8a\u5b89\u5168\u6027\u7684\u5173\u952e\u3002\u9488\u5bf9\u4f20\u7edf\u68c0\u6d4b\u65b9\u6cd5\u5728\u5b9e\u65f6\u76d1\u6d4b\u548c\u7535\u5b66\u7279\u6027\u5206\u6790\u65b9\u9762\u7684\u5c40\u9650\u6027\uff0c\u672c\u7814\u7a76\u5f00\u53d1\u4e86\u4e00\u79cd\u4fbf\u643a\u5f0f\u7535\u963b\u6297\u65ad\u5c42\u6210\u50cf\uff08EIT\uff09\u7cfb\u7edf\u3002\u8be5\u7cfb\u7edf\u91c7\u752816\u7535\u6781\u8bbe\u8ba1\uff0c\u5de5\u4f5c\u9891\u7387\u8303\u56f4\u4e3a1\uff5e500 kHz\uff0c\u572850 kHz\u9891\u7387\u4e0b\u4fe1\u566a\u6bd4\uff08SNR\uff09\u8fbe\u523069.54 dB\uff0c\u5e76\u5177\u590720\u5e27/s\u7684\u6570\u636e\u91c7\u96c6\u80fd\u529b\u3002\u5b9e\u9a8c\u7ed3\u679c\u8868\u660e\uff0c\u672c\u7814\u7a76\u5f00\u53d1\u7684EIT\u7cfb\u7edf\u4e0e\u9176\u6807\u4eea\u5728\u6297\u51dd\u725b\u8840\u4e2d\u5bf9\u5de5\u4e1a\u7ea7\u949b\u91d1\u5c5e\uff08TA3\uff09\u548c\u949b\u5408\u91d1\u2014\u2014\u949b6\u94dd4\u9492\uff08TC4\uff09\u6eb6\u8840\u884c\u4e3a\u7684\u68c0\u6d4b\u7ed3\u679c\u9ad8\u5ea6\u4e00\u81f4\uff08 ",
