一种重建图像具有不同的测试设备和B.重构的图像具有不同的激励电流

The radius of the test device was 2 cm (A1), 4 cm (A2) or 8 cm (A3). The excitation current was 100 μA (B1), 150 μA (B2), 200 μA (B3), 250 μA (B4), 300 μA (B5) or 500 μA (B6). The diameter of the rose stem was 5.68 mm, and the excitation current frequency was 1 kHz. The excitation current was 250 μA for一种那和the radius of the test device was 8 cm forB.。在每个图像的下部的蓝色区域表示的玫瑰的茎，绿色区域表示的背景盐溶液中，并将其他颜色表示，发生严重的噪音。
