Gastroscopy-conjugated photoacoustic and ultrasonic dual-mode imaging for detection of submucosal gastric cancer: in vitro study |
Comparison between the normal gastric tissue and cancer for different degrees of differentiation. First row shows the pathological images of gastric cancer and normal tissue [panels (a), (b), (c), and (d)], second row shows the photo images [panels (e), (f), (g), and (h)]. The last row shows the corresponding reconstructed 3D PA images [panels (i), (j), (k), and (l)] of gastric cancer and normal tissue. |
