Abstract

Fast-speed volumetric imaging methods are desired for both multiphoton and confocal microscopy. A tilted-plane volumetric imaging and reconstruction method was developed to achieve fast volumetric imaging of freshly biopsied/excised human skin tissue based on only xy laser scanning. A volume that covers a surface area of 10 mm × 8 mm and a thickness of 80 um can be acquired in 9 minutes. The large surface area was achieved by stitching multiple volume strips and each volume strip was reconstructed from a sequence of frames acquired along the tissue surface at a frame rate of 198 frames per second and each frame was captured in an imaging plane that is tilted relative to the tissue surface. The imaging method was implemented on a multimodality imaging system to generate confocal reflectance, second harmonic, and two-photon fluorescence volumes simultaneously and give complementary information of the excised tissue. Application in skin cancer surgery guidance will be pursued in the future.
