Abstract Intraoperative assessment of breast surgical margins will be of value for
reducing the rate of re-excision surgeries for lumpectomy patients. While
frozen-section histology is used for intraoperative guidance of certain cancers,
it provides limited sampling of the margin surface (typically <1??%?? of the
margin) and is inferior to gold-standard histology, especially for fatty tissues
that do not freeze well, such as breast specimens. Microscopy with ultraviolet
surface excitation (MUSE) is a nondestructive superficial optical-sectioning
technique that has the potential to enable rapid, high-resolution examination of
excised margin surfaces. Here, a MUSE system is developed with fully automated
sample translation to image fresh tissue surfaces over large areas and at
multiple levels of defocus, at a rate of ~5??min??/??cm2. Surface extraction is
used to improve the comprehensiveness of surface imaging, and 3-D deconvolution
is used to improve resolution and contrast. In addition, an improved fluorescent
analog of conventional H&E staining is developed to label fresh tissues within
~5??min for MUSE imaging. We compare the image quality of our MUSE system with
both frozen-section and conventional H&E histology, demonstrating the
feasibility to provide microscopic visualization of breast margin surfaces at
speeds that are relevant for intraoperative use.
