During neuroendoscopic surgery of, for example, brain tumors, the characteristics of the operating space, usually narrower than that of other endoscopic surgeries, are determined by visual inspection through the endoscope. However, when bleeding occurs, the surgical site is covered in blood, disrupting visualization. The surgeon may intend to resect a tumor with minimal hemorrhage but can unintentionally cut a blood vessel in the tumor that could not be confirmed visually. Therefore, identification of the presence of blood vessels during brain tumor resection is critical. So far, a number of studies have developed methods to detect invisible blood vessels. Nonetheless, further development of such methods is crucial.
