Maximizing the Extent of Resection in High-Grade Glioma.
2019
High-grade gliomas (HGGs) are devastating tumors associated with one of the worst prognoses in oncology. Glioblastoma multiforme (GBM) is the most frequently reported histologic type, with a median survival after surgery and combined treatment with chemotherapy and radiotherapy of 12–16 months. Several studies have shown that the extent of resection (EOR) of the contrast-enhancing part of the tumor improves survival in patients with HGGs, although the quest to achieve optimal oncologic outcomes must be tempered with the neurologic result following radical resection. To date, limited evidence exists on the relationship between EOR and level of clinical benefit for patients with HGGs. Brown e…
A snapshot multi-wavelengths imaging device for in-vivo skin diagnostics
2020
A portable proof-of-concept prototype device for single snapshot capturing of four spectral line images has been designed, assembled and laboratory-tested. It comprises optical unit that ensures even illumination of the skin target area simultaneously at four laser wavelengths - 450 nm, 523 nm, 638 nm and 850 nm, double-camera image recording system, micro-computer managed operation system and a touch-screen display for image control and displaying the concentration distribution maps of four skin chromophores - melanin, oxy-hemoglobin, deoxy-hemoglobin and bilirubin. Besides, the device captures skin auto fluorescence image at 405 nm laser excitation to separate seborrheic keratosis from ot…
