in the surgical treatment of malignant tumors, it is crucial to characterize the tumor as precisely as possible. the determination of the exact tumor location as well as the analysis of its properties is very important in order to obtain an accurate diagnosis as early as possible. in neurosurgical applications, the optical, non-invasive and in situ techniques allow for the label-free analysis o...

Intracranial tumors are a type of cancer that grows spontaneously inside the skull. Brain tumor is cause for one in four deaths. Hence early detection important.
