Brain image
The images produced by the optical coherence tomography system are significantly sharper than those produced by MRI or ultrasound equipment, Kang said, and should give surgeons a better look at the boundaries of a tumour and the presence of blood vessels and healthy tissue that must be preserved..
A Johns Hopkins electrical engineer is building a tool to help brain surgeons locate and get a clear look at cancerous tissue.
In some cases, the device could eliminate the need to cut into the brain for a traditional biopsy, a procedure that can pose risks to the patient.
Researcher Jin U Kang said: 'The idea is to provide instant high-resolution pictures of a small segment of the brain without actually touching the tissue.
'These pictures could let the doctor conduct a “virtual biopsy” to see where the tumour is and whether it is benign or malignant.
'And when it's time to cut out the cancer, these images could help a surgeon see and avoid healthy tissue.'
Kang's concept recently received a financial boost that should help move it from the drawing board to the operating room.
