Recently, scientists from several universities and hospitals in the UK have collaborated to develop a laser detector that converts brain cell spectral signals into audio, allowing doctors to "listen" to distinguish cancer cells from healthy cells. New technologies can help doctors complete brain surgery more quickly and safely.
The new laser detector was improved on the basis of last year's research and development. The previous detectors also help doctors identify areas of cancer cells in the brain, but they can only be visualized through the display. The new detector converts the map signal into an audio signal, allowing the doctor to "listen" to the cancer cells in the brain, thereby focusing the eye on the surgical site. Matthew Baker of the University of Strathclyde, who participated in the study, said that the new technology can accurately signal the guidance, allowing doctors to focus on surgery.
Preliminary test results show that doctors rely on laser detectors to identify healthy cells and cancerous cells with an accuracy of up to 70%. Baker said that although the accuracy is 90% lower than the spectral signal, they are confident that they will continue to improve through improvement.
For patients with brain cancer, cancer cells that have not been cleared will leave recurrence and metastasis, while the removal of healthy cells will damage the nerve function and cause serious side effects. Next, they will strive to conduct early clinical trials of laser detectors to help doctors remove cancerous brain cells as much as possible without removing healthy cells.
