Intraoperative integrated ultrasound is practically a real-time intraoperative image guidance modality that is acquired several times during an operation for a brain tumour.
The images acquired are electronically fused with the conventional image guidance, based on the preoperative MRI. Intraoperative ultrasound is now used as a standard intraoperative tool to provide a real time progress of the operation and the relationships of the surgical cavity with important surrounding structures that need to be protected during the operation.
