Intraoperative ultrasound imaging is used in brain tumor surgery to identify remnants. The images may some cases be more difficult interpret the later stages of operation than beginning operation. aim this paper explain causes surgically induced artefacts and how they can recognized reduced.The theoretical reasons for are addressed impact discussed.
