-- / Ultrasound imaging is one of the most important ways of imaging the human body. The mainly application of ultrasound is for the soft parts of the body, due to the properties of tissues in the propagation of the ultrasounds. The brain with its normal shape is an appropriate organ for ultrasound imaging. But intraoperative ultrasound imaging may be effective in tumor localization and it can be used throughout surgery to monitor the extent of tumor resection. The ability to locate precisely a deeply situated intracranial lesion intraoperatively can reduce the risk of damage to normal tissue, assist in determining the extent of tumor resection and reduce the time surgery.
Intraoperative ultrasound holds great promise, but if it is to be used to its fullest extent, further modification of transducers must be developed. For this reason in this project we have done different simulations via the program Field II in order to evaluate the most appropriate transducers for the best depiction that can be achieved. We have to mention that those different experiments are based to the same code but with different specific parameters in every experiment.
