Unformatted text preview: Damages normal tissue which can limit utility Limited Utility against Extensive, Systemic Disease (Unless tumor cells can be specifically targeted, eg. With Tumor-specific antibody delivering bound-metal for microwave heating) Can be valuable for Debulking large local tumor or reducing tumor size to permit surgery Second Malignancies can be induced Combine with radio-sensitizers which can improve anti-tumor cells specifically. Application of Ultra-Sound to Attached Cells (in situ or metastatic) Cell must detach and round up in order to divide Attached cells can be made Modulation of Ultra-Sonic Treatment Can vary the sonic frequency (wavelength) Can vary the intensity Can vary the timing to correspond with cell cycle and cell treatment responses. Opportunity for multiple ultra-sonic treatments repeated at minutes, hours, or days. 13:42 13:42...
