Pulsed HIFU is hypothesized to alter permeability of the extracellular matrix by altering the collagen network. In this study, the ability of HIFU to disrupt the extracellular matrix, particularly Type I collagen, in vitro, was investigated in order to enhance the drug delivery to highly collagenous tumors. This was tested in vitro in two ways, first using dye penetration, and second, by confocal reflection microscopy. Based on the analyses, it was concluded that there was at least a three-fold increase in porosity of the collagen gels after HIFU treatment.
