Simulation of high-intensity focused ultrasound lesions in presence of boiling.
BACKGROUND The lesions induced by high-intensity focused ultrasound (HIFU) thermal ablations are particularly difficult to simulate due to the complexity of the involved phenomena. In particular, boiling has a strong influence on the lesion shape. Thus, it must be accounted for if it happens during the pulses to be modeled. However, no acoustic model enables the simulation of the resulting wave...
متن کاملFrench researchers at boiling point
Over 30,000 French scientists have signed an online petition to " save research " set up last month, with a pledge to stop their administrative duties unless the government starts listening to their complaints about funding. There is one signature for every minute that has passed since the petition — aiming to save the French public research base from the latest cuts imposed by the government —...
متن کاملHistological and biochemical analysis of mechanical and thermal bioeffects in boiling histotripsy lesions induced by high intensity focused ultrasound.
Recent studies have shown that shockwave heating and millisecond boiling in high-intensity focused ultrasound fields can result in mechanical fractionation or emulsification of tissue, termed boiling histotripsy. Visual observations of the change in color and contents indicated that the degree of thermal damage in the emulsified lesions can be controlled by varying the parameters of the exposur...
متن کاملCorrelation of Liquid Viscosity at the Normal Boiling Point
The importance of liquid viscosity in chemical process design makes it one of the most measured transport properties. Nevertheless, of the 1893 compounds in the DIPPR 801 pure-component database, liquid viscosity and its temperature dependence (at 1 atm, or 0.1 MPa) have been predicted for nearly 50% of the compounds because no experimental data are available. Unfortunately, prediction methods ...
متن کاملFast algorithm in estimating high intensity focused ultrasound induced lesions
High Intensity Focused Ultrasound (HIFU) has been emerging as a new and effective modality in non-invasive thermal ablation for cancers and solid tumours. Although a theoretical model is available for calculating thermal field and the consequent lesion production, its computation is too time-consuming (~ 1 day) for HIFU treatment planning on the site. In this study, several approximations were ...
