A model of acoustic absorption in fluids based on a continuous distribution of relaxation times
Ultrasound ablation for cancerous tumours convert acoustic energy to heat causing cell death and destruction of tumours. The paper describes a rigorous method for modelling the absorption of acoustic energy in tissue. It allows a more accurate description of the power law of absorption in tissues than previously used, based on a continuous distribution of relaxations. The method is being used in treatment planning software, developed as part of an EPSRC-funded (EP/F025750/1) consortium of UCL, ICR and Oxford University. Currently, clinical trials are being planned with a surgery team (lead surgeon - Prof. Brian Davidson) at the Royal Free Hospital.
