Abstract
Cryosurgical procedure utilises multiple probes positioned invasively into the body. The probe tip is brought in contact with the tissue, freezing it at a pre-determined low temperature. The process promotes tissue necrosis or death to cancer cells. Liquid Nitrogen (LN2) which is made to flow through the inner walls of the cryogenic probe is utilised in this research. The perennial issue concerning cryosurgery is the monitoring of the ice formation and thermal representation on the surrounding tissue. For instance, it is imperatively desirable to encroach the entire tumour volume with ice but also having conservative concern on the nearby healthy tissues. Freezing healthy tissues could pose undesirable side effects such as: incontinence and urethrorectal fistula brought about by freezing the urethra in cryosurgery of prostate cancer. A method of thermal modelling is introduced in this research by simulating the individual ice ball formation and setting the temperature contour level around the region of interest.
