Electromagnetic Heating in a Model of Frozen Red Blood Cells
Abstract
The purpose of this study was to examine the feasibility of a dry method of thawing frozen human red blood cells using radio frequency energy. Human red blood cells are stored for long periods by using cryoprotective agents and freezing at -80 C. Current practice is to thaw the frozen cells in a warm water bath before preparation for use. In the thawing process, a small percentage of units are contaminated by the water-borne bacteria. Evaluation of radio frequency energy deposition in a model of a standard blood bag was made using thermometric and thermographic dosimetry. The results of this study show the ability of a radio frequency coil irradiating system to produce uniform heating in a model blood bag. Further study is recommended to explore the development of a system that would quickly thaw multiple units of frozen red blood cells.
