Popis:	Volumetric MRI thermometry is undergoing active development. The measurement bases on the resonance response of protons insidemolecules (i.e., water, fat, methylene, lipids) of the examined body. The difference between resonance frequencies gives information about the temperature of the tissue. Various MR thermal image construction methods exist because temperature influences the state of a living object in numerous ways. As a result of this, contrast characteristics of MR images of tissue depend on the value of the magnetic field induction, tissue characteristics itself, and temperature. This paper deals with brain temperature measurement based on digital analysis of T 2-weighted MR images. MR images of homogenous and inhomogeneous phantoms at different temperatures were analyzed. The relationship between image brightness, temperature, and phantom composition was determined. The temperature of the cerebrospinal fluid was calculated.
