Abstract
In a method to determine the spatial distribution of the specific absorption rate in tissue that represents a measure of the absorption of electromagnetic fields emitted by means of a radiation generating element, at least one item of measurement information acquired by a thermoacoustic computed tomography device is used to determine the specific absorption rate.
Claims15
A method to determine the spatial distribution of the specific absorption rate (SAR) in biological tissue, comprising the steps of:
- obtaining measurement information from a subject containing biological tissue by thermoacoustic computed tomography (TCT);
- and
- in a processor, automatically determining a spatial distribution of the SAR in the subject using said measurement information obtained by TCT.
A medical device comprising:
- a magnetic resonance (MR) scanner, configured to receive an examination subject therein containing biological tissue, said MR scanner being configured to acquire MR measurement data from the examination subject;
- a thermoacoustic computed tomography (TCT) detector system integrated into said MR scanner, that acquires TCT measurement data from the examination subject in the MR scanner;
- and
- a computerized evaluation unit, supplied with said MR measurement data and said TCT measurement data, which automatically determines a spatial distribution of the specific absorption rate of the biological tissue in the examination subject using said TCT measurement data.
