Abstract
A temperature control system consisting of a thermistor, signal proces sor, and computer algorithm was developed for magnetic resonance (MR) microscopy of small live animals. With control of body temperature wit hin +/-0.2 degrees C of the set point, heart rate is stabilized and, i n turn, repetition time (TR) during cardiac-gated studies is less vari able. Thus, image quality and resolution are improved.
