Design of MRI interventional RF coil / 医疗卫生装备

ABSTRACT

Objective To design a new type of RF endorectal coil so as to increase signal to noise ratio(SNR) and improve the efficiency of MRI diagnosis.Methods Through circuit and construction optimization,a MRI model of coil in vivo was designed.Results The images and spectroscopy of a special phantom were acquired and the results were compared to those of the commercial TORSO coil.Conclusion This coil gives a significantly higher SNR at the region of interest(ROI).The achieved high local SNR and resulting high spatial resolution can add more anatomic and biochemical information to the diagnosis of prostate diseases.
