科学家已经设计了一种完全非创伤性的影像检查方法，具有核磁共振(MRI)的效果，但是免除了患者暴露于辐射的危险，从而创造了一种新型轻便灵活的MRI工艺。

Alexej Jerschow博士是纽约大学(New York, NY, USA)的生理化学助理教授，Norbert Müller博士是Linz大学(Austria)的生理有机化学教授，他们设计了一种低能量、非侵入的核子磁共振(NMR)工艺，该工艺无需外源性辐射波(RF)辐射。他们的检测工艺依赖于使用高度藕联的RT天线线圈，检测自发的质子旋转-噪音。

MRI给了临床医生通过使用RG放射方法从体外非侵入性观察体内软组织的情况。但是MRI的RF脉冲在患者和工作人员体内产生了热量，尽管安全法规已经规定了能量堆积的界限。

Non-invasive Imaging Better Than Standard MRI
 
Scientists have devised a totally non-invasive imaging method that provides the benefits of magnetic resonance imaging (MRI) while eliminating patients’ exposure to irradiation and creating the possibility of developing light, mobile MRI technology.

Dr. Alexej Jerschow, an assistant professor of physical chemistry at New York University (New York, NY, USA), and Dr. Norbert Müller, a professor of physical organic chemistry at the University of Linz (Austria), have devised a low-energy, non-invasive nuclear magnetic resonance (NMR) technique that does not require external radiofrequency (RF) irradiation. Instead, their method relies on the detection of spontaneous, proton spin-noise in a tightly coupled RF antenna coil.

MRI allows clinicians to non-invasively visualize soft tissue in the interior of the human body by applying RF irradiation. However, the MRI’s RF pulses deposit heat in patients and medical personnel, although safety regulations that limit energy deposition have long been established.
