Frequency and Power Considerations for , EPR and Related Techniques,of the subject. Theoretical power deposition in some idealised sample shapes is presented, along with some corroborative animal results. Power absorption depends substantially on the orientation of the subject relative to the RF field. The simple loop surface coil is shown to lead to higher absorpti记忆 发表于 2025-3-25 12:44:05

Stable Soluble Paramagnetic Compounds,. In particular, these compounds act as spin probes, molecules that can be directed to various tissue fluids via spin probe design and report back environmental conditions. Aspects of the environment that are reported by spin probe spectrum include the following: concentration of other paramagnetic新鲜 发表于 2025-3-26 02:16:38

The Measurement of Oxygen in Vivo Using EPR Techniques,imetry also will have significant applications in clinical medicine. The characteristics of EPR oximetry that appear to be especially useful often are complementary to existing techniques for measuring oxygen in tissues. These characteristics include capabilities of making repeated measurements from服从 发表于 2025-3-26 22:49:51
