Coil Orientation and Stimulation Threshold in Transcranial Magnetic Stimulation (TMS).

Transcranial Magnetic Stimulation (TMS) is used to treat mental disorders and explore brain function via applied electromagnetic fields generated by a high current coil placed on the subject's scalp. While TMS has been in clinical use for decades, and continues to be a rapidly expanding therapeutic modality, there are still many unknowns regarding how stimulation parameters may affect treatment efficacy and how they may be optimized. One key parameter that is readily accessible is coil orientation and its effects on TMS stimulation threshold.

Radio-frequency tracking of respiratory equipment: rationale and early experience at the Cleveland Clinic.

Background: When respiratory therapists (RTs) seek respiratory care equipment, finding it quickly is desirable, both to expedite patient care and to avert RTs wasting time. To optimize RTs' ability to quickly locate ventilators, we developed and implemented a radio-frequency identification (RFID) tagging system called eTrak.

Methods: The Clinical Engineering and Information Technology groups at Cleveland Clinic collaboratively developed a Wi-Fi-based RFID program that used active RFID tags.

Dual-source CT coronary angiography: image quality, mean heart rate, and heart rate variability.

Objective: The purpose of this study was to evaluate the effect of mean heart rate and heart rate variability on the image quality of dual-source CT coronary angiography.

Subjects And Methods: Eighty patients underwent dual-source CT coronary angiography. Thirteen data sets were reconstructed in 5% steps from 20-80% of the R-R interval.
