The construction of two novel mult-segment (MS) resonators are described. The signal-to-noise ratio (SNR) and B1 homogeneity of the coils are compared with that of a surface coil and a standard quadrature head coil. The images obtained with the MS designs revealed a surface coil-like fall-off in signal with depth. The SNR offered by MS coils was found to be better than the head coil at depths less than approximately 6 cm. Bilateral motor cortex activation on normal subjects performing finger tapping tasks is demonstrated.

Teleotolaryngology is becoming a reality as a result of improvements in technology and telecommunications. This prospective, clinical trial was designed to demonstrate the utility of three telemedicine systems in an otolaryngology practice. Optel is a desktop system used in the office. Picasso is a mobile system used from various locations throughout the hospital. The Georgia Statewide Telemedicine Program (GSTP) is a large, sophisticated system used from a fixed site within a rural hospital. Patients with a wide variety of ear, nose, and throat problems were presented to consultants at two medical teaching centers in Georgia. Fifty-four consults were completed over a 24-month period. In addition, three teleconsultations demonstrated enhanced capabilities for continuing medical education (CME) and health care networks. Nine different specialty fields were accessed by the otolaryngologist. Five consults were completed via the Optel system; 13 via the Picasso system; and 36 via GSTP. Overall, teleotolaryngology provided quality audio and visual communication between the physicians that significantly improved diagnostic capabilities and treatment options for the patient.
