Core Body Temperatures in Collegiate Marching Band Artists During Rehearsals and Performances.

Context: To our knowledge, no researchers have investigated thermoregulatory responses and exertional heat illness (EHI) risk factors in marching band (MB) artists performing physical activity in high environmental temperatures.

Objective: To examine core temperature (Tc) and EHI risk factors in MB artists.

Design: Descriptive epidemiology study.

Segmented motion compensation for complementary coded ultrasonic imaging.

Ultrasonic imaging using complementary coded pulses offers the SNR improvements of signal coding without the filter side-lobes introduced by single-transmit codes. Tissue motion between coded pulse emissions, however, can introduce high side-lobes caused by misalignment of complementary filter outputs. This paper presents a method for filtering and motion compensation of complementary coded signals appropriate for use in medical imaging.
