May enable real-time LV wall thickness assessment; leaves open clinical validation before practice adoption.
The switched gain technique simplifies ultrasonic measurement of cardiac wall thickness by overcoming dynamic range limitations to display both endocardial and epicardial surfaces simultaneously.
Griffith et al. (1975) studied Cardiac wall thickness measurement. Switched gain technique for pulse-echo ultrasound was evaluated. A switched gain technique for pulse-echo ultrasound was developed to allow simultaneous real-time visualization of both endocardial and epicardial surfaces of the left ventricular posterior wall.
