## Abstract MRI with hyperpolarized gases, ^3^He, ^129^Xe, ^13^C, and others, has the potential to become an important diagnostic technique for clinical imaging. Due to the nonreversible loss of magnetization in hyperpolarized gas imaging, the choice of the flip angle is a major factor that influen

## Abstract Multiple‐channel RF transmission holds great promise for MRI, especially for human applications at high fields. For calibration it requires mapping the effective RF magnetic fields, __B__, of the transmitter array. This is challenging to do accurately and fast due to the large dynamic r

Electronic calipers, now included as standard in most commercial ultrasonic scanners, are used for a variety of measurements including fetal cephalometry ( 1 ) . They operate by generating two electronic pulses which brighten the A-scan or B-scan display, or both. The position on the time-base at wh
