Neuraxial Anesthesia: Curvilinear array

A curvilinear probe with transmit frequencies between 2-5 MHz is recommended for neuraxial anesthesia. The lower frequencies provide a sufficient depth of field for high BMI patients while maintaining adequate resolution to detect the relatively large, coarse tissue features of interest—such as ligaments and spinal bones.
