Vertical probing used in addition to horizontal probing in echoencephalographic examination of patients allows more exact localization of the volumetric process, especially one situated parasagittaly. Transducers of three frequencies, 0.88, 1,76, and 2.64 m. c. s., are used in the examination of patients. It is shown that transducers with higher frequencies, 1.76 and 2.64 m. c. s., have advantages over a transducer with a frequency of 0.88 m. c. s.
在对患者进行脑回波描记术检查时，除水平探测外还使用垂直探测，这样能更精确地定位体积性病变，尤其是位于矢状窦旁的病变。对患者进行检查时使用三种频率的换能器，分别为0.88、1.76和2.64兆周/秒。结果表明，频率较高的换能器，即1.76和2.64兆周/秒的换能器，比频率为0.88兆周/秒的换能器具有优势。
