    • An apparatus for measuring intracranial pressure constituted of a transmitter arranged to transmit a first acoustic signal through a first cranial point, a receiver arranged to receive a second acoustic signal from a second cranial point and a control circuitry. The control circuitry is arranged to extract from the detected second acoustic signal a first set of frequency components associated with the transmitted first acoustic signal and extract from the detected second acoustic signal a second set of frequency components associated with intracranial processes. The control circuitry is further arranged to determine intracranial pressure responsive to the extracted first set of frequency components and the extracted second set of frequency components.
    • 一种用于测量颅内压的装置,其由布置成通过第一颅点传送第一声信号的发射器,被布置为从第二颅点接收第二声信号的接收器和控制电路构成。 控制电路被布置成从检测到的第二声信号中提取与所发送的第一声信号相关联的第一组频率分量,并从检测到的第二声信号中提取与颅内过程相关联的第二组频率分量。 控制电路还被布置成响应于所提取的第一组频率分量和所提取的第二组频率分量来确定颅内压。
