Abstract :
Invasive intracranial pressure (ICP) sensors are potentially dangerous for neurosurgical patients. The problem of non-invasive ICP monitoring is analyzed, the new non-invasive method and technique in accordance with the developed ultrasonic transit time method is proposed and a computer based ICP waves´ measuring system is introduced. The resolution of this system is less then 0.1 mmHg and the measuring channel´s capacity is above 1.0 kbit/s which allows one to resolve up to 11 harmonics of ICP pulse waves. The results of clinical tests and simultaneous comparative analysis of invasive and non-invasive ICP measuring systems´ data are shown and discussed
