CerebroSense: A Brain Pulsatility Measurement Device

Invention Summary:

During craniotomy, surgeons often determine the level of brain swelling based on finger tactile sensation in order to implement compensation measurements. However, under or over compensation can lead to severe complications such as cerebral ischemia.

Researchers at Rutgers University and Stevens Institute of Technology have developed a portable device, CerebroSense, that utilizes a non-invasive sensing technology to provide a non-contact, quantitative, and real-time assessment of brain volume variations (pulsatility) during open brain surgery. CerebroSense has an ultrasound sensor and a Raspberry Pi camera sensor mounted on a rotating fixture being attached to an adjustable stand with an easy-to-roll base. Such a design facilitates the placement of CerebroSense in the surgical area. Data collected will be simultaneously processed and analyzed by a computer to provide real-time pulsatility readings accessible to both the neurosurgeon and anesthesiologist. It allows physicians to make accurate compensation decisions during open brain operation.

Market Applications:

  • Digital assessment of brain volume variations during open brain surgery
  • Digital assessment of volume variations of heart, lung and other pulsating organs during surgery


  • Non-invasive
  • Quantitative assessment of brain volume variations
  • Real-real time monitoring of brain volume variations
