Abstract: The present disclosure is associated with monitoring health of a patient. An example photoacoustic monitoring device includes a light-guiding component to guide light energy toward tissue to cause the light energy to be absorbed by the tissue; an ultrasound transmission component to transmit acoustic energy toward the tissue to cause a biological response from the tissue; and a sensing component to perform one or more of ultrasound or photoacoustic imaging to sense the biological response from the tissue and permit a status of the tissue to be determined. In some implementations, the biological response is sensed based on the light energy absorbed by the tissue during the biological response caused by the acoustic energy transmitted toward the tissue.

Abstract: The present disclosure is associated with monitoring health of a patient. An example electromagnetic-evoked acoustic device includes an electromagnetic component to emit energy toward tissue of a patient to cause the energy to be absorbed by the tissue; an ultrasound transmission component to transmit acoustic energy toward the tissue to cause a biological response from the tissue; and an ultrasound sensing component to sense the biological response from the tissue to permit a status of the tissue to be determined, wherein the biological response is sensed based on the energy absorbed by the tissue during the biological response.
