Abstract: A portable two-mode probe to be applied against a biological tissue to be examined, the probe including an ultrasonic transducer configured to emit ultrasonic waves into the tissue and to receive ultrasonic waves reflected by the tissue, the transducer extending along a transverse axis; and at least two optodes placed on either side of the transverse axis, such that the transducer extends between the two optodes. Further, each optode includes a casing containing a light emitter configured to emit a light wave toward the tissue, and/or an optical detector configured to detect a light wave scattered by the tissue. The optodes are arranged such that at least one light emitter and at least one optical detector are placed on either side of the transducer, and at least one optical detector has a detection area formed from a semiconductor and connected to a circuit board.

Abstract: A portable two-mode probe intended to be applied against a biological tissue to be examined, the probe comprising: an ultrasonic transducer (34, 63), configured to emit ultrasonic waves into the tissue and to receive ultrasonic waves reflected by the tissue, the transducer extending along a transverse axis; at least two optodes (32, 60, 62a, 62b) placed on either side of the transverse axis, such that the transducer extends between the two optodes; each optode comprising a casing (52, 61), the casing containing: a light emitter (31), configured to emit a light wave toward the tissue; and/or an optical detector (32), configured to detect a light wave scattered by the tissue; the optodes being arranged such that at least one light emitter and at least one optical detector are placed on either side of the transducer; at least one optical detector having a detection area (53, 63a, 63b) formed from a semiconductor and connected to a circuit board (54).
