    摘要: A method is disclosed for determining a signal's time of arrival at a receiver device, the signal being transmitted by a transmitter device to the receiver device. The method comprises correlating the signal as transmitted by the transmitter device and the signal as received by the receiver device with each other. The signal comprises in its frequency spectrum a first signal component spanning a first frequency range, a second signal component spanning a second frequency range and a third signal 5 component spanning a third frequency range. The first frequency range and second frequency range are separated by a first intermediate frequency range that does not contain a signal component of the signal. The second frequency range and third frequency range are separated by a second intermediate frequency range that does not contain a signal component of the signal. The method further comprises, based on the performed correlation, determining said time of arrival.

    摘要: A method for generating hardness information of tissue subject to a varying pressure. The method comprises receiving signals from the tissue from a sensor for measuring the deformation of the tissue in a measuring plane defined by the sensor, which sensor, during a varying pressure exerted on the tissue, is moved along the tissue in a direction transverse to the measuring plane; identifying strain of the tissue from the resulting signals; and relating the strain to elasticity and/or hardness parameters of the tissue. The method may comprise the step of displaying elasticity and/or hardness parameters of a tissue surface or tissue volume part extending practically parallel to the direction of motion of the sensor.
