    摘要： In a photoacoustic measurement apparatus and a photoacoustic measurement system, a region of interest useful for the evaluation of blood flow is set. A subject is avascularized while changing the avascularization pressure between the avascularized condition and the non-avascularized condition. A receiving circuit (21) receives a detection signal obtained by detecting a photoacoustic wave generated in the subject by emission of measurement light to the subject. Photoacoustic image generation means (25) generates a photoacoustic image based on the detection signal of the photoacoustic wave. Motion detection means (31) detects the motion of each of a plurality of control points set in each photoacoustic image based on photoacoustic images at a plurality of times. Region of interest setting means (32) sets a region of interest based on the motion detected at each control point. Blood flow information generation means (27) generates blood flow information based on the signal strength of the photoacoustic image in the region of interest.

    摘要： An embodiment of this invention provides an ultrasound device and a method of assessing a bone of a subject. The ultrasound device assesses a bone of a subject in at least two modes comprising a first mode and a second mode. The ultrasound device comprises: a selecting unit configured to select a mode from the at least two modes; a first ultrasound probe configured to transmit an ultrasound signal to the bone; a second ultrasound probe configured to receive the ultrasound signal from the bone; an assessing unit configured to derive a first parameter indicating one or more characteristics of the bone based on the selected mode and the ultrasound signal received by the second ultrasound probe; and a coupler for coupling the first ultrasound probe and the second ultrasound probe, the coupler being configured to be switched to a first configuration in the first mode and to a second configuration in the second mode. A face of the first ultrasound probe and a face of the second ultrasound probe are oriented in substantially a same direction in the first configuration, and in substantially an opposite direction in the second configuration. An embodiment of this invention improves the flexibility of usage of the ultrasound assessment device.

    摘要： Provided are body fat measuring techniques employed to date, usually applying a certain level of force to the tissue causing narrowing of the adipose tissue layer at the time of measuring. This creates a bias in the adipose layer thickness measurement results that is not accounted for when employing these methods. Provided is a current apparatus and method offering a solution for accounting for this bias thus improving the accuracy of body fat measurements.

    摘要： The invention relates to a contact determination apparatus for determining a degree of contact between a device (2) and a moving object (3), wherein the contact determination apparatus comprises a motion distribution providing unit for providing a motion distribution being indicative of motion in the surrounding of the device and a contact determination unit (14) for determining a degree of contact between the device and the object based on the provided motion distribution. Since the degree of contact between the device and the object is determined based on the provided motion distribution and not simply based on, for instance, a peak of an A-mode signal, the determination of the degree of contact can be less disturbed by artifacts like ring-down artifacts or by blood scattering, if the object is, for instance, tissue. This can lead to a more accurate determination of the degree of contact.
