摘要： A method of measuring the thickness of a biological tissue by ultrasounds and a device carrying out such method. The method is implemented with an ultrasound probe that emits ultrasonic pulses within a body under examination and receives echoes generated from structures of the body under examination. The probe includes an array of two or more electro-acoustic transducers and, in combination, means for processing the reception signals and means for orienting one or more lines of sight, along which the emission of the pulses and/or the reception of the echoes is focused, according to different angles with respect to an axis perpendicular to the emitting surface of the probe. The thickness of the biological tissue is calculated by the time interval between the reception of the first echo and the reception of the second echo, which are relevant to the same ultrasonic pulse emitted along at least a line of sight oriented along an axis perpendicular to the surface of the biological tissue, which is defined by the iteration of measurements with the line of sight oriented at different angles and with comparisons between the measured intensity values, the orientation corresponding to the axis perpendicular to the surface of the biological tissue being the one showing the maximum intensity of the first echo.

摘要： The invention concerns a manufacturing process, and the related micromachined capacitive ultra-acoustic transducer, that uses commercial silicon wafer 8 already covered on at least one or, more preferably, on both faces by an upper layer 9 and by a lower layer 9′ of silicon nitride deposited with low pressure chemical vapour deposition technique, or deposition LPCVD deposition. One of the two layers 9 or 9′ of silicon nitride, of optimal quality, covering the wafer 8 is used as emitting membrane of the transducer. As a consequence, the micro-cell array 6 forming the CMUT transducer is grown onto one of the two layers of silicon nitride, i.e. it is grown at the back of the transducer with a sequence of steps that is reversed with respect to the classical technology.

摘要： A magnet structure for a Nuclear Magnetic Resonance imaging apparatus includes at least two opposing magnetic pole pieces, which are located at a certain distance from each other and delimit an imaging region. The pole pieces are formed by at least one massive layer of a magnetically permeable material, and at least one layer of magnetically permeable material having a pack of superimposed sheets or foils, electrically insulated from each other. Each of the sheets has cuts arranged over the surface of the sheet in positions that are at least partly non coincident with the cuts of at least one, or both adjacent sheets. The magnetically permeable sheets or foils have a first face and a second face and the cuts are so arranged on each sheet that the cuts of a sheet or foil are offset and not coincident with respect to the cuts of an adjacent sheet or foil, when said adjacent sheet is laid over the previous sheet in an overturned position, i.e. with the first face turned toward the first face of the first sheet or with the second face of said adjacent sheet turned toward the second face of the first sheet.
