![]() ![]() Pulse width (-6 dB) 16.6 – 480 ns, with steps of a 6 ns.Specifications: US-key Pulser/Receiver board (Lecoeur Electronique): US-key can be operated in both, Pulse echo and through transmission modes. Thus, it is in use for portable solutions and quick tests on the laboratory. US-Key is small sized pulser-receiver controlled via USB interface. ![]() Sampling frequency of 250 MHz and resolution of 8 bits using a digital oscilloscope (LeCroy Corporation, Wave Runner 6051A, Chestnut Ridge, NY, USA).Intra Vascular Ultrasound – IVUSĪ clinical high frequency intravascular ultrasound (IVUS) device (ClearView Ultra, Boston Scientific Corporation, San Jose, CA, USA), equipped with an 9 and 40 MHz ultrasound catheters enables ultrasound imaging and determination of reflection and backscattering parameters. LabVIEW controlled pulser and receiver parametersĪDQ 112 Analog-to-Digital converter board (SP Devices):įig 1.Specifications: DPR500 Dual pulser/Receiver board (JSR Ultrasonics): Liquid filled measurement tanks are temperature controlled and can be manually adjusted to obtain perfect alignment between the transducer and the sample. For smoother and more precise scanning, SAM equipment is placed on a custom built vibration isolated table with a mass equal to a big Harley Davidson. The scanning area in x-y direction is 300 mm and in z direction 50 mm (Zaber). Pulser-Receiver can be used for pulse-echo and through-transmission measurements. TicoTico can drive ultrasound transducers with centre frequency roughly up till 350 MHz (beam diameter at focus ~ 4 µm). Scanning acoustic microscope TicoTico enables ultrasonic measurements over a wide frequency range. ![]()
