Ultrasound Transducer Simulation Page
BioSono provides a cyberspace (www.biosono.com) where researchers, engineers, and students can find useful reference and educational materials, conduct acoustic simulation, post questions on design and development, and get answers. The online KLM based transducer acoustic stack simulation, which is currently free, can help you choose piezoelectric, matching and backing material, and a tuning electrical network. The output from the model includes electrical transmit impedance, acoustic receive impedance, and the impulse or pulse-echo response. The ultrasound beam profile simulation provides the calculated transmitted ultrasound pressure field under certain excitation for a given transducer aperture in a number of different geometrical configurations, including circular elements (flat and concave piston), rectangular elements, linear arrays, convex arrays, and 2D arrays. The simulation is based on Field II, which is a free program that utilizes the spatial impulse response method, and has been validated by many researchers for accuracy. In addition to the web based acoustic simulation, we also provide pulse-echo system, transducers, and customized design and develop services.

Imaging Applications engineer:

Looking for an experienced applications engineer to contribute to the growth and success of the imaging product line. Products primarily include analog front ends for ultrasound systems, but can be expanded to cover other imaging modalities such as MRI, PET and CT. The dynamic environment requires a high level of motivation, commitment and flexibility from the applications engineer. This position will require candidates to lead applications efforts from initial Si bring up to ramping customers developing high performance imaging systems. Responsibilities will also include development of evaluation modules (board design) detailed lab measurements.


1) Education: Masters. Candidates with Bachelors degrees will also be considered with relevant work experience.

2) Work experience: Greater than 3 years for people with Masters degree. Greater than 5 years for people with Bachelors degrees.

a) Analog: Excellent knowledge of analog systems, related measurement techniques and board design. ADC and signal conditioning experience a must.

b) System: Familiarity with system level concepts and interaction between analog and digital subsystems.

c) Teamwork: Ability to work closely with a fast moving team in different capacities is a must. The job also requires flexibility and in terms of tasks performed: design, lab characterization, customer support.

d) A proven record/ability to Design IN products with good customer facing skills
