Together we are dedicatedto high quality and cost-effective materials production andapplications through Ultrasonic Non-DestructiveCharacterization. Ultran accomplishes this by focusing onthe heart of ultrasound: the ago we realized that for ultrasound to rival otherwave-based methods, we had to first develop the acoustic characteristics are needed to achieve thedesired materials test objectives.

3 Proper techniques areessential to the test environment and the condition of amaterial. These goals are possible only throughtransducers with the right acoustics that perform undergiven conditions of years of non-stop R&D in Transducers and appli-cations allows us to share Ultran s milestones with SERVICESThis is beneficial for establishing a strategy for assessing riskfactors and cultivating a problem-solving mode. R&D projectsinclude non- destructive characterization of special materialsand processes, novel transducer designs, and other diagnosticor non-diagnostic uses of keep you up-to-date with the progress of your project. Oncompletion of a project we give you a technical reportdescribing objectives, techniques, observations, conclusions,and recommendations. As you would expect, science andtechnology transfer -- including education, training, andconsultancy -- becomes an extremely significant part of are dedicated to exceedingthe expectations of our has achieved an authoritative position in the ultrasonicindustry by continually introducing innovative solutions to verycomplex problems.

Charles A. Nielson, Senior Sensor SpecialistDow Chemical In many instances we discussed at length myproblems and you were extremely free with youradvice and comments, which I recognized as havingdeep foundations in both theory and practicalexperience. Julius Frankel, Senior Department of Army The help which Ultran provided for atheroscleroticplaque dissolution and to me is very typical of thework and support they give to their many clients andfriends. It would be difficult to imagine a client notbecoming Ultran s friend.

10 Joie P. Jones, ProfessorDepartment of Radiology, UC, Irvine, CA Ultran has routinely been contacted by my officefor support and consultations. Rarely have I had theopportunity to work with individuals like those ofUltran. Their goals, expectations of themselves, andhigh standards for delivering a quality product havealways exceeded what is anticipated. Paul Karner, Former Principal EngineerThiokol Propulsion I especially admire Mahesh for his entrepreneuer-ship in building a company, namely UltranLaboratories, Inc., based on his own excellentresearch and in part on the needs of NASA andaerospace industry. Alex Vary, retired Chief NDE BranchNASA TO ULTRASOUND, ULTRAN S Transducers & to UltrasoundIt is now well established that by propagating ultrasound in agiven medium, useful information about the medium can begenerated by analyzing the transmitted signals. This isanalogous to all other methods of characterization andanalysis also founded upon wave-material interactionphenomena.
