    Hello,

    We are studing the viability of develop an ultrasound equipment for
    medical ecography applications, using low cost components.

    The equipment will have modest targets: 3.5 MHz, resolution of 4 bits,
    ....

    The first impressions (?) are that more or less all the main components
    (screen, image processing, A/D, preamplifier, ... ) are not key
    problems, taken into account the frequencies, amounts of data, ... to
    be handled. The big exception seems to be the actuator/sensor to be
    used in the probe (a PZT array ?).

    It has been imposible to find any company who sales this kind of
    elements. The most near we have found is a non-array 2x2 cm block of
    3.5 Mhz PZTs (at http://www.smart-material.com, section products). But
    it is not an array, thus, the screening should be mechanical (?).

    Please, has someone some advice, or pointer? State of art, providers,
    .... any thing is welcome.

    Thanks a lot.

    PS: Of course, another history is to obtain the quality certifications,
    ....

    Next time I suggest to try Google first:

    http://www.google.com/search?as_q=&...as_dt=i&as_sitesearch=&as_rights=&safe=images

    That brings up many of the suppliers.

    If you just want one or two be prepared to shell out some serious money.
    BTW, most ultrasound manufacturers build their own transducer arrays and
    that fabrication procedure is a closely guarded secret. They won't tell you.

    Huh?

    What planet have you been living on for the last 10 or 20 years?

    Pick a topic - heck, make something _up_ - and there's a NG for it. ;-)

    Cheers!

    Hello Rich,

    Well, yeah, but most of the time I found a newsgroup it turned out it's
    nearly dead or dormant. Even popular topics such as home repair have NGs
    but nothing that comes even close to s.e.d. There I found better forums
    such as plumbing groups on regular web sites.
