Hope this answers some questions for some and I will keep on checking out the scene there and keep u informed.

Stay safe

of course it is possible. how do you guys believe that we are able to see our beautiful babies before they are born?
read on: (by the way, i studied this very subject while receiving my first physics degree)

"Ultrasound is widely used in health care for non-invasive diagnostics and in industry for non-destructive testing. It generates visual images from inside the test medium: the fetus, malignant tissue, stones, etc. in the human body. In the industrial applications, besides defect detection, ultrasound can also be used to determine significant materials characteristics such as density, thickness, mechanical properties, level sensing, and more. Knowledge of ultrasonically analyzed information is important for human health as well as for cost-effective production of quality industrial materials.
Ultrasound operates on the same principle as the other characterization methods also based upon wave- material interaction phenomena. These are: Optical, X-ray, infra-red, Raman spectroscopy, nuclear magnetic resonance, neutron, g-ray, mass spectrometry, etc. By propagating a wave in a given medium, useful information about the medium can be generated by analyzing the transmitted or reflected signals. Ultrasound differs from other wave-based methods because it does not require sample preparation; is non-hazardous; provides the means to determine mechanical properties, microstructure, imaging, & microscopy; is portable; and is cost-effective. Furthermore, ultrasound is applicable to all states of matter, with the exception of plasma and vacuum. Propagation of ultrasound in a material is not affected by its transparency or opacity. Table I provides a comprehensive introduction to ultrasound measurements and to the information revealed either directly or through correlation with measurements.

During the last twenty years, both ultrasound and its applications have grown phenomenally. Uses in industry have gone beyond overt defect detection in metals to include: characterization of elastic and mechanical properties; delaminations in multi-layered materials; proximity and dimensional analysis;
measurements of anisotropy and heterogeneity; surface profiling, chemical corrosion, crystallization and polymerization; liquid and gas flow metering; imaging of surface and internal features of materials; viscosity of liquids; texture and microstructure of granular and cellular materials; applied and residual stresses; high temperature, pressure, and radiation environment applications; robotics, artificial intelligence, and so on. These highly desirable applications of ultrasound have attracted the attention of a wide range of industries such as structural and electronic materials and components manufacturers, aircraft and aerospace, chemical and petroleum, plastics and composites, lumber and construction, highways and aircraft landing strips, bridges and railroads, rubber and tire, food, pharmaceutical, and on and on!"

"Scatterer sizes less than and equal to the wavelength
Consider a medium subjected to acoustic insonification, and a particle in this medium that is much smaller than the wavelength of the sound. If this particle is of the same density and compressibility as the medium, it scatters no sound at all. If its density is the same but its compressibility is different, it will react to the surrounding pressure variation by radially expanding and contracting differently than the surrounding medium. . The analytic solution for the radiation pattern from a spherical elastic scatterer in a fluid was first described by Faran[8]. The radiation pattern of such a scatterer is dependent on the material properties of the sphere and the medium and on the sphere's radius. Also, the result depends on whether one includes the effects of sound penetrating into the sphere and reverberating, which distinguishes the ``elastic'' from the ``inelastic'' solution."

peace,

Thanks for the follow-up bro.

Later,

msg, I do think we all know what ultrasound is doing in the world of medicine, but the question on the board was do they use it now a days for searching for drugs(gear, and other illegal drugs packed in vials and amps)

I loved the reading though and was highly informative. Thanks for that becuase there were things in there i didnt know.

Have a good one

Mav,

Losing the desire to hit the board, no problem. No desire to get laid, Boooooo! (just giving ya'shit man)

Yeah, and I'm going to let you borrow one of mine if you don't start gettin' some wood .

Later

hope this helps

the more you know...
the more you'll GROW!!!
