Sorry, but imaging a living person with a "hacker" ultrasound scanner is asking for trouble. How can anyone be assured that this thing isn't transmitting too m

  This. Ultrasound is a great non-invasive medical imaging technique. The safety of medical imaging is well established: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2390856/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2390856/ ... PLEASE NOTE THE POWER LEVELS USED IN MEDICAL IMAGING APPLICATIONS: LESS THAN 720 mW/cm^2 (and possibly less for other types of imaging, this is just one study) that is milliwatts / cubic centimeter. It is VERY IMPORTANT to consider power delivery. Ultrasonic pulses are also a commonly used for lysing bacterial cells during protein purification -- essentially turning cells to mush. If, in your DIY project, you accidentally "turn it up to 11" (don't know the acutal power level threshold and do not want to find out) -- You could also turn your own cells to mush. Here is an example of ultrasonic cell preparation equipment (200 Watt range): http://www.hielscher.com/ultrasonic-lysis-cell-disruption-extraction.htm http://www.hielscher.com/ultrasonic-lysis-cell-disruption-ex... So. Please pay attention to the safety concerns of ultrasonic imaging, do all of your testing on fruit and use a high quality bench top regulated power supply.
