| | Ultrasound - Wikipedia, the free encyclopedia |
 | | The basic principle is that an ultrasonic pulse is generated in a particular direction. | | | Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique used to visualize muscles and internal organs, their size, structure and any pathological lesions, making them useful for scanning the organs. | | | Bats use a variety of ultrasonic ranging (echolocation) to detect their prey. |

| | ULTRASONIC LIPOSUCTION |
| | The external ultrasonic liposuction device is similar to the hand-held devices used to treat deeper tissues such as muscle and fibrous tissues in physical therapy. | | | Ultrasonic liposuction is not really a very new technique. | | | Additionally, the gels and creams used to allow the external ultrasonic device to pass over the skin smoothly could possible cause an allergy and can be introduced internally through the entrance wounds (in small amounts) when cannulae pass through the wounds into the patient. |

| | Ultrasonic Liposuction |
| | Ultrasonic liposuction is a new advance in body contouring surgery that allows the surgeon more latitude in removing unwanted body fat. | | | Ultrasonic liposuction is not a replacement for traditional liposuction, but it is an addition. | | | It allows the surgeon to remove more fat from areas in the body that were difficult to treat with traditional liposuction. |

| | Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. | | | In addition, clamp-on transducers can be used to measure flow without regard to materials of construction, corrosion, and abrasion issues. | | | This flowmeter does not obstruct flow so it can be applied to sanitary, corrosive and abrasive liquids. |

| | ultrasonic liposuction compared with traditional liposuction |
| | Some studies also suggest that with ultrasonic liposuction there is less pain and discomfort. | | | Because there is less damage to the small blood vessels, patients experience less bruising and perhaps less irregularity with ultrasonic liposuction.Patients may be happier because the results are seen earlier, usually weeks instead of months after surgery. | | | In the early stages and with the two stage method of ultrasonic liposuction the process may take longer. |

| | This becomes especially so for first-time users, since they may not have a backlog of past experience to guide them in setting up the process. | | | Ultrasonic welding is based on acoustic and solid-state phenomena, and not fusion phenomena, so users may not make sufficient effort to acquaint themselves with this "animal." Assuring set-up of a good, robust set of welding procedures is very important. | | | Ultrasonic plastic welding is based on melting and fusion of the material (in a sense, like many metal welding processes, such as arc, resistance or laser), but at much, much lower temperatures than experienced in metal fusion processes. |
