Ultrasound Probe

Posted: 2018-06-14 16:56

                                               The use of an ultrasound, also called a sonogram, in medicine for diagnosis and preventive care has been common for decades. One limitation of

                                               traditional ultrasound images is that they are mostly only available as low-contrast, grayscale images. Color ultrasound represents a new development

                                               that uses collected data to add color to the image, both increasing contrast and making the image easier to interpret. Despite the way it sounds,

                                               color ultrasound does not depict the actual color of the area of the body being imaged, but rather assigns colors to certain detected patterns, in

                                               order to make them stand out from the rest of the image.

                                               An ultrasound probe, also known as a transducer, is a medical diagnostic device that emits ultrasound waves into a patient's body and transmits data

                                               to a computer to produce an internal image of the body, known as a sonogram. Ultrasound waves bounce off of tissue masses and boundaries in

                                               the body, and these echoes are recorded by the ultrasound probe and interpreted by the computer, which then creates the sonogram on a monitor.

                                               The ultrasound probe is generally placed directly on the patient's body and moved over the area to be viewed. Since water is a good conductor for

                                               sound waves, a water-based gel is usually placed on the patient's skin to help facilitate movement of the ultrasound waves, and patients undergoing

                                               obstetric ultrasound are usually asked to arrive for the test with a full bladder.

                                               A Doppler probe is a device most often used in medical applications to measure the shift in sound waves emitted by and bounced back to the device.

                                               The probe allows the measurement and either visualization or audio simulation of the movement of substances within the body. Doppler probes are

                                               most often used in cardiovascular applications, and for confirming and monitoring pregnancy in both humans and animals.

                                               The acronym "LIDAR" stands for light detection and ranging. Where radar uses radio waves to determine an object’s range or distance, LIDAR uses

                                               light in the form of a laser for a variety of measurements. Using either pulsating or continuous laser beams to measure the changes in light frequency

                                               and other factors, LIDAR laser technology serves in a variety of applications. Specifically, Doppler LIDAR measures wind speed with both pulsing and

                                               continuous laser beams.

                                               Power Doppler is a highly sensitive medical test that detects the flow of blood through arteries. During a Doppler ultrasound, a specific area of the body

                                               is covered in a special Doppler gel, and an instrument called a transducer is placed over the area. Sound waves are sent into the body and are deflected

                                               off organs and blood cells, and they are then picked up by a microphone and sent to a computer for analysis.
