Doppler technology in this machine uses the sound waves to take images of what is inside your body. You then picture yourself in the guise of a superhero, sending out sounds that you cannot hear. As the machine emits high-frequency sound waves, it goes through our organs and tissues (a similar mechanism with how echo works when we shout in a large open area). The machine listens for the echoes and turns them into images on a screen after the sound waves bounce back. It is a very safe technology as there are no radiations being exposed (like X-rays that can be deleterious in large quantities).
Pozitivno pri ultrazvočnem dopplerskem skeniranju je, da ni tako invaziven. To pomeni, da lahko zdravniki vidijo notranjost vašega telesa, ne da bi vas rezali ali zbadali v kožo. Zdi se, kot da bi gledali noter od zunaj, namesto da bi razbili vrata! Zaradi tega je varen in neboleč način za pregled številnih različnih zdravstvenih stanj brez vpletenega nelagodja. Zdravnikom omogoča tudi, da vidijo pretok krvi, ko se dogaja. To nam zelo pomaga pri prepoznavanju bolezni, zaradi katerih je naša kri nagnjena k slabemu pretoku, kot so globoka venska tromboza (ki vključuje nastanek strdkov v venah) in krčne žile; nekatere otekle vijolične ali modrikaste žile, ki postanejo vidne skozi kožo.
