Ultrasound of obese patients does not produce clearer image results as compared to that of patients with normal Body Mass Index (BMI). This is because the fat molecules are tightly packed and do not leave much space for anything to pass through. The aim of our study is to tackle this fat temporarily via External Ultrasound Assisted Liposuction (XUAL) technique and make room for ultrasound waves to pass as much as possible. An ultrasound signal was fed to 3 different types of medium having the properties of: soft tissue, solid human body fat, and liquefied fat. The signal strength in fat decreases considerably throughout the wave propagation as compared to soft tissue. Whereas in liquefied fat, the signal strength does not reduce to such level rather it resembles to soft tissue. Thus it was shown virtually that when, practically, a transducer probe with both the ultrasound and XUAL properties will be made, it will yield better results for high BMI patients.

Abstract


Ultrasound of obese patients does not produce clearer image results as compared to that of patients with normal Body Mass Index (BMI). This is because the fat molecules are tightly packed and do not leave much space for anything to pass through. The aim of our study is to tackle this fat temporarily via External Ultrasound Assisted Liposuction (XUAL) technique and make room for ultrasound waves to pass as much as possible. An ultrasound signal was fed to 3 different types of medium having the properties of: soft tissue, solid human body fat, and liquefied fat. The signal strength in fat decreases considerably throughout the wave propagation as compared to soft tissue. Whereas in liquefied fat, the signal strength does not reduce to such level rather it resembles to soft tissue. Thus it was shown virtually that when, practically, a transducer probe with both the ultrasound and XUAL properties will be made, it will yield better results for high BMI patients.
