Acoustic particle palpation for measuring tissue elasticity
Körük, Hasan; El Ghamrawy, Ahmed; Pouliopoulos, Antonios N; Choi, James J (American Institute of Physics, 2015)We propose acoustic particle palpation—the use of sound to press a population of acoustic particles against an interface—as a method for measuring the qualitative and quantitative mechanical properties of materials. We ... -
Acoustic streaming in a soft tissue microenvironment
El Ghamrawy, Ahmed; de Comtes, Florentina; Körük, Hasan; Mohammed, Ali; Jones, Julian R; Choi, James J (Elsevier, 2019)We demonstrated that sound can push fluid through a tissue-mimicking material. Although acousticstreaming in tissue has been proposed as a mechanism for biomedical ultrasound applications, such as neuromodu-lation and ... -
Displacement of a bubble by acoustic radiation force into a fluid-tissue interface
Körük, Hasan; Choi, James J (2018)Microbubbles in an ultrasound beam experience a primary Bjerknes force, which pushes the microbubbles against a fluid-tissue interface and deforms the tissue. This interaction has been used to measure tissue elasticity and ... -
The effects of ultrasound parameters and microbubble concentration on acoustic particle palpation
Saharkhiz, Niloufar; Körük, Hasan; Choi, James J (Acoustical Society of America, 2018)The elasticity of tissue—an indicator of disease progression—can be imaged by ultrasound elasticity imaging technologies. An acoustic particle palpation (APP) has recently been developed—the use of ultrasonically driven ...
