abstract = "This paper presents an extension of vibro-acoustography imaging
technique. The standard technique relies on the single-frequency
dynamic radiation force (or stress) produced by a highly focused
dual-frequency ultrasound beam. We propose a multifrequency
vibro-acoustography method based on the radiation stress generated
by a beam with multiple frequencies. The system point-spread
function (PSF) is obtained in terms of the acoustic emission by a
point-target in response to the employed radiation stress. The PSF
is evaluated for an eight- and a sixteen-element sector array
transducers. Three phantom images are used to show how the system
transforms them into observed data. Considering only visual
criteria such as contrast and resolution, simulations show the
sixteen-element sector transducer renders better images.",
