Novel statistical model devised for ultrasonography errors

"Current ultrasonic scatterer size estimation methods assume that acoustic propagation is free of distortion due to large-scale variations in medium attenuation and sound speed," scientists in the United States explained. "However, it has been demonstrated that under certain conditions in medical applications, medium inhomogeneities can cause significant field aberrations that lead to B-mode image artifacts."

"These same aberrations may be responsible for errors in size estimates and parametric images of scatterer size," according to A. Gerig and colleagues at the...
