ABSTRACT:
An ultrasound phantom and method of imaging are provided wherein the method quantifies data in decibels based on the log of a ratio of the signal intensity between adjacent regions within a ultrasound phantom such that the method can be used to quantitatively determine the imaging effectiveness of ultrasound devices at various depths by comparing quantitative data to a standard or absolute base. The phantom to be used with this method has multiple, regions which are characterized by an echogenic matrix and vertical, well-shaped sonolucent regions. The sonolucent regions are of the same shape and dimension and no sonolucent region shares the same axis. Ultrasound can be focused on one of the regions and the resulting ultrasound image quantifies the ability of the ultrasound to image regions existing at depths other than the depth of focus.
