[A simple immersion test object for the evaluation of axial and lateral resolution of ultrasound pulse echo instruments].
We introduce a test object usable in a water tank for the determination of the axial and lateral resolution of ultrasonic pulse echo equipments. Measuring wires with a diameter of 0.2 mm form the bounds of a measuring line. The distance between the wires is infinitely variable during the test. This will make the smallest distance which can be resolved in the sonogram more accurately determinable than with the usual test objects with rigidly arranged rods.
