Fillable “Derenzo” phantoms are used to characterize an imaging system’s resolution by measuring the FWHM of hole patterns with varying diameters and spacing. Holes within a size group are spaced at exactly 2D (twice the diameter) apart.
The fillable Derenzo phantoms feature six different hole sizes arranged in triangles around the center of phantom. These phantoms also feature our patented Linear-Filling Technology, which greatly reduces the volume required to fill the phantoms, ensures even filling (no bubbles), and reduces the radiation exposure to the handler of the phantom. This is all while improving image quality by reducing noise.
