CTP103 CT low contrast performance detection phantom

CTLow Contrast Modules: A range of various diameters and12composed of contrasting cylindrical rods

Used to measure low contrast performance.40mmlong pole at allzprovides consistent contrast values at all axis positions,

This avoids any volume averaging errors when scanning sections. Unique secondary test objects enable evaluation of different scanning protocols

(pitch, slice width and reconstruction algorithm) effectiveness in parsing sub-object low contrast objects. For the selection of spiral and multi-slice imaging protocols, a unique sub-low contrast target (truncated cylinder) has been included in this module. Comparing images obtained by scanning sub-objectives with different imaging settings (slice width, spacing and reconstruction algorithms) provides valuable information,

To help select the best protocol for identifying small contrast objects such as tumors. All sample and background materials have comparable effective atomic numbers; only changes in density produce changes in the effective attenuation coefficient. . For each of these lengths, have a diameter of13mmgoal。
