The lung insert contains nodules of different sizes, shapes and different densities.
The phantom is designed to assess the detectability of all kinds of lung nodules within the lung region.
It houses multiple spherical nodules of different densities and dimensions arranged randomly within both lung lobes. The nodules are designed to cover various imaging scenarios with respect to nodule type and grey value (e.g. ground glass opacity). The enclosed lung material consists of homogeneous and heterogeneous lung granulate, which can be optionally filled into the lung lobes by the enduser.
In order to mimic a (semi-)anthropomorphic surrounding it contains a bone-like spine (corticalis and spongiosa). The body is made of soft tissue-equivalent material.
The QRM-20114 is a compact functional phantom and can be easily positioned on the patient couch.
