Microwave phantoms for Craniotomy and bone defect monitoring
Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
To facilitate examination for osteogenesis and follow up after craniotomy similar head
models called phantoms are made. The head phantom should emulate the tissues
from a real head. This requires that the realistic head phantom have the same
electrical properties as relative permittivity (dielectric constant) and conductivity.
Both must be validated and matched for right frequency spectrum. Validation
measurements are performed by a coaxial slim probe connected to an Agilent
Technologies E8364B network analyzer. The range of frequency measured is from 1
to 50 GHz, but matching will only be processed for 1 to 10 GHz. The resonance
frequency for the antenna or sensor, which later will be used, is 2.4 GHz. The end
results of the head phantom consists of three different tissues or layers (skin, bone
and brain). Cavities will be created in the bone and will act as different defects or
stages of re-growing bone. Phantom cube is done for examining the influence of
implant in bone. Insertions of cube samples are made to emulate intermediates
between implant and bone.
