Abstract [en]

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.

Keywords: agar, BMP, body morphogenetic protein, bone implant, brain phantom,

craniosynostosis, craniotomy, cube phantom, phantom, re-growing bone, skin

phantom, skull phantom, tissue.
