My work at Landspitali
Main activity at LSHBIOMODELING service: The creation of highly accurate physical models of human anatomy directly from medical scan data
Clinical Applications
• Diagnostic: supporting pathologist with visualization of difficult anatomical case
• Planning surgery in complicate orthopaedic and maxilla facial operation
• Patient follow up in craniofacial trauma, studying structural changes in bone and soft tissue
• Patient compliance providing computer simulating in maxilla lengthening
• Prosthesis design
Prosthesis Design: Foot Amputation
Main service: Planning and Simulation in Mandibular Lengthening

Contraction activities induce Bone remodeling
Periprosthetic hip fracture risk analysis
The project aim to develop a computational procedure based on 3D modelling and finite
element analysis for evaluating periprosthetic femur fracture risk and to find optimum
selection methods for different hip prosthetic types
CEMENTED TOTAL HIP REPLACEMENTS
the surgeon uses bone cement for fixation of the prosthesis to the skeleton
CEMENTLESS TOTAL HIP REPLACEMENTS
the surgeon impacts the total hip directly into the bed prepared in the skeleton
How do stress distribute along bones in the two implant techniques?

Inner ear morphology fin whale vs. human
• Information from the inner ear is important in hearing and maintaining balance through postural control.
• As aquatic mammals whales have suffered from seasickness during their evolution.
• Morphological study of their inner ear might cast light upon their adaptive solutions of this disturbing phenomena

Benign Paroxysmal Positional Vertigo
BPPV is a common cause of dizziness. A recent study showed that 9% of people have BPPV, in most cases undiagnosed.
Project aim: Research and develop a monitoring technique to quantify morphological changes occurring in patient's inner ear suffering from "benign paroxysmal positional vertigo".
Project development and Methods
A: 3dimensional model of human inner ear. B: posterior semicircular canal cross sectional area (coloured in blue) crossed by a profile line (coloured with cyan). C: Density profile within the semicircular cross sectional area (y: HU values, x: distance in mm).
FEA of Electric fields in the brain
• We develop high ( 0.5 to 1.0 mm) resolution human head models from segmented MR images.
• These models have detailed 3-d representation of major tissue surfaces.
• We use these models to predict the electrical and magnetic activity of human brain under normal and epileptic conditions.
• In addition, we also analyze the high density (256 to 305 channel) EEG and MEG (magnetoencephalogram) data to noninvasively localize the epileptogenic areas in the human brain.
Segmentation
• Distinguish different tissues
• Extract gray matter/white matter boundary
Computations
• Extract normal vectors from gray/white matter boundary
• Place electric sources where the normal vectors are – Representing the
pyramidal neurons in the cortex
• Simulate E-fields
