Main activity at LSHBIOMODELING service: The creation of highly accurate physical models of human anatomy directly from medical scan data

Page 13: Student exchange and Cooperation between Federico II and Reykjavik Universities Biomedical engineering program Paolo Gargiulo, PhD.

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

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

Page 24: Student exchange and Cooperation between Federico II and Reykjavik Universities Biomedical engineering program Paolo Gargiulo, PhD.

CEMENTLESS TOTAL HIP REPLACEMENTS

the surgeon impacts the total hip directly into the bed prepared in the skeleton

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

Page 35: Student exchange and Cooperation between Federico II and Reykjavik Universities Biomedical engineering program Paolo Gargiulo, PhD.

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
