TMMs or Phantoms

• Tissue Mimicking Materials (TMMs) or phantoms
  are materials that mimic some property of in vivo
  tissue of human body.
• Some applications of TMMs
• Training of medical students
• Medical imaging research
• Calibration of medical imaging systems

4
TMMs in Medical Imaging Research

• Problems with human subjects
• Ethical approval for any modification
• Getting enough subjects
• Hazards and liability
• Benefits of TMMs
• Flexibility in characteristics
• Simplification

5
Needs for and Aims of this Study(1)

• Needs Study of new medical imaging techniques at
  Control and Robotics Lab at the EECE of UBC
• Aims of literature survey
• Document different materials available
• Document the recipes
• Asses the state of the art in TMM
• Make comparative studies
• Summarize TMM characteristics in graphs and
  tables for ease of reference

6
Needs for and Aims of this Study(2)

• Emphasis
• Ultrasonography
• Sound speed
• Attenuation coefficient
• Elastography
• Density
• Elasticity
• Viscosity (if available)

7
TMM Ingredients
8
Comparison of Characteristics

• The classical literature review (summarization)
• \\rcl1\baghani\shared\Phantom_Survey
• Please see the tables in the handouts

9
Future Work

• Study two other materials
• Poly(vinyl) chloride or PVC
• Supersoft plastic which is also PVC based
• Figure out ways to graphically compare the
  characteristics

10
Thanks for Your Attention

• All suggestions welcome
• How can I best graphically compare the
  characteristics?
• Are there any other materials Im missing?
• What aspects have I overlooked?
