MRISC Organizational Chart Medical Center Research and Graduate Studies Dr. Delwood Collins College of Medicine Dr. Jay Perman Director Dr. Charlie Smith Faculty Support MRISC Users Administrative Staff (Primary in Academic Depts) Officer Nancy Bailey Anders Andersen, Ph.D. Anatomy & Neurobiology Peter Hardy, Ph.D. Biomedical Engineering Radiology Technologist Agnes Bognar MR Physicist MR Postdoc David Powell, Ph.D. Liang Xuan, Ph.D.

  3. MRISC Staff and Faculty Peter Hardy Dave Powell Agnes Bognar Charlie Smith Peter Hardy Nancy Bailey

  4. Angry faces Happy faces (Blonder fMRI) Confrontation naming (Smith fMRI) N-back memory (Kelly fMRI) Finger Tapping (Young fMRI pre-op on 3T Trio) fl3d TSE hyperecho (Bada newborn on 3T Trio) Segmentation + perfusion (Pettigrew) MR elastography (Hardy) Bioabsorbable Screw (Johnson/Holtzhauer) A taste: Images from research collaborations Fiber Tracking Naming fMRI (RSNA 1995) Spectroscopy – tumor evaluation

  5. 1 Tesla Magnet B =I*N N = 6,000 windings 27km length Super conductor I = 300 Amps B Beware of Metal projectile Suffocate or Frostbite cryogens 1) Align protons

  6. Beware of Metal projectile SuperConducting Wires & Liquid Helium 1) Align protons

  7. Beware of Metal projectile Gradient Coil Vision 250 Amps 600 Volts 25 mT/m On even when not scanning (shimming) Electrocution (touch equipment) Conduction burns (wearing necklace) 2) Spatial location of protons

  8. Beware of Metal projectile Electrocution (touch equipment) Conduction Burns (wearing necklace) SAR Specific absorption rate (heating patient) Head Coil 3) Excite and Listen to protons

  9. Following slidesNot used

  10. After Protons are excited (pretend no T2) Simple Body Coil

  11. Electrocution (touch equipment) Conduction Burns (wearing necklace) Metal projectile Body Coil 2) Spatial location of protons
