Problem Statement

The client desires an MR compatible model of the human hindbrain and upper cervical spinal canal to study how various dimensions affect cerebrospinal fluid flow (CSF flow) in terms of pressure against the spinal canal. Oscillatory flow is required in the model.

Last Week’s Goals

  • Write revised progress report including Gantt chart
  • Rework PDS to include additional specifications given by Dr. Haughton
  • Look at three designs (piece-wise, continuous tube, electrical) and decide which one will best solve the problem
  • Try to meet with Dr. Iskandar
  • Obtain dimensions of hindbrain and spinal canal

This Week’s Goals

  • Lauren – work on introduction of PDR
  • Mary – continue work with PDS and appendix of PDR
  • April – describe alternative solution #2 (continuous tube with blocks clamped on exterior to vary dimensions) for PDR
  • Tim – work on description for alternative solution #1 (continuous tube using pins to alter dimensions), write progress report
  • Team – compile reasons for selecting proposed solution (piece-wise model), put together rough draft of PDR

Summary of Accomplishments

  • Ruled out electrical design because nobody on the team has sufficient knowledge in this area
  • Mary – learned how to use the lathe and mill, which will be useful for the prototype of the proposed solution as it will require extensive machining
  • Evaluated the potential designs and decided to pursue the piece-wise model

Difficulties

  • We still have not received responses from two contacts concerning this project.

Activities

Team: Met in class to discuss potential designs and upcoming mid-semester presentation and report, brainstormed specifics of proposed design (changing pieces, preventing leaks, and pumping fluid)

Tim Eng: 2.0 hours – Wrote progress report with Gantt chart

Lauren Hensley: 1.5 hours – Started to gather background information for PDR

Mary Lim: 1.5 hours – Went to shop class to learn how to use the lathe and mill, worked on PDS summary

April Zehm: 1.5 hours – Worked on design drawings

Total time this week: 6.5 hours

Cumulative time: 42.75 hours
