Initial prototyping has begun
Ordered caliper to be modified for prototype
Sleeve to hold transducer has been designed
Accomplishments from Previous Week
Designed a sleeve for the caliper to hold transducers
Ordered and received a caliper for initial prototyping
Identified risks: misalignment of transducers, optimizing spring stiffness
Came up with potential solutions to the identified risks
Outlined and began the risk reduction presentation
Met with sponsor to see a phantom firsthand and discuss project specifics
Goals for Next Week
Finish risk reduction presentation (all)
Further discuss solutions for the spring component (all)
3D print transducer sleeve for caliper (Dan)
Setup MAE 156B website (Andy)
Order transducers (Anuj)
Check in with Tom regarding budget allotment (Anuj)
Confirm sponsor meeting for next week (Ahmed)
Cut caliper down to prototype size (Ahmed)
Sponsor Comments / Actions Taken - Meeting on 3/9/16 at Moore’s Cancer Center
Calipers need to have a spring-like mechanism to bounce back to 10cm width once the measurement is done (after every squeeze).
Action: Currently devising solutions individually to be discussed together and finalized by the end of next week.
Transducer sleeve needs to be doubled from caliper arm length to account for size of breast
Action: Dimension this into CAD part before 3D printing
Transducer sleeves can have 1-2 mm misalignment tolerance approximately
Action: To be considered after results of initial prototyping
Order 1KHz ultrasound transducer that is 6 mm maximum and 3 mm minimum in width
Action: To be considered when ordering transducers
Instructor Comments / Actions Taken
Identify if sponsor has phantoms to work with
Action: Verified that sponsor does indeed have phantoms
Risks and Areas of Concern
Spring mechanism affecting the reading while still performing its function
Misalignment of the caliper arms due to small size
