Created on: Tuesday, December 05, 2023
Photos of CoreNeedle biopsy training model prototyping process
  • Visual discrimination after biopsy sample extraction of lesion core (white) and lesion periphery (red)
  • Team CoreNeedle (left to right): Yiyi Yang, Celeste Wang, Shivani Kulkarni, Philip DuBose
  • Cross-section of benign lesion prototype. Red represents lesion periphery and white represents lesion core.
  • November 2023: Ultrasound image of benign lesion prototype. White/gray border represents the contrast between the lesion periphery and lesion core.
  • Low-fidelity proof-of-concept prototype of breast tissue: Skin Cast silicone with silicone spray additive. Current candidate for breast tissue prototype material.
  • CoreNeedle Team Logo
  • November 2023: Low-fidelity durability testing setup: hot plate set to 37C (98.6F) with open container of water for steam/humidity. Hot plate is covered during testing to lock in moisture and heat.
  • Malignant lesion prototype undergoing core needle biopsy sample extraction.
  • Labeled diagram showing the integrated CoreNeedle prototype interfacing with core needle device and Butterfly iQ+ portable ultrasound system.
  • Lesion sizes and design for CoreNeedle prototype. Lesion core is white pigmented silicone and is surrounded by a red/blue pigmented periphery that provides visual feedback after sample extraction.
  • Rendering of CoreNeedle breast tissue mold and dimensions. Roughly corresponds to an A-cup size breast.
  • Side-view rendering of CoreNeedle breast model exterior and dimensions.
  • Stacked-layers breast mold for CoreNeedle prototype. The layers facilitate replacement of lesions and replacement of sections of the model instead of the overall model to enhance reusability.
  • March 2024: Exterior appearance (right) and stacked layers with lesion pockets and inserted lesions (left) of CoreNeedle prototype. Modular design enables replacement of lesions and individual layers.
