MRI-Compatible Cart Table

Converted preliminary sketches into a complete parametric table assembly and supported adaptation for a hospital MRI system.

YEAR
2026
STATUS
In Development

Objective

Develop a detailed, manufacturable equine MRI table assembly from incomplete legacy sketches, photos, notes, and measurements while preserving compatibility with existing veterinary equipment and adapting the platform for a Siemens MAGNETOM Free.Max MRI installation.

Requirements & Constraints

  • Support an equine patient load of up to 2,500 lb.
  • Maintain compatibility with the existing MRI cart architecture and fabrication methods.
  • Fit over and around the Siemens MRI patient bed without interference.
  • Preserve adequate clearance relative to the MRI bore and surrounding equipment.
  • Create a removable support extension capable of supporting the weight of a horse’s leg and hip region.
  • Ensure the support extension fits within the available MRI bore envelope.
  • Design components around practical fabrication, assembly, and installation constraints.

Engineering Work

  • Reconstructed the existing MRI cart from photographs, loose notes, measurements, and legacy product information into a fully defined Fusion 360 assembly.
  • Created new components and production drawings while updating legacy parts and assemblies to reflect current fabricated configurations.
  • Modified the cart geometry for compatibility with the Siemens MAGNETOM Free.Max, accounting for MRI bed geometry, equipment clearances, and tabletop positioning.
  • Designed a side-mounted swivel support attachment that interfaces with the tabletop and extends into the MRI bore to support portions of the horse during imaging.
  • Coordinated directly with fabricators to verify dimensions, assembly sequence, manufacturing details, and discrepancies between documentation and the physical product.
  • Performed preliminary static structural analysis in Fusion 360 to evaluate stress concentrations and deformation trends in the cart and support attachment.

Outcome

The project transformed incomplete and fragmented product information into a controlled digital CAD assembly that could support future design revisions, manufacturing drawings, and assembly documentation. The Siemens-specific redesign established a geometry compatible with the MRI system while incorporating a new support attachment designed around structural and bore-clearance requirements.

The work also improved the company’s engineering documentation by correcting legacy CAD discrepancies and capturing fabrication and assembly knowledge that had previously existed primarily through shop-floor experience.

Key Learning

This internship project gave me experience working from incomplete real-world design information rather than a predefined engineering specification. Reconstructing the existing table required interpreting photographs and measurements, resolving inconsistencies, and working directly with fabricators to determine how the product was actually manufactured.

The Siemens modification reinforced the importance of interface-driven mechanical design. Structural performance was only one part of the problem; the table and support attachment also had to operate within fixed MRI geometry, tight clearance constraints, existing product architecture, and practical manufacturing requirements.
