Tradename: CAT Scan Table
Company: Marconi (now Phillips)
  • We assisted Marconi ( now Phillips) with the design of this CAT scan table which had to comply with numerous aesthetic, ergonomic and functional requirements. This timeless design solution is the result of our investment in research and creative energy to arrive at an optimum design solution. Extensive human factors research was conducted by visiting clinics and testing models to maximize man-machine interface. Industrial design, human factors and creative engineering were synergistically integrated to arrive at a design which satisfied all the ambitious specifications for this medical device.

  • This front view of the CAT scan patient table clearly illustrates the minimal footprint occupied by the base and its visual relationship to the CAT scanner.

  • The table design was influenced by the canopy surrounding the CAT scanner as well as the needs of the patient and operator.

  • Extensive human factors studies were conducted to optimize patient interface and comfort based on technical limitations of the CAT scanner. Some of the considerations included patient girth, weight, and psychological effects associated with claustrophobia.

  • This stand alone image of the CAT scan table illustrates the application of color and form to critical features associated with user interface and operation. The three tiered base was designed with only two parts consisting of an aluminum extrusion and injection molded corners. Each wrap around tier was designed to collapse over the lower one allowing the table to change height.

  • Specially designed foam elastomeric polyurethane handles provided ease of operator interface with the table while allowing ease of patient transfer from a gurney. The self skinned foam handles proved to be highly durable, comfortable and aesthetically consistent with our overall design.

  • A completely integrated design resulted in classic design which proved to be successful and well received by patients as well as clinicians.

  • Phase 1 – Information Gathering and Product Specifications

    Before we attempted to design anything, our team conducted a comprehensive investigation into the overall product function including the mechanics and user interface. These photos depict the mechanical lift mechanism and relationship between the patient table and CAT scanner.

  • Our Phase 1 research and information gathering also included documentation of critical human factors considerations related to patient comfort and safety. Positions of the head, arms and legs were essential points of interest relative to patient safety.

  • Our on site visits to a few hospitals provided us with invaluable information pertaining to patient handling and care. These series of photos documented the process of patient transfer from a gurney to the CAT scan table. It emphasized the importance of minimizing any protrusions around the perimeter of the  table. Protrusions would increase the distance between the gurney and table, thus complicating patient transfer.

  • Phase 2 – Preliminary Concept Development

    The final design was selected from a number of preliminary concepts based on the same general design parameters established in Phase 1 of the project. This concept illustrates a multi-tiered collapsible table with curved nesting covers.

  • These concepts explored different patient pad designs as well as sculpted nested covers around the collapsing base.

  • We decided to explore more restrained concepts as depicted in these illustrations which eventually led to the final design concept shown in the following image.

  • Phase 3 – Concept Refinement & Foam Core Model

    These computer generated renderings illustrate the proposed design in relationship to the CAT scanner. The first image in the upper left shows the patient table in the parked position while the second image in the upper right shows the table in the fully extended position. A compressed configuration of the table/bed is shown in the lower image.

  • This full scale foam core model was constructed in sections and sent to our client for verification of size, appearance and general ergonomic considerations. Models such as this have always proven to be a cost and time effective method of communicating abstract ideas to clients.

  • This photo illustrates the position of the handle relative to a clinician and the overall size of the table.

  • Phase 4 – Details Production CAD Design and pre-Production Prototypes

    These images of a partially assembled pre-production prototype show different details of the table and verification tests performed with a dummy. The corner detail between the aluminum extrusions and injection molded joint clearly illustrates tight fit between these parts, creating a virtually seamless cover.

  • The prototype was eventually completely assembled with extruded aluminum panels designed to nest over one another with minimal clearance. The handle was actually cast from self skinning polyurethane foam over a steel insert for added structural integrity.
