PTA's participation with Siemens began early in the development of the product with design, material selection and metal conversion discussions.

Siemens is a leading worldwide manufacturer and service provider of diagnostic medical ultrasound systems that generate, display, archive and retrieve ultrasound images.The Aspen™ and Sequoia™ Systems combine superior image resolution with enhancements for improved performance. The units feature compact systems with multi wheel swivel control, height adjustable keyboards, and tilt-and-swivel monitors.

• Plastics allowed Siemens to package electronic, mechanical, optical, and consumable functions within advanced ergonomic designs at an acceptable price point.
• PTA recommended that aluminum molds be used for tooling — the most cost-effective method for limited volume runs of several large sections, such as panels and fascia.
• To achieve the rigidity required over large areas, PTA suggested that many of the plastic parts be manufactured from the structural foams Lexan and Noryl. ( view 2 )
• Final assembly included painting the parts to match the color and texture of nearby sheet metal and injection-molded components. In addition, PTA shipped complete kits ensuring cost-effective manufacturing at Siemens.
