Fabrication and Characterization of a Miniaturized 15-MHz Side-Looking Phased-Array Transducer Catheter (PDF)
This paper describes the development of a miniaturized 15-MHz side-looking phased-array transducer catheter.
This paper discusses the challenges with manufacturing low capacitance micro-coaxial cable that uses cellular (foamed) insulation as a dielectric and improvements that can be made in order to achieve even finer gauges for diameters previously not achievable.
Development of the Medical Internet of Things. Hitachi’s Approach to Transformation Through IoT Innovation
Ultrasound medical devices typically employ multiple fine wire gauge cables. There are many aspects to a cable design that can impact cost, but one in particular—color—can have a significant effect on the overall budget.
Managing the thermal impact on advanced medical cable assemblies through novel cable construction techniques and materials (PDF)
Thermal management inside medical cables and devices is becoming increasingly challenging for complex, next generation products. The trend for lighter, smaller and more flexible ultrasound probe solutions built with fine wire, ultra-high density coaxial cable is creating new and unique challenges. Many of the conventional approaches with regards to materials and construction are no longer adequate when reliability and usability are paramount.
Ultrasound probe cable must efficiently dissipate the heat of piezoelectric elements in a probe head. We evaluated the heat transfer by measuring thermal resistance with various conditions. By simply changing the braid shielding material inside the cable and by implementing a thermal connection method to the heat source, we found that at least 40% of the heat could be efficiently transferred to the cable.
A microcoaxial cable was implemented into a miniature imaging sensor probe. June 2009 More ...
