Sociedades dominantes de ecocardiografia lançam normas e recomendações para o 3D

Currently, 3DE matrix-array transducers are composed of nearly 3,000 piezoelectric elements with operating frequencies ranging from 2 to 4 MHz and from 5 to 7 MHz for transthoracic echocardiographic (TTE) and transesophageal echocardiographic (TEE) imaging, respectively. These piezoelectric elements are arranged in a matrix configuration within the transducer and require a large number of digital channels for these fully sampled elements to be connected. To reduce both power consumption and the size of the connecting cable, several miniaturized circuit boards are incorporated into the transducer, allowing partial beam-forming to be performed in the probe.

Acima, a explicação para o alto custo do transdutor 3D.
Processadores são inseridos no corpo do transdutor para diminuir o fluxo de sinais por cabo, o que reduz o diâmetro e peso dos cabos.

Agora só falta vender em quantidades elevadas para reduzir o custo unitário.
