外科手术越来越多地使用最小通路技术，这就产生了对可在此类干预期间使用的成像技术的需求。超声成像的优点是探头本身可以是介入性的。介入性超声探头必须足够小，才能进入手术部位，任何坚硬的部分都必须有长度限制，以允许足够的灵活性。在实践中，这意味着超声探头必须在高频下工作，并且已经产生了一组设计曲线，该设计曲线将线性和圆柱阵列配置的元件数量和超声频率与探头尺寸相关联。构建高频超小型探头带来了许多技术挑战，特别是与互连和封装有关的挑战。以直径1 mm的血管内探头的制造为例，讨论了这些挑战的解决方案。
The increasing use of minimal access techniques for surgery has produced a need for imaging technologies that can be used during such interventions. Ultrasound imaging has the advantage that the probe itself can be interventional. Interventional ultrasound probes must be sufficiently small to gain access to the surgical site, and any rigid portion must be limited in length to permit adequate flexibility. In practice this means the ultrasound probes have to operate at high frequencies, and a set of design curves have been produced which relate the number of elements and the ultrasound frequency to the probe dimensions for both linear and cylindrical array configurations. Constructing high-frequency sub-miniature probes presents a number of technical challenges, in particular relating to interconnects and packaging. Solutions to these challenges are discussed using the fabrication of a 1 mm diameter intravascular probe as an example.
