Phased arrays for hyperthermia application have numerous advantages. They have the ability to be focused onto a desired location, and have a slightly greater depth of penetration than single applicators. Their most significant drawback has been the inability to determine the appropriate phasing necessary to focus onto a tumor location. This paper presents simulated results of a novel method, designed to overcome this problem. By precisely determining the appropriate phase coefficients and utilizing the conjugated, incoherent tumor emissions, the array can be noninvasively controlled and retro-focused onto the tumor.
用于热疗的相控阵有诸多优点。它们能够聚焦到期望的位置，并且与单个施源器相比具有略大的穿透深度。其最显著的缺点一直是无法确定聚焦到肿瘤位置所需的合适相位。本文展示了一种旨在克服此问题的新方法的模拟结果。通过精确确定合适的相位系数并利用共轭、非相干的肿瘤发射，相控阵可被无创控制并反向聚焦到肿瘤上。
