在典型的微创冷冻程序中，将多个冷冻探针插入组织中，目的是最大化预定目标区域内的冷冻损伤，同时最小化对周围组织的冷冻损伤。该研究小组最近开发了一种温控电加热器，以帮助限制对目标区域的冷冻损伤。这种新设备被称为“低温加热器”，它可以与任何冷冻外科冷却技术一起工作。该研究小组最近提出了一种原型计算机规划工具，有助于确定插入冷冻探针的最佳位置。该原型仅设计用于冷冻探针。规划过程利用了一种新的迭代优化技术，基于力场模拟。低温加热器与计算机化规划的结合是本报告的主题。目前的报告包括冷冻加热器的发展，并提出了一个改进的冷冻手术规划工具，包括冷冻加热器。
In a typical minimally invasive cryoprocedure, multiple cryoprobes are inserted into the tissue with the goal of maximizing cryoinjury within a predefined target region, while minimizing cryoinjury to the surrounding tissues. A temperature-controlled electrical heater has been developed recently by this research team, in order to assist in limiting the cryoinjury to the target region. The new device has been termed a 'cryoheater,' and it can work with any cryosurgical cooling technique. A prototype computerized planning tool has been presented recently by this research team, which helps to determine the best locations in which to insert the cryoprobes. This prototype was designed for cryoprobes only. The planning procedure utilized a novel iterative optimization technique, based on a force-field analogy. The combination of cryoheaters with computerized planning is the subject matter of this report. The current report includes a review of cryoheater development, and presents an improved cryosurgery planning tool which incorporates cryoheaters.
