The purpose of this study is to design a water calorimeter with three goals in mind: (a) To be fully magnetic resonance (MR)‐compatible; (b) To be imaged using kV cone beam computed tomography (CBCT), MV portal imaging or MRI for accurate positioning; (c) To accommodate both vertical and horizontal beam incidence, as well as volumetric deliveries or Gamma Knife®. Following this, the calorimeter performance will be measured using an accelerator‐based high‐energy photon beam.

便携式可成像MR兼容水热量计的第一阶段验证。

这项研究的目的是设计一个水量计，其考虑了三个目标：（a）与磁共振（MR）完全兼容；（b）使用kV锥形束计算机断层扫描（CBCT），中压门静脉成像或MRI进行成像以准确定位；（c）适应垂直和水平光束入射以及体积传递或GammaKnife®。此后，将使用基于加速器的高能光子束测量量热仪的性能。
