为了适应光照强度的变化，通常需要改变积分时间来选择合适的曝光量。
In order to adapt the variational light intensity, it is necessary to change integration time for optimal exposure.
因此，在临床应用上，应根据临床需要选择合适的扫描速度和辐射曝光量来获得大的消融率和小的热损伤。
In clinical applications, it is important to select appropriate scanning speed to obtain both high ablation rates and minimal thermal injury.
