混合紧凑型伽马相机（HCGC）是一种便携式光学伽马混合成像仪，设计用于术中医学成像，特别是前哨淋巴结活检程序。为了研究HCGC在淋巴系统成像中的能力，我们设计并制作了两个淋巴造影模型。这些模型允许定量评估和评价HCGC的淋巴管（LV）和前哨淋巴结（SLN）检测。融合光学和伽马图像显示两种模式的良好对齐，允许LV和SLN内的活动定位。在10 cm的成像距离处，在模拟LV的检测过程期间，HCGC的空间分辨率在大于1.5 cm的间隔处没有降低（变化
The Hybrid Compact Gamma Camera (HCGC) is a portable optical-gamma hybrid imager designed for intraoperative medical imaging, particularly for sentinel lymph node biopsy procedures. To investigate the capability of the HCGC in lymphatic system imaging, two lymphoscintigraphic phantoms have been designed and constructed. These phantoms allowed quantitative assessment and evaluation of the HCGC for lymphatic vessel (LV) and sentinel lymph node (SLN) detection. Fused optical and gamma images showed good alignment of the two modalities allowing localisation of activity within the LV and the SLN. At an imaging distance of 10 cm, the spatial resolution of the HCGC during the detection process of the simulated LV was not degraded at a separation of more than 1.5 cm (variation
