Combining the volume rendering and bicolour visualization techniques is proposed as an aid in interpreting single photon emission tomography (SPET) immunoscintigraphy (IS) recorded simultaneously with SPET bone landmarking (BL). The combination helps in localizing abnormal monoclonal uptake and in differentiating it from a physiological radioactivity distribution. The so-called rendered images (RIs) are obtained in both IS and BL studies according to a depth- weighted maximum activity projection algorithm. Fused BL and IS RIs are constructed by a simple, pixel by pixel addition. They are displayed using a bicolour grey-red scale, which makes it possible to visualize both studies by a transparency effect. This method was applied to patients suspected of suffering colorectal or ovarian cancer recurrences, in whom monoclonal antibodies against carcinoembryonic antigen, B72-3 or OC125 labelled with indium-111 were used.
有人提出将容积再现和双色可视化技术结合起来，以辅助解读与单光子发射断层扫描（SPET）骨定位（BL）同时记录的单光子发射断层扫描（SPET）免疫闪烁成像（IS）。这种结合有助于定位异常的单克隆摄取，并将其与生理性放射性分布区分开来。根据深度加权最大活性投影算法，在IS和BL研究中均可获得所谓的再现图像（RI）。通过简单的逐像素相加构建融合的BL和IS RI。使用双色灰红标度显示它们，这使得通过透明度效应可视化两项研究成为可能。该方法应用于疑似结直肠癌或卵巢癌复发的患者，这些患者使用了用铟-111标记的抗癌胚抗原、B72-3或OC125的单克隆抗体。
