A three-dimensional reconstruction of metastatic adenocarcinoma in lymph node

Lymph nodes are a common site of metastatic cancer. The ability to view the three-dimensional configuration of complex biological structures, rendered in solid model form, might help to further elucidate the pathophysiology of metastatic disease. This paper presents a method for three-dimensional reconstruction from serial sections of a lymph node containing metastatic adenocarcinoma. The reconstruction and subsequent animation were carried out using the P3D graphics software (developed at the Pittsburgh Supercomputing Center) and rendered by the Dore high-speed renderer on an Ardent Titan graphics workstation. As different views of the model were produced, they were recorded a frame at a time on U-matic video tape. A three-dimensional solid-modeled object portrays metastatic, neoplastic elements within a lymph node.
