The Peira TM900 handheld tumor measurement instrument

Traditionally and since the start of their use in oncology research, the volume growth of xenografts or subcutaneous tumors in small rodents has been monitored by using a traditional mechanical caliper. Technological evolution and the increase in computing power have facilitated the development of new devices such as the Peira TM900, . It is a lightweight handheld instrument that makes a direct 3D measurement of the tumor volume by acquiring a stereoscopic image and reconstructing the 3D shape of the tumor. This allows a direct 3D capture of the volume. A tumor image, its 3D shape and all geometrical data are automatically calculated and stored. Database, data management and processing software are included. The system can be complemented with a weight scale.
