Abstract: A medical collaboration system for pre-operative collaborative assessment includes an imaging center, a data center, a DICOM storage, at least one displaying means, an API and a rendering device. The data center includes a cloud storage, a user database, a DICOM converter and a web interface; the cloud storage includes a 3D medical volume storage; the imaging center is connected to the data center. The API is connected to the data center, the at least one displaying means, the rendering device and the 3D medical volume storage. The DICOM storage is connected to the DICOM converter and the DICOM storage is configured to send the 2D medical records to the DICOM converter. The DICOM converter is configured to remove confidential metadata from the 2D medical records, convert the 2D medical records into 3D medical volumes, and send the 3D medical volumes to the 3D medical volume storage for storing.

Abstract: The present invention relates to a virtual reality simulator (10) for small laboratory animals (100), in particular rodents, which comprises a head clamping mechanism (20) for securing the laboratory animal (100) and virtual reality glasses (40) with two wings (30), each of the wings (30) having a display (34) and a lens system (36) spaced therefrom and connected together by a light barrier cover (32), and the virtual reality glasses (40) are configured to allow the two wings (30) to align with each of the eyes (101) of the laboratory animal (100), respectively. The invention further relates to a method applying such a simulator (10).
