Multimodal viewer

A method for viewing and manipulating a multi-channel image composed of several channels, whose channels originate from one or several imaging modalities, this method comprising the steps of:

• storing a multi-channel image in one or several 2D texture units, each representing a pack of four 8-bit tiles corresponding to one or several channels at a given location in the multi-channel image, each 2D texture unit being a fixed size memory storage unit in one graphics processing unit,
• taking a selection of one or several channels of the multichannel image into account,
• taking transformation and/or projection parameters for the selected channels into account,
• applying the transformation on the selected channels, according to received parameters, all pixels of the selected channels being transformed at the same time,
• projecting the selected channels into an RGB color space, according to the received parameters, all pixels of the selected channels being projected at the same time.

A system, for processing a multi-channel image, the multichannel image composed of several channels, the system comprising a server including:

• a conversion module for converting multi-channel images into one or several 2D texture units, each representing a pack of four 8-bit tiles corresponding to one or several channels at a given location in the multi-channel image, each 2D texture unit being a fixed size memory storage in one Graphics Processing Unit,
• a memory module for storing the obtained 2D texture units,
• a connection module for connecting one or several communication devices to a same account,
• a selection module for receiving the selection of one or several channels of a multi-channel image stored in the server, from any of the communication devices connected to the server at a same account,
• a setting module for receiving input transformation or projection parameters for the selected channels from any of the communication devices connected to the server at a same account,
• a processing module for instructing the devices connected to the server at a same account, to process—according to the received parameters—a transformation and a projection of the selected channels, into an RGB color space, directly in their Graphics Processing Units.
