A docking station for use in combined imaging of a tissue wound and a test substrate comprising a sample from a tissue wound, the docking station comprises means for connecting the station to a processor which processes and stores the images. The docking station also incorporates means for receiving a test substrate comprising a sample from a tissue wound. The docking station also includes means for docking a sensor in the station, which sensor detects the light reflected from an illuminated tissue wound, such that an image of the tissue wound can be communicated from the station to the processor. The means for docking is arranged such that when the sensor is docked in the station and the test substrate is received by the docking station, the sensor is positioned to detect the intensity of reflected light from the test substrate and communicates the detected intensity of reflected light to the processor to thus permit combined imaging of the tissue wound and test substrate. An apparatus for use in combined imaging of a tissue wound and a test substrate comprising a sample from a tissue wound, comprises such a docking station together with a sensor which detects the light reflected from a tissue wound and test substrate when illuminated and a test substrate for receiving a sample from a tissue wound. A method of imaging a wound comprises directing light over a wavelength range of less than 50 nm onto the wound (9). The light reflected from the wound (9) is detected with a sensor (5) that is sensitive to the intensity of the reflected light. The intensity of the reflected light is measured.L'invention porte sur une station d'accueil destinée à être utilisée en imagerie combinée d'une lésion tissulaire et d'un substrat de test comprenant un échantillon provenant d'une lésion tissulaire, la station d'accueil comprenant un moyen destiné à relier la station à un processeur traitant et mémorisant les images.
