Controller for a microtome, microtome system and corresponding method

- 44 Abstract The invention relates to a controller for a microtome, wherein the microtome is config ured to cut slices from a sample block by means of a knife, wherein said controller is configured to: Control a display (320) to visualize a virtual representation (340) of the sample block, Receive first user input data, wherein the first user input data is indica 10 tive of a front surface of the sample block in the virtual representation of the sample block, Determine a virtual front surface (342) of the sample block based on the first user input data, Receive second user input data, wherein the second input data is in dicative of an edge (244) of the front surface of the sample block in the virtual repre sentation (340) of the sample block, Determine a virtual edge (344) of the front surface 15 of the sample block based on the second user input data, Receive third user input data (716), wherein the third user input data is indicative of a cutting plane intersecting the sample block in the virtual representation of the sample block, Determine a virtual cut ting plane intersecting the sample block, based on the third user input, and Determine alignment parameters for the microtome, based on the virtual front surface (342) of the 20 sample block, the virtual edge (344) of the front surface of the sample block, and the virtual cutting plane, wherein the alignment parameters define a relation between the virtual cutting plane, the virtual front surface of the sample block and the virtual edge of the front surface of the sample block. 25 (Fig. 3a) 324.1 324.2 344 320,322 342.1 342.2 324.4 342.3 Fig. 3a324.5 342.1 3263432 342.1' 340 Fig. 3b
