METHOD FOR DIGITALLY COLLECTING A SAMPLE BY A MICROSCOPE
The invention relates to a method for digitally collecting a sample by a microscope. In order to obtain a rapid analysis of the sample by a physician, it is advantageous if the sample has been already collected in regions which have not yet been viewed by the physician. This can be achieved when a viewing section of the sample is selected, a microscope lens is moved in a scanning mode over this viewing section first in a sequence of offset images covering the viewing section. The image is digitally recorded and the represented, and subsequently the scanning route is continued with a sequence of images outside of the selected viewing section.
1 . A method for digitally collecting an image of a sample ( 6 ) by a microscope ( 16 ), comprising:
selecting a viewing section ( 44 ) of the sample ( 6 );
moving a microscope lens ( 18 ) is moved in a scanning route ( 50 ) over this viewing section ( 44 ),
digitally collecting and displaying first a sequence of mutually offset images ( 52 ) covering the viewing section ( 44 ); and
subsequently continuing the scanning route ( 50 ) with a sequence of images ( 52 ) outside the selected viewing section ( 44 ).
2 . The method according to claim 1 , wherein the scanning route ( 50 ) is guided within the viewing section ( 44 ) outwardly from the centre of the viewing section ( 44 ).
3 . The method according to claim 1 , wherein the scanning route ( 50 ) is continued outside the viewing section ( 44 ) in a manner extending outwardly in a spiral manner around the viewing section ( 44 ).
4 . The method according to claim 1 , wherein once the viewing section ( 44 ) has been moved, any regions present that have already been imaged are displayed and those regions of the viewing section ( 44 ) that have not yet been imaged are collected first by the microscope lens ( 18 ).
5 . The method according to claim 1 , wherein in order to display the sample ( 6 ) in the viewing section ( 44 ), reference is made first to one or more non-current collected images with current microscope settings, which non-current collected images are covered image ( 52 ) by image ( 52 ) by the current sequence.
6 . The method according to claim 5 , wherein the display of the non-current collected image is distinguished from the display of a current image in such a way that a distinction between the non-current collected image and a current image ( 52 ) is made possible.
7 . The method according to claim 5 , wherein the non-current collected image is at least part of an overall collected image of the sample ( 6 ).
8 . The method according to claim 5 , wherein the non-current collected image was collected in a different spectral range compared to the sequence of the images ( 52 ).
9 . The method according to claim 5 , wherein
the non-current collected image was collected with a different focus position in the sample ( 6 ).
10 . The method to claim 1 , wherein pixel binning of a detector ( 20 ) collecting the images ( 52 ) is performed depending on the size of the viewing section ( 44 ).
11 . The method according to claim 1 , wherein an exposure time of the images ( 52 ) is selected depending on the size of the viewing section ( 40 ).
12 . The method according to claim 1 , wherein a spectral channel selection of the images ( 52 ) is performed depending on the size of the viewing section ( 44 ).
13 . A digital microscope ( 2 ), comprising:
a sample holder ( 4 );
a microscope lens ( 18 );
a drive ( 12 , 26 ) for moving the microscope lens ( 18 ) relative to the sample ( 6 );
a camera ( 22 ) for collecting an image of the sample ( 6 ) through the microscope lens ( 18 );
a control unit ( 28 ) for controlling the drive ( 12 , 26 ) and the holder; and
a display means ( 36 ) for displaying the collected image, wherein the control unit ( 28 ) is programmed to move the microscope lens ( 18 ) in a scanning route ( 50 ) over a viewing section ( 44 ), to digitally collect a sequence of mutually offset images ( 52 ) covering the viewing section ( 44 ), and to subsequently continue the scanning route ( 50 ) with a sequence of images ( 52 ) outside the current viewing section ( 44 ).
