Abstract
A digital slide scanning apparatus slide stage is configured to hold 1×3 and 2×3 glass slides. The slide stage is configured to alter its position by lateral shift or rotation to present the 1×3 or 2×3 sized recess to a slide rack for loading of the slide onto the stage. Also, a removable insert may configure the stage to hold a 1×3 glass slide when present and to hold a 2×3 glass slide when removed. Alternatively, a gripper stage is described herein that includes a fixed arm and a movable arm, each with one or more contact points configured to engage a side surface of the glass slide. Once the glass slide is secured between the contact points of the movable arm and the contact points of the fixed arm, the slide is further processed for scanning.
Claims11
A digital slide-scanning stage comprising:
- a base;
- a fixed portion comprising a fixed arm extending from the base in a first direction and having a first top surface and a first slide surface recessed below the first top surface by a first side surface, wherein the first slide surface is configured to support a bottom portion of a glass slide;
- and
- a movable portion comprising a movable, protruding arm extending in the first direction and having a second top surface and a second slide surface recessed below the second top surface by a second side surface, wherein the second slide surface is configured to support a bottom portion of a glass slide, the protruding arm configured to slide orthogonally to the first direction to change a distance between the fixed arm and the protruding arm;
- wherein the second side surface of the movable portion opposes the first side surface of the fixed portion to form a recess above the first and second slide surfaces, and
- wherein the movable portion is configured to move between at least a first position, having a first distance from the fixed portion, and a second position, having a second distance from the fixed portion, such that,
- in the first position, the first and second side surfaces and the first and second slide surfaces form a first recess of a first size configured to hold a glass slide having a first width dimension, and,
- in the second position, the first and second side surfaces and the first and second slide surfaces form a second recess of a second size configured to hold a glass slide having a second width dimension that is different than the first width dimension.

A digital slide-scanning stage comprising:
- a first fixed portion having a first top surface and a first slide surface recessed below the first top surface by a first side surface, wherein the first slide surface is configured to support a bottom portion of a glass slide;
- a second fixed portion having a second top surface and a second slide surface recessed below the second top surface by a second side surface, wherein the second slide surface is configured to support a bottom portion of a glass slide;
- and
- a third fixed portion having a third top surface, a third slide surface recessed below the third top surface by a third side surface, and a fourth slide surface recessed below the third top surface by a fourth side surface, wherein the third and fourth slide surfaces are each configured to support a bottom portion of a glass slide;
- wherein the third side surface of the third fixed portion opposes the first side surface of the first fixed portion to form a first recess, above the first and third slide surfaces, of a first size configured to hold a glass slide having a first width dimension,
- wherein the fourth side surface of the third fixed portion opposes the second side surface of the second fixed portion to form a second recess, above the second and fourth slide surfaces, of a second size configured to hold a glass slide having a second width dimension that is different than the first width dimension,
- wherein the digital slide-scanning stage is configured to move between a first position and a second position,
- wherein, in the first position, the first recess is in a position for scanning, and
- wherein, in the second position, the second recess is in the position for scanning.

A digital slide-scanning stage comprising:
- a first fixed L-shaped portion having a first top surface and a first slide surface recessed below the first top surface by a first side surface, wherein the first slide surface is configured to support a bottom portion of a glass slide;
- and
- a second fixed L-shaped portion having a second top surface and a second slide surface recessed below the second top surface by a second side surface, wherein the second slide surface is configured to support a bottom portion of a glass slide;
- wherein the first fixed L-shaped portion and the second fixed L-shaped portion both have first parallel portions, separated by a first distance, so as to form a first recess between their respective side surfaces and above their respective slide surfaces, wherein the first recess is configured to hold a glass slide having a first width dimension,
- wherein the first fixed L-shaped portion and the second fixed L-shaped portion both have second parallel portions, separated by a second distance that is different than the first distance, so as to form a second recess between their respective side surfaces and above their respective slide surfaces, wherein the second recess is configured to hold a slide having a second width dimension that is different than the first width dimension,
- wherein the first recess overlaps the second recess,
- wherein the digital slide-scanning stage is configured to rotate between a first position and a second position,
- wherein, in the first position, the first recess is in a position for scanning, and
- wherein, in the second position, the second recess is in the position for scanning.
