Process for the evaluation of cell pictures

Claim 2

A computer-aided, observer-interactive process for evaluating cell culture pictures in which several pictures of the same culture are taken chronologically and stored in digital form, comprising the steps of: successively recording and storing digitally pictures of a field encompassing at least a portion of the culture and having a size selected so that several individual cells will be located therein; sequentially displaying the digital pictures, in chronological order, on a video screen; marking the various individual cells in the first digital picture, each of the various cells or cell groups being provided different respective identifying marks; automatically marking the various individual cells with said different respective identifying marks in at least a second picture by computer means; interactively reviewing said automatically-provided identifying marks in sequentially displayed pictures by the observer for correcting any erroneously positioned marks; and storing digitally the position and number of each of the respective identifying marks in each sequential digital picture.

Claim 3

The process of claim 1 wherein, during said display step, each sequentially displayed digital picture is compared with the just previously displayed picture and positionally adjusted for equipment drift.

Claim 4

The process of claim 1 wherein each sequentially displayed digital picture adopts the respective markings of the just previously displayed picture and, during each said interactive reviewing step, the observer identifies cell variations by shifting such respective markings or by the addition of new identifying marks.

Claim 5

The process of claim 1 wherein the interactive reviewing step includes providing successive generations of cells with respective distinguishing marks, said process comprising the further step of determining and storing the number of marked cells in each successive generation.

Claim 6

The process of claim 1 comprising the further step of determining and storing the cell division rate for each differently marked cell or group of cells.

Claim 7

The process of claim 1 comprising the further step of determining and storing the mobility of each differently marked cell or group of cells.

Claim 8

The process of claim 1 comprising the further step of forming and displaying a pedigree chart on a video screen for each differently marked cell or group of cells.

Claim 9

The process of claim 1 wherein said process is repeated for a plurality of successive picture fields, each bordering at least one other such successive field and each encompassing a different area of the same cell culture being evaluated.

Claim 10

Apparatus for taking and evaluating cell culture pictures in which several pictures of the same culture are taken chronologically, stored in digital form, and then sequentially displayed for review by an observer, comprising: a microscope having a stage for holding a cell culture specimen to be examined, said staging positionable in at least two directions; television means for recording video pictures of the specimen; picture memory means for digitally storing said video pictures; a monitor for displaying said stored video pictures; electronic marking means, operable by said observer, for inserting a plurality of different identifying marks onto pictures displayed on the monitor; computer means for positioning said stage, for actuating said memory means to store said video pictures chronologically, for sequentially displaying said chronologically stored pictures on the monitor, and for storing the number and position of each identifying mark inserted on each sequentially displayed picture; and programming means for evaluating said stored information relating to the number and position of the identifying marks; said computer means including means for displaying, for each said sequentially displayed picture, the respective identifying marks as inserted or repositioned by said observer-operated electronic marking means.

Claim 11

Apparatus for taking and evaluating cell culture pictures in which several pictures of the same culture are taken chronologically, stored in digital form, and then sequentially displayed for review by an observer, comprising: a microscope having a stage for holding a cell culture specimen to be examined, said staging positionable in at least two directions; television means for recording video pictures of the specimen; picture memory means for digitally storing said video pictures; a monitor for displaying said stored video pictures; electronic marking means, operable by said observer, for inserting a plurality of different identifying marks onto pictures displayed on the monitor; computer means for positioning said stage, for actuating said memory means to store said video pictures chronologically, for sequentially displaying said chronologically stored pictures on the monitor, and for storing the number and position of each identifying mark inserted on each sequentially displayed picture; and programming means for evaluating said stored information relating to the number and position of the identifying marks; said computer means including means for displaying, for each said sequentially displayed picture, the respective identifying marks as inserted or repositioned by said observer-operated electronic marking means.
