Abstract
A sample processing apparatus has an associated machine vision system. The vision system may acquire an image of at least one fluidic chamber, which can be analyzed by the machine vision system and/or stored. The image and/or analysis of the image may provide a record of the actions of the sample processing apparatus, which permits a user to verify proper operation of the sample processing apparatus.
Claims19
A method for monitoring a sample handling process, comprising:
- associating a liquid sample with a fluidic chamber;
- performing the sample handling process with liquid sample with respect to the fluidic chamber, the sample handling process including a change in state of the liquid sample with respect to the fluidic chamber;
- using a machine vision system to acquire a 2-dimensional image of at least a portion of the fluidic chamber before, during or after performance of the sample handling process;
- and
- storing the acquired image to allow later verification of the change in state of at least a portion of the liquid sample during the sample handling process.
2 more elements
A sample handling apparatus, comprising:
- at least one fluidic chamber adapted to hold a liquid sample and allow for a change in state of the liquid sample relative to the fluidic chamber;
- and
- a machine vision system having an image acquisition device positioned to acquire a 2-dimensional image of at least a portion of the fluidic chamber, the machine vision system being adapted to allow verification of the change in state of the liquid sample relative to the at least one fluidic chamber based on the image.
