An observation apparatus includes a case having a transmissive window, an image sensor, an optical system, and a light source housed in the case, and an optical deflection unit. The optical system is configured to condense light incident inside the case to form an image of a sample inside a container. The light source is configured to emit light to the outside of the case without passing through the optical system. The optical deflection unit is configured to deflect light emitted to the outside of the case from the light source to a first direction proceeding toward the transmissive window. An angle of exit between the first direction and an optical axis of the optical system is different from an angle of incidence between a second direction in which light emitted to the outside of the case is incident on the optical deflection unit, and the optical axis.
SENSITIVITY ANALYSIS FOR DIGITAL PATHOLOGY
The ability to obtain and digitise pathology samples (such as in histopathology or cytopathology) has opened up the possibility of accurate and automated computer operated analysis, or computer-assisted analysis, when diagnosing a wide range of medical conditions. A typical digital pathology image analysis pipeline involves a large number of image pre-processing and processing operations. Small changes in the parameters used in these algorithms might lead to significant changes in the eventual pathological finding. Accordingly, the present application proposes to perform a sensitivity analysis on a digital pathology image analysis pipeline to assess the sensitivity of a given pathology result to changes of parameters in the digital pathology image analysis pipeline.
