2 BD FocalPoint™ GS Imaging System Introduction
This section provides overview information on the basic operation of the BD FocalPoint™ GS
Imaging System and a brief review of the workflow process for orientation. Specific details on
how to operate the BD FocalPoint™ Slide Profiler and BD FocalPoint™ GS Review Station are
discussed in subsequent sections.
2.1 BD FocalPoint™ GS Imaging System
The BD FocalPoint™ GS Imaging System consists of the following:
• BD FocalPoint™ Slide Profiler
• BD FocalPoint™ GS Review Station
Slides are initially processed on the BD FocalPoint™ Slide Profiler, an automated screening
instrument. Each slide is scanned using 4x and 20x objectives. Digital images are captured and
processed by computers that use multiple algorithms to assess both squamous and glandular
changes as well as specimen adequacy. Each slide is given a score that corresponds to the
likelihood of abnormality. The slides are then grouped or batched into a unit called a print set.
The slides within each print set are statistically ranked based on their individual slide scores
(the scores represent the probability of abnormality). See Section 12 for details on creating a
print set.
In addition to ranking the slides, the BD FocalPoint™ Slide Profiler identifies specific fields of
view on each slide. These FOV represent the locations most likely to contain cells of interest.
The BD FocalPoint™ Slide Profiler also selects 15% of the highest scoring slides that were
initially reported as negative for quality control review. All BD FocalPoint™ Slide Profiler slide
information data, including the coordinates and cell images for the FOVs are transferred to a
central server or database. The slide information is retrieved by the cytotechnologist or
pathologist at the BD FocalPoint™ GS Review Station. Figure 2-1 demonstrates this relationship
between the BD FocalPoint™ Slide Profiler and the BD FocalPoint™ GS Review Station.
In summary, the BD FocalPoint™ GS Imaging System combines the automated primary
screening capability of the BD FocalPoint™ Slide Profiler with the precision field relocation
capability of the BD FocalPoint™ GS Review Station.
