1.3 System Overview
The BD FocalPoint™ GS Imaging System combines the automated screening capability of the
BD FocalPoint™ Slide Profiler with the precision field location capability of the BD FocalPoint™
GS Review Station.
1.3.1 BD FocalPoint™ Slide Profiler
The BD FocalPoint™ Slide Profiler is an automated cytology screening device that classifies
slides for review according to their likelihood of containing an abnormality. Cell images are
captured using a high speed video equipped microscope and image interpretation software. The
software analyzes the complex images on a cervical cytology slide using screening algorithms.
The screening algorithms are comprised of over 100 object analysis features, including both
squamous and glandular algorithms to determine potential abnormality. The device is intended to
detect slides with evidence of squamous carcinoma and adenocarcinoma and their usual
precursor conditions.
1.3.2 BD FocalPoint™ GS Review Station
The BD FocalPoint™ GS Review Station receives slide processing results data from the
BD FocalPoint™ Slide Profiler and presents the results data to a cytotechnologist to assist the
cytotechnologist in interpretation of the specimen on a slide. The slide results include slide
identification information, ranking and sorting information, specimen quality indicators,
associated cell pattern images, slide reference frame data, and processing status indications for
each slide via a network connection.
1.3.3 LOI versus FOV
The BD FocalPoint™ GS Review Station provides rapid data retrieval and rapid navigation to
locations of interest (LOI) on the slide. When the microscope stage is focused on one of these
locations, the area visible to the cytotechnologist through the microscope is referred to as the
field of view or a FOV. These two terms are not interchangeable, but are often used to refer to the
same point on a slide. The correct term to describe a particular point on a slide depends on the
context.
