CASSETTES
A STORAGE PHOSPHOR CASSETTE consists of:
CASSETTE SHELL The SHELL is composed of a carbon fiber front and an
aluminum back, open on one side for removal and
insertion of the phosphor plate. A LATCH on the inside
of the SHELL holds the PLATE in place inside the
SHELL.
PLATE The PHOSPHOR PLATE consists of the PHOSPHOR
SCREEN and a rigid backing.
BARCODE LABEL Each CASSETTE has a unique BARCODE LABEL on
the SIDE-1 EXTRUSION for identification and tracking.
SIDE-1 The edge of the PLATE that the EXTRACTION BAR
EXTRUSION HOOKDS insert into to extract the PLATE from the
CASSETTE SHELL.
PLATE Plastic edge on the PLATE, opposite the SIDE-1
NOSEPIECE EXTRUSION, that helps to guide the PLATE back into
the CASSETTE SHELL.
PLATE Construction
A STORAGE PHOSPHOR PLATE consists of the STORAGE PHOSPHOR
SCREEN mounted to a rigid aluminum honeycomb panel that facilitates insertion
into the CASSETTE.
ST0RAGE PHOSPHOR SCREEN
The PHOSPHOR SCREEN is made up of an Estar base with a layer of phosphor
particles suspended in a polymer binding, a light absorbing black backing and a
lead back-scatter layer. The phosphor layer is covered with a protective coating
that extends beyond the edge of the phosphor to protect the phosphors from
physical and atmospheric damage.
