5 Storage phosphor screen scanning only:
Phosphor Mode selection ( Fig 4-1 , E):
• Best Resolution
Use this parameter if you require higher resolution than sensitivity. Use Best
Resolution with the 50- and 25-µm pixel sizes.
• Best Sensitivity —Use this parameter if you require higher sensitivity (limit of
detection) than resolution. Use Best Sensitivity with the larger pixel sizes
(above 100 µm).
6 The grid in the Typhoon Scanner Control window ( Fig 4-1 , F) is used to select the
scan area. The letter and number markings correspond to the markings in the
Exposure cassette (if performing Storage phosphor screen autoradioagraphy) and
on the glass platen of the
Typhoon instrument. The white rectangle on the grid
designates the area to scan. Use either the current scan area or select a new one.

a) Place the pointer in the grid square corresponding to the lower left corner of
the area you want to scan (A1 in the example in Fig 4-1 ,).
b) Drag the pointer to the grid square corresponding to the upper right corner of
the area you want to scan (J15 in the example in Fig 4-1 ).
c) Release the mouse button. The scan area selected appears in white.
7 Set sample orientation by selecting desired Orientation button ( Fig 4-1 , G).
There are 8 possible orientations and the selection determines how the scanned
