Ver.1.5.9 OCT2009

1. Added indication of required and available disk
   space in the Acquisition Options dialog

2. Removed swapping filters after acquiring flat-field
   references for current mode only.

3. Fixed bug with possible blured first image in the
   acquired dataset and in the postscan for thermodrift
   compensation.

4. Reduced number of files in postscan for thermodrift 
   conpensation during extremely long main scan (20h+).

5. Fixed bug with filenames in the *.log files of the partial
   scans during connected scanning of the long objects.


Ver.1.5.8 MAY2009

1. Full support for thermal drift compensation by 
  reference post-scan (for details -> see document
  http://www.skyscan.be/next/thermal_correction.pdf)

2. Fixed bug in possible incorrect position of second
  and following segments in batch scan in the case of
  acquiring large format datasets.
 

Ver.1.5.7 NOV2008

1. After standard scanning control program saves
  several files with ".iif" and "oog" extensions for
  future usage.

2. During "TV-mode" and scanning object stage 
   temperature is shown in the left side of the status bar.


Ver.1.5.6 JAN2008

1. Oversize scan limited by safe margins to ensure
   that selected part can be fully reconstructed.

2. Added reminder to acquire flat-field reference
   every 30 days and realign scanner every 60 days.


Ver.1.5.5 JUL2007

1. Option to acquire flat-field references only for
    current mode in central position moved from
    "Scanner Settings" to "Acquisition modes"
    dialog.

2. Added support for scheduled scans from
   optional MTS stage.


Ver.1.5.4 MAY2007

1. Added possibility to lock stage elevation, stage
    movement to change magnification and camera
    movement to and from the source. Activation and
   deactivation: Ctrl+Alt+Shift+m



Ver.1.5.3 MAR2007

1. Check possibility to save flat-field references to
   avoid silent exit in attempt to rewrite read-only
   files.

2. Added indication of scanning in offset camera
    position into *.log file.



Ver.1.5.2 MAR2007

1. Added movement control for safe operation of the
   optional compression stage with load cell.

2. Added automatic recognition of the presence of the
   optional compression stage with load cell.

3. Fixed bug in engineering setup on attempt to acquire
    offset combined image without starting x-ray.


Ver.1.5.1 FEB2007

1. Fixed bug on mispositioning between scout image marks
   and scanning borders (mainly in 1.3Mp systems)

2. Added warning in the case of attempt to close control
   program during acquisition cycle.

3. Improved initialization procedure taking into account possible
   large object or optional stage in the top position with open door.



Ver.1.5.0 JAN2007

1. Changed datafolder selection dialog for direct sending
    data to any local or network drives.

2. Changed SetUp dialog in Flat-Field references acquisition: 
   "Clear" and  "Acquire" buttons replaced by Acquire 
   "Bright only" and "Bright+Dark". Acquiring only bright
   flat-field references after stabilization of x-ray source allow
   starting scans immediately.

3. Added support for two new types of 11Mp cooled 12-bit 
   digital X-ray cameras.

4. Fixed bug which can cause mismovement if option
   "Open door after scanning" selected in Acquisition dialog.

5. Added check for acceptance of preffix name by OS. 



Ver.1.4.3 JUL2006

1. Added tooltip window during moving mouse cursoe across
   scout image for vertical position estimation.

2. Left mouse click on the scout image indicates size of
   single scan, right click allows moving object to specific
   position.

3. Left double mouse click to the image after distance 
   measurement (by moving mouse with left button pressed)
   allows moving object up or down to vertical position in the
   end of measuring line.

4. Added possibilities to select single scan on the scout view.

5. Fixed bug with connected scans when last partial scan
   (top of the object) may be scanned in wrong position 
   because of object stage travel limit.


Ver.1.4 DEC2005

1. Added connection to the special object stages (positioning,
  compression/torsion, cooling/heating).

2. Added protection against multiple start of the program.

3. Fixed bug with incorrect acquisition using offset camera
   positions with nonstandard angular step size.

4. "About" box shows firmware version for all microcontrollers.


Ver.1.3 AUG2005

1. Implemented new strategy to acquire flat-field references:
  Firstly acquire all bright fields, then - all dark fields. Dark fields
  acquired with reduced set: identical dark maps are used for
  three camera offset positions. It allows reducing size of 
  necessary disk space for flat-field references. To reduce 
  disk space and improve flat-field correction quality we 
  recommend you to remove all old flat-field references from 
  the disk, make disk defragmentation and acquire new set 
  for all scanning modes.

2. In the "Acquisition modes" (Presets) dialog added checkbox
  to switch OFF x-ray after acquiring all required flat-field 
  references. Current camera mode inficates by arrow (->).
  Operator can change exposure time by up/down button
  across available values. In the case of setting exposure 
  time different from previously used, exposure field will be
  marked by star (*). This mark is used to acquire selected
  flat-field references. You can switch ON and OFF this mark
  by clicking in the exposure field for any mode.

3. The title bar in the "Acquisition modes" dialog indicates 
  currently used configuration.

4. Right mouse click in the imaging area switch ON or OFF
  profile displaying through the selected line. You can keep
  profile in the screen as long as you wish. Profile displaying
  not influent to the stored images or data acquisition.

5. Current camera position indicates in the right field of the
  status bar.

6. Scan duration added to the *.log file.

7. You can change the filter by mouse click to the status bar
  filter name indication.

8. Added indication of camera saturation in the right field of
  the status bar after every acquired image with >300 saturated 
  pixels.

9. Access to hardware settings dialog changed to Alt+Ctrl+Shift+h
  if setup functions are already accessable.

10. Scanning time estimation will be shown in H:M format for
  >1h left scanning time and in M:S format for <1h.

11. Added special fine movement of the object stage during
  specimen chamber closing and opening to follow the object
  shape. It allow to load the objects with diameter 66-67mm
  and length up to 75mm.



Ver.1.2 ( build 1) JULY2005

1. Fixed bug with incorrect saving flat-field references in
  user configurations.

2. Added possibility to restore factory preset configuration,
  which should be stored with name "std" in the program 
  home directory. After safety reason mark "std.cfg" and all 
  "std~*.*" files as" read onle"

3. Added option to switch OFF x-ray source after acquiring 
  several or all flat-field references in "Acquisition Modes".

4. Added compensation for object horizontal shift in lifting,
  defined by "Lifting incl." parameter in "Scanner Settings"

5. Added possibilities to modify scanner SN in "Scanner
  Settings" dialog.

6. Added indication of current configuration is the title bar
  of the "Acquisition Modes" dialog for exposure presets.

7. Added progress indication during saving and loading
  user configurations.

8. Added duration of the scan in the *.log file. 

9. Added camera position indication (far, middle or close 
  to the source) in the right field of status bar.


Ver.1.2 MAY2005

1. Added double size preview (in camera offset mode) to 
   Scanning Parameters Dialog.

2. Added partial scan with width 10%...99% and automatic
   corresponding correction for the angular step size.

3. Current mode/camera position/filter combination shown as
   highlighted in the Scanning Modes table.

4. Added oversize and multiple scans mode (Actions menu).

5. Added possibilities to change rotation step in the Scanning
   Parameters Dialog before any particular scan.

6. Added toolbar button for direct activation of Cluster-type
   reconstruction (NRecon).

7. Added toolbar button for direct activation of TVIEW.

8. Added direct access to this history file from "About" box.

9. Added available disk space estimation before start of scan.

10. Added possibilities to save, to load and to remove user
     configurations including all flat-field references. 

11. Right mouse click on the scout view moves object to
    selected vertical position.

12. Added up/dn buttons to pixel size selection by numerical
    values for changing magnification to next possible values.
