Allows loading and correcting whole blood data located on the file system. The button activation opens a dialog window. In the upper part the current path is indicated. The program automatically points to the directory of the last successful loading operation. It has elements for changing the directory: the navigation buttons in the Folder section (.. indicating one level up). All files suitable for loading (having the right suffix, such as *.tac, *crv) in the search directory are listed in the Files section. The Open button starts loading the selected file, Cancel quits the operation, and Delete erases the file from the disk.

The button is located under the Load TAC to Be Corrected button. Its activation closes the displayed TAC. Subsequently, the graphic area becomes empty.

Allows saving the correction parameters (e.g. the calibration factor) determined in the Calibration Factor page. The saved file receives a .corrPars suffix and can be visualized in Excel or a text editor (e.g. Notepad).

Allows loading correction parameters already available on the file system. The calibration factor is read from the file and the dedicated field is updated accordingly.

Checkbox enabled: allows the selection of the radio isotope used in the experiment. Accordingly, the activity measurements are corrected for the decay.

The isotope half-life is displayed in seconds in the Half Time field.

Displays the time when the PET scan was started.

The text box allows the manual adjustment of start time of the PET scan. Consequently, the "X" symbol becomes active, allowing to reset the time to the original file start time.

In case no TAC was loaded the time setting area is gray and a message is displayed: Scan Time Not Available

Offset

Performs the subtraction of the background activity [counts/sec] from the measured TAC.

Manual radio button ON consents the user to interactively enter this value (generally around 100cts/sec).

Automatic radio button ON subtracts the first measured value from the TAC when PET and twilite acquisition started simultaneously. Differently, when the PET Scan Start Time must be adjusted the value to be subtracted is calculated as the average value over the delay time ([Aver]).

If the calibration checkbox is ON the correction for the calibration factor is applied to the curve (e.g. whole blood).

In case the Resampling checkbox is enabled the time can be inspected and the definition overwritten activating the Edit Timing button.

Select/Select from End: Allows selecting a subset of frames, from the first or from the last frame: From frame-x To frame-y with an increase step Inc.

Set to All: Allows setting the same sampling time to all existing frames. The Step and Duration must have the same value. It is a useful feature when the purpose is curve extrapolation. At the end the frame number is unchanged.

Set New Sampling: Allows defining a different ending time of the experiment in the Time Edition pane (From, To text boxes) with the same integration time (Step, Duration).The number of frames can differ from the initial ones.

Insert New Sampling: Allows the insertion of new frames within the existing ones or at the end of the experiment. Consequently, the frame number changes.

The Save Time/Retrieve Time buttons allow saving/retrieving the timing of the dynamic frames to/from a file.

Allows saving the corrected and calibrated curve. A confirmation window pops up allowing to save the corrected TAC either as a blood curve, .*crv, or as a tissue, .*tac. The saving procedure continues upon activation of the Yes button. Alternatively, it is possible to abort the saving selecting the No button.

Allows sending directly the corrected and calibrated curve to the kinetic module. Upon activation, a dialog window appears which allows defining the proper type of the calculated TAC (WHOLE BLOOD = spillover curve, PLASMA = input curve, tissue TAC (Region).

The Send[SET] button transfers the TAC data to the currently selected tab in the PKIN tool. If the Append TAC Data box is checked, the curves are appended as new curves to the data existing on the PKIN tab, otherwise the data is over-written.

The Send[ADD] first creates a new tab in PKIN, to which the data is added. If PKIN is not running, the tool is first started and the data added.

Cancel will abort any action.

The +- button in the curve controls allows for simple operations such as curve scaling before sending the data to PKIN.

The selection of this button closes the PSAMPLE Correction module.

Buttons dedicated for problem reporting. The capture button creates a capture of the entire screen (not only the PMOD window) and adds it to a buffer of up to 20 captures. The console button opens the Console dialog window.
