Select an Inventory Entry

To edit an inventory entry, first select the entry in the list of database entries (Note: this screen capture has been anonymized, the entry highlighted in blue is named "My Tutorial").


After selecting an entry to edit, click the Edit button to open the inventory editor sheet.


The Inventory Editor Sheet
  • In the Radionuclide control group
    • Source name - if necessary, select a different source from the menu. If you created the inventory correctly it will already be linked to the correct physics file. However, you may optionally change the source model here.
    • Mfg. lot number - optionally enter the manufacturers lot number or any other identifying information such as the patient name.
    • Inventory name - enter a descriptive name for this inventory entry, typically this would be the name of the patient it is destined for.
    • Comment - optionally enter any other comments here.
    • Number of sources - enter the current number of sources available and the total number of sources in the lot. The popup menu fills both fields with common initialization values. The leftmost text field is the current seed count remaining in inventory, the text field closest to the popup menu is the number of seeds ordered. For a new entry, both entries should be initialized with the same number. The available count will decrease as seeds are installed in the plaque.
  • In the Calibration control group
    • Strength - In preferences you can choose to default to manually entering source strength as either the average or minimum and maximum of a lot. You can override the preference setting here.
    • Average - enter the the average source strength of the lot or simply select a source strength (e.g. 1.0) from the midpoints popup menu. The midpoints menu lists standard values from data in the physics file.
    • Min & Max - enter the the minimum and maximum source strengths of the lot. The leftmost text field is the lower end of the range. The rightmost ('to') text field is the upper end of the range.
    • Assay date - enter the assay date and time of the source strength either directly in the control, or optionally click the calendar button to open a calendar sheet.


Note: if you simply enter 1.0 as the source strength, you can use the Implant Calculator to determine the average source strength required at the time of implant to meet the surgical schedule. The inventory strength will be automatically updated and its assay date will be set to the time of implant.


Updating the plaque

The sources in a plaque are copies of the state of inventory entries at the time the source was pulled from inventory and put into the plaque.

Editing an inventory entry does not automatically propagate to the sources in the plaque. If you edit an inventory entry (e.g. change the calibration) and any of the plaques under consideration for the current patient contains sources from that inventory entry, you will be alerted when you close the editor sheet and offered a one time opportunity to update the sources in the plaque(s) to match the current state of the inventory.

Note: you will NOT be alerted to update plaques containing this inventory entry in other (e.g. past) patients.
