Total QA allows you to create your own custom test groups and individual tests so that you can accommodate any regulatory or institutional protocols and requirements.
Test groups allow you to organize your individual tests into logical groupings corresponding to protocols or checklists. Within groups, tests are organized by subgroups. For example, in the built-in TG142 tests the tests are generally grouped by the main tables in the TG142 report and then subgrouped by test type (dosimetry, mechanical etc.) to correspond to the TG142 table subdivisions.
All individual tests in Total QA are created as part of a test group and subgroup. Individual tests can accommodate numerical, pass-fail, pass-fail warning, document attachment, and text entry type tests.
To create and manage custom tests, navigate to the "Manage - Custom Tests" page.
Adding Custom Test Groups and Tests
If you have not previously added any custom tests you will see a button to add an initial main test group. Click the Add Group button to open the Create Group dialog.
In the Create Group dialog, you will add a label. This will be the label that will be displayed when creating templates. You may optionally add a description for the group. Select device type(s) for this custom test group. The test group will only be available for templates with the corresponding selected device types. To have the group available for all templates select the Other device type.
When you are ready to add the group click the Add group button. To cancel the addition click the Cancel button.
Once you have a group established you can add subgroups under that groups. The create group dialog for subgroups is the same as for the main group. After establishing one or more subgroups you may add tests to each of the subgroups.
Clicking the Add test button opens the Create Test dialog. Enter the test parameters to configure the test.
- Name: This is the name that will be displayed when you are creating a template.
- Subname: Label for the parent test used if child tests are added.
- Description (Optional): A description of the test.
Descriptions may be richly formatted and include images
- Type: Choose the test type. Note that the test type may not be changed after creation.
- Numeric: A test that requires a numerical entry. Units may be specified
- Numeric Energy-Dependent (photon): A numeric test that will be associated with specific photon energies. Units may be specified
- Numeric Energy-Dependent (electron): A numeric test that will be associated with specific electron energies. Units may be specified
- Deviation: A numeric test where the final result is the deviation between the entered value and a nominal value. Units may be specified. The deviation test may be designated a percentage deviation test in which case the final result will the percentage difference between the nominal and measured quantities ( (Nominal-Measured)/Niminal x 100% ). A deviation test may also be identified as angular. Note that a meta-item containing the Nominal entry will automatically be created for deviation type tests. To edit the label please see Adding and Managing Meta-Items below.
- Ratio: A ratio test will calculate the ratio of an entered numerator divided by an entered denominator. Numerator and denominator labels may be customized. Units may be specified. If the numerator and denominator units are identical the ratio will be considered unitless and will not display a unit. If they are different the ratio will display with units of numerator_unit/denominator_unit.
- Pass/Fail: A binary choice between pass and fail.The labels on the buttons can be edited.
- Pass/Fail/Warning: A trinary choice between a pass, fail and warning.The labels on the buttons can be edited.
- List: A list of text options.
- File attachment: Allows a file attachment containing test results.
- Text: Allows a free form text entry.
- Allow multiple values?: If 'Yes' is selected then a button allowing multiple entries will be present when performing QA with this test.
Managing Custom Test Groups and Tests
To manage groups and tests after they are created click the Manage button next to each group, subgroup or test. This will open the appropriate dialog to change the group or test parameters.
Limitations on changing group and test parameters:
- The test type may not be changed once the test has been created.
- Tests and subgroups may not be reassigned to different subgroups or groups.
Changing Group and Test Visibility
To make subgroup and tests visible toggle the Show/Hide button next to each subgroup and test. Clicking the button when it displays 'Show' will turn visibility on and change the label to 'Hide'. Clicking the button when it says 'Hide' will turn off the button visibility and will change the label to 'Show'. Hiding a group or subgroup will hide all subordinate subgroups and tests.
If a number of test are marked hidden, the page can become cluttered. Hidden tests can be hidden from view on the Manage Custom Tests page by changing the Hidden Test Display button to off.
Deleting Custom Groups, Tests, Meta-items and Child Tests
Custom tests, meta-items and child tests may be deleted under the following circumstances:
- Groups and subgroups may be deleted if they contain no tests or subgroups.
- Tests may be deleted if they are not part of any template and have not had any data saved against the test.
- Meta-items and child tests may be deleted if no records using the meta-item or child test have been saved.
If the conditions above are met a delete button will appear next to the item and it may be deleted. If the conditions are not met the item may only be hidden.
Adding and Managing Meta-Items
Meta-Items are pieces of information that are associated with the test during entry. This can include items such as dose rate, field size and other information to segment the data. To add a meta-item to a custom test click the Meta Items button for the test.
When the add meta item dialog appears you can add up to a maximum of 10 meta-items. Meta-items may be one of three types:
- Numeric: When setting up numeric tests you can also assign a unit to the meta-item to guide the user when entering the data.
- List: Custom lists can be created from which the user will choose from at run time. For example, you could have a list of field sizes.
- Text: This type of meta-item is designed when the user is expected to add free-form text to the test.
Once you have entered the meta-item's parameters click the Update meta items button to add the meta-item to the test. To edit the meta-item click on theMeta itemsbutton again. Note that although you can change description and other text fields you cannot change the meta-item type. You can prevent the meta-item from appearing by clicking the Hide button next to it.
Once meta-items are added their values can be preset when setting up QA settings for a scheduled template that uses the custom test.
Adding Child Tests
Child tests can be added to a test. To add a child test to an existing test click the Create Child Test button.
This will open a dialog for adding child tests. The allowed types for child tests are more limited than for top-level tests.
After adding several child tests to a test the order of the tests can be adjusted by dragging them up and down in the list.
During data entry, this will display the main test and child tests horizontally across the page.
Using Custom Tests
Once custom test groups and tests are established they may be used like any other set of tests when creating templates. All the visible groups and tests will appear at the end of the available tests .
