Please review and consider:
- are the claims appropriate, useful, sufficient
- would it make sense to move any claims to a different profile
Note: V-Cursor = Precursor Question about validating a Profile Claim; D-Cursor = Precursor Question about determining a Profile Detail
QIBA Profile: CT Lung Nodule Volume Quantification
Profile Claims (what users will be able to achieve)
Claim: Can create, store, retrieve images of lung nodules
- V-Cursor: None; proven DICOM
Claim: Can create, store, retrieve linear, area and volume measurements made on lung nodule images
- V-Cursor: None; proven DICOM
Claim: Can achieve accuracy of X and repeatability of Y
- V-Cursor: Demonstrate this accuracy and repeatability is easily achievable
- <Insert link to relevant Groundwork>
Profile Details (what equipment and users must do to achieve it)
The profile defines the following roles:
- Acquisition System
- Measurement System
- Measurer
- ...
Activity: Image Acquisition
Detail: The acquisition system shall support saving and using saved acquisition protocols
Detail: The acquisition system shall support the following acquisition settings
- D-Cursor: What acquisition parameters matter? (kVp, mA, …)
- <Insert link to relevant Groundwork>
- D-Cursor: What value ranges constitute an acceptable “baseline”?
- <Perhaps tie ranges to performance levels, e.g. Level 2 parameters might be sufficient for 1cm+ nodules, but Level 3 parameters are required for less than 1cm nodules>
Detail: The acquisition system shall produce images with the following characteristics
- D-Cursor: What image characteristics matter? (resolution, noise level?)
- <Insert link to relevant Groundwork>
Transaction: Image Exchange
Detail: The acquisition system shall support DICOM CT Storage as SCU.
Detail: The measurement system shall support DICOM CT Storage as SCP and DICOM Q/R as SCU
Activity: Measurement
Detail: The measurement system shall support the following measurements:
- D-Cursor: What measurements are useful for evaluating lung nodules
- RECIST <because it is the current gold standard and we need it to compare>
- Modified RECIST (J. Natl. Cancer Inst. 2008;100:698-711) <to support wider cancer etiology than HCC>
- Bitvol <because it is the typical “detailed” volume>
- <consider just adding a bunch of tools if they are easy to implement>
- D-Cursor: What accuracy is initially sufficient to be useful?
- D-Cursor: What repeatability is initially sufficient to be useful?
- D-Cursor: What accuracy/repeatability can be easily achieved?
- D-Cursor: What is the theoretical limit for accuracy/repeatability with typical equipment
- <Groundwork Link>
Detail: The measurer shall …
QIBA Profile: CT Lung Nodule Volume Change
Profile Claims (what users will be able to achieve)
Claim #1 Validation Precursor Groundwork Link users determine tumor volume changes to a certain level of accuracy across multiple acquisitions.
Profile Details (what equipment and users must do to achieve it)
Specification #1 Determination Precursor Groundwork Link
QIBA Profile: CT Lung Nodule Response
Profile Claims (what users will be able to achieve)
Claim #1 Validation Precursor Groundwork Link users evaluate tumor “response” to a certain degree of confidence
Profile Details (what equipment and users must do to achieve it)
Specification #1 Determination Precursor Groundwork Link
To Do
- Split other profiles to separate pages once the structure/content stabilizes a bit
- Review standard requirements traceability structures to see if they can help/be used
- Will likely regroup the Activity Details under the Roles
