An AI sales agent's X-ray room specification, checked before it goes out

An AI sales agent specifies a Carestream DRX-Compass radiography room for an imaging center: the tube, the tube positioner, the generator and the site power, the detector and how it connects, whether it sits in the wall stand, the heaviest patient and the tube heat capacity the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public DRX-Compass component specification and returns a verdict, every reason and the figures it computed.

Scope: DRX-Compass rooms: three Canon tubes, the overhead and floor-mount tube positioners, six generators and their site power, eight detectors, tube voltage, patient weight and stated tube heat units. See everything this validator covers

This validator models the DRX-Compass X-ray system from the public Carestream component specification (AK5184 Rev E), not just the scenarios shown below.

  • Tube and positioner — the Canon E7242X, E7252X and E7254FX tubes (up to 125, 150 and 150 kV; 200,000, 300,000 and 400,000 anode heat units), and the rule that the E7242X can be used only on the floor-mount tube stand, not the overhead tube crane.
  • Generator and site power — the CGF-80, CGN-50 and CGN-80 on three-phase 380/400/480 VAC, the CGF-50-2 on three-phase 208/220/240 VAC, the CGF-40-1 on single-phase 200 to 260 VAC and the CGF-50-SE stored-energy generator on single-phase 100 to 130 or 220 to 250 VAC; a low-speed tube goes to a person to confirm the generator output.
  • Detectors — Focus 35C, Focus 43C, Focus HD 35, Focus HD 43, DRX-Plus 3543C, DRX-Plus 4343C, DRX-Plus 2530C and Lux 35: which can be tethered and that the 2530C is for tabletop use, not the wall stand.
  • Exam needs — the kV the exams need against the tube, the heaviest patient against the 295 kg table limit, and the tube heat units the quote states.

Any DRX-Compass room built from these components is in scope — not only the scenarios pictured here. Not covered: prices (Carestream publishes no list prices here, so this page shows no price build-up), the table and wall stand models, collimators, grids, workstation software and options, other Carestream systems such as the DRX-Evolution, and generator mA output (the specification lists the CGN-80 under two output columns). Assumptions: the Focus detectors and the 2530C are read as not tethered because the specification lists them as wireless only; the specification is a distributor-hosted copy of Carestream document AK5184 Rev E.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Generators that fit only one site power supplyOnly with workarounds
Each generator is listed for one supply, so a rule has to read the generator on one line and the site power on another, for every pairing.		The generator and the site power are in one request and the match is checked with everything else.
A tube that can be used on only one positionerOnly with workarounds
The restriction depends on the tube on one line and the positioner on another, and a miss is usually found at installation.		Both are in the request and the restriction comes back as its own finding.
Which detectors can be tethered or used in the wall standOnly with care
A product rule per detector, kept in step with the specification.		The detector selects its connection and use limits inside one model.
Limits that depend on the tube: kV and heat unitsOnly with care
Each tube has its own voltage ceiling and heat capacity, so every exam value has to be compared per tube.		The tube selects its limits and every one is checked together.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1This is a low-speed tube, and the specification notes that the generator maximum kW output may be limited with a low-speed tube; a person should confirm the output meets the exam needs.
2The Canon E7242X tube can be used only on the floor-mount tube stand, not the overhead tube crane.
3The quoted generator is not listed for this site power supply.
4The exams need 151 kV; this tube goes up to 150 kV.
5The exams need 126 kV; this tube goes up to 125 kV.
6The quote tethers this detector, but it is listed as wireless only.
7The DRX-Plus 2530C detector is listed for tabletop use only, not for the wall stand.
8The heaviest patient weighs 296 kg; the table takes at most 295 kg.
9The quote states 400,000 heat units for the tube anode; the tube has 300,000.
10The exams need 140 kV; this tube goes up to 125 kV.
11The heaviest patient weighs 310 kg; the table takes at most 295 kg.
12The quote states 300,000 heat units for the tube anode; the tube has 200,000.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent specifies a Carestream DRX-Compass radiography room for an imaging center: the tube, the tube positioner, the generator and the site power, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public DRX-Compass component specification and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a DRX-Compass room with a Canon E7242X tube on the floor-mount tube stand, a CGN-80 generator on single-phase 200 to 260 VAC site power and a Focus 35C detector. The exams need up to 110 kV and the heaviest patient weighs 140 kg. The rest of the request is on screen. The quote states 200,000 heat units for the tube anode.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings and one approval, all in one answer. The quoted generator is not listed for this site power supply. The quote tethers this detector, but it is listed as wireless only.
    6. 
      
  6. The validator returned two blocking findings and one approval in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for generators that fit only one site power supply, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the generator to CGF-40-1 and the detector to DRX-Plus 3543C.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The two blocking findings are cleared; one approval remains for a person: low-speed tube may limit generator output.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the x-ray tube to Canon E7252X and the tube anode heat units as stated in the quote to 300000.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
