A pressurised-ionisation-chamber dose calibrator with 5-second measurement cycle, MBq and mCi readout, and user-configurable calibration factors per isotope and per source geometry. CDSCO approved and AERB compliant — the essential activity meter for every nuclear medicine hotlab and radiopharmacy.
| Detector type | Pressurised well-type ionisation chamber |
| Calibration factors | Operator-set per isotope **and** per source geometry — no pre-programmed factors. The hotlab establishes the factor against a NIST-traceable reference of known activity in the same geometry used for patient doses. |
| Geometry handling | Independent stored factor per geometry (vial, syringe, dose pot, dose dispenser, capsule). Adding a new container type means establishing and storing a new factor before clinical use. |
| Measurement time | 5 seconds per reading |
| Activity display units | MBq and mCi (switchable) |
| Activity range | kBq to GBq scale (isotope- and geometry-dependent) |
| Reproducibility | ≤ 0.5% |
| Background correction | Automatic background subtraction |
| User interface | Touchscreen tablet, dedicated software, USB connection to ionisation chamber |
| Power resilience | Internal battery on ionisation chamber — maintains stability during power outages |
| Data output | Touchscreen readout; USB connectivity for records / printing |
| Compliance | CDSCO approved (Indian medical-device registration); AERB Technical Standards for Nuclear Medicine Facilities |
Activity measurement — the foundation of nuclear medicine QA
Measure generator eluate, radiopharmaceutical preparations and unit doses before patient administration. Mandatory QA step in every nuclear medicine hotlab.
Verify final product activity after Tc-99m cold-kit labelling, Ga-68 synthesis or Lu-177 DOTATATE preparation. Confirms dispensing accuracy before release.
Measure residual activity in vials, syringes and waste containers for radioactive decay management and AERB-compliant waste disposal records.
Accurate activity measurement for high-dose I-131 and Lu-177 therapy preparations. 5-second cycle minimises operator exposure during high-activity measurements.
Eluate activity measurement post-elution to verify generator yield and confirm consistency with stated calibration values.
AERB-required daily constancy checks and periodic linearity testing. Built-in logging and print functions support regulatory audit trails.
A calibration factor is not just isotope-specific — it is isotope **and** geometry specific. The same Lu-177 activity in a 10 mL P6 vial reads differently from a 3 mL syringe or a tungsten dose pot. The Vexcal stores an independent factor for every isotope-geometry combination the lab uses, so the operator is never relying on a pre-programmed factor that silently assumes the wrong container.
A 5-second cycle keeps pace with busy morning dispensing sessions — measure, record, move on. Critical for PET departments where Ga-68 half-life (68 min) demands rapid workflow from synthesis to patient.
CDSCO approval covers the Indian medical-device registration. AERB Technical Standards for Nuclear Medicine Facilities frame the dose calibrator QA requirements — daily constancy, annual accuracy, periodic linearity, geometry-specific factors. The Vexcal supports the full workflow with documented records the inspection officer expects.
