Diode Holder and Calibration Jig Diodes Not Included Item # Description 322-930 Diode Holder with Five Slots 322-932 Calibration Jig with Six Slots

Use VeriDose PDMQC as a patient dose monitor and when needed, just simply plug in the Veridose QC Module and VeriDose PDMQC is transformed into a precision linear accelerator quality control device.

VeriDose PDMQC is actually two radiation oncology products in one. It’s a linear accelerator quality control device (it measures beam constancy, which includes flatness and symmetry). It’s a five-channel patient dose monitoring system that records patient dose verification data from actual radiation measurements made on the patient during treatment. 

Accuracy:
• Measurements and updates are provided in real time, accurate to within 1% or better
• Automatically adjusts the proper offset voltage for each detector, resulting in up to ten times less drift than other products

Time-Savings:
VeriDose PDMQC stores up to 25 separate calibration sets. A calibration set can be created for up to 5 diodes at a time. As a result, the frequency of calibrations you do is significantly reduced. Setup time and error potential are also dramatically reduced, leaving more time for patient treatment.

Documentation:
• When interfaced with a standard printer, you can print:
1. Patient treatment dose reports
2. Date and time of procedure
3. Diode detector group and serial number
• In vivo measurements with VeriDose PDMQC as a patient dose monitor are reimbursable under CPT-4 Section 77331 Special  Dosimetry
