In Vivo Treatment Verification of Brachytherapy

Condition(s) studied

Investigational drug(s) / intervention(s)

External imaging panel: The IP will be placed on the side of the treatment table and will acquire data during the whole treatment, which will be compared against information derived from the treatment plan. The IP based method can detect errors and information about motion and treatment uncertainties that are not currently available.

Study summary

To acquire data during High Dose Rate (HDR) brachytherapy treatments aiming to track the brachytherapy source inside the patient verifying the delivery of the treatment plan.

Medical images (CT,MRI and US) combined with software developed by the investigator will be employed to predict the response of the Investigational product during the treatment and will be used as reference.The IP will be placed on the side of the treatment table and will acquire data during the whole treatment, which will be compared against information derived from the treatment plan. The IP based method can detect errors and information about motion and treatment uncertainties that are not currently available.

Eligibility

Primary outcome measure(s)

• Dwell times — 1 year
  Verify all relevant parameters of the HDR treatment plan during treatment delivery such as dwell times (time in seconds). Brachytherapy treatments are delivered using two parameters, the first parameter is dwell times (the duration the radioactive source stays in a dwell position, measured in seconds (s)). Our system measures dwell times, comparing them against expected values. Note that this parameter can be further used to derive other metrics, such as radiation dose distributions (units in Gray (Gy)), as defined by the TG-43 AAPM dose formalism.
• Dwell position — 1 year
  Verify all relevant parameters of the HDR treatment plan during treatment delivery such as dwell positions (distance in (milli)meters). Brachytherapy treatments are delivered using two parameters, the second parameter is dwell positions (a location where the radioactive source should stop, defined in centimeters (cm)) Our system measures dwell positions, comparing them against expected values. Note that this parameter can be further used to derive other metrics, such as radiation dose distributions (units in Gray (Gy)), as defined by the TG-43 AAPM dose formalism.
