Radiotherapy, Nuclear Medicine and Cyclotron Commissioning

Radiotherapy, Nuclear Medicine and Cyclotron Acceptance Tests

Commissioning & Acceptance in Radiotherapy, Nuclear Medicine and Cyclotrons is the combined process of equipment testing, system configuration and verification checks, needed in order to get any heavy radiation equipment ready for clinical use.

 

Radiotherapy, Nuclear Medicine and Cyclotron Commissioning

Linear Accelerator and Treatment Planning System (TPS) Commissioning and Acceptance

Nowadays there are two major types of devices subject to commissioning and acceptance in any common Radiation Oncology installation:

 

Treatment Planning Systems (TPS) commissioning comprises all the tasks of measuring your beam data, importing it to the system and validating the final configuration.

 

Linear Accelerators (Linacs) commissioning includes equipment acceptance and complete QA coverage to insure full conformance of these medical devices.

 

To give our customers more flexibility Mercurirus Health (MH) provides both solutions independently or in a combined pack.

 

TPS commissioning - What does it include?

  • Beam data acquisition for selected energies.
  • Linac non-dosimetric configuration.
  • Beam data import and configuration.
  • Validation of TPS calculations in a wide range of setups.


Linac commissioning - What does it include?

  • Equipment acceptance.
  • Quality Assurance according to reference protocols (TG142, etc...).
  • Dose Calibration.
  • Reference QA for special techniques implementation (IMRT, Radiosurgery, VMAT or RapidArc).


External Commissioning – benefits

  • Experienced Team with more than 40 TPS and 20 Linacs commissioned, ensures execution with the utmost rigor and high quality standards.
  • Time savings arising from experience and process optimization.
  • Experience with measurement equipment from all common manufacturers.
  • Experience in TPS and Linacs manufacturers from all common manufacturers.
  • For previously existing installations (with other Linacs still at work), no need for staff allocation and consequent interruption or reduction in regular activity.

Commissioning and Acceptance in Nuclear Medicine

Nowadays there are three major types of devices subject to commissioning and acceptance in any common Nuclear Medicine installation:

 

Gamma-Cameras (GC) - commissioning comprises all the tasks of insuring full conformance of the equipment in terms of energy window, sensitivity, spatial resolution or center of rotation among others.

 

PET/CT commissioning includes equipment acceptance and complete Quality Assurance coverage to insure full conformance of these medical devices, including the SUV validation, mandatory to begin the clinical work properly.

 

Besides these two types of equipment it is necessary to perform acceptance and Quality Assurance of the Dose Calibrators (DC) used in radiopharmacy to measure activities.

 

To give our customers more flexibility Mercurius Health provides these solutions independently or in a combined pack.

 

Gamma-Camera commissioning - What does it include?

  • Physical inspection;
  • Quality Assurance according to reference protocols (NEMA, IEC standards);
  • Collimator touch pad and gantry emergency stop;
  • Energy window setting for 99mTc and other radionuclides to be used;
  • Background count rate;
  • Intrinsic/extrinsic uniformity and sensitivity (visual and quantitative);
  • Spatial resolution;
  • Linearity;
  • Multiple window spatial registration;
  • Pixel size;
  • COR calibration.


PET/CT commissioning - What does it include?

  • Physical inspection;
  • Quality Assurance according to reference protocols (NEMA, IEC standards);
  • Uniformity;
  • Normalization;
  • Calibration factor from image voxel intensity to rue activity concentration – SUV validation;
  • Spatial resolution;
  • Sensitivity;
  • X-ray CT – numbers, alignment and performance.


Dose Calibrator commissioning - What does it include?

  • Constancy;
  • Stability;
  • Accuracy;
  • Linearity.


Though these are the most important, there are other equipments that should be tested and accepted before clinical utilization such as non imaging intraoperative probes, gamma counting systems or radiation monitoring devices.

 

External Commissioning – benefits

  • An experienced team ensures execution with the utmost rigor and high quality standards;
  • Time savings arising from experience and process optimization;
  • Experience with measurement equipment and phantoms from all common manufacturers;
  • Experience in GC and PET/CT equipments from all common manufacturers.
  • For previously existing installations (with other equipments still at work), no need for staff allocation and consequent interruption or reduction in regular activity.
