CNERGY Go – Biometric patient identification

Reliable patient identification is crucial in radiotherapy. Every radiotherapy patient is different, so treatment can vary enormously in terms of dosage and location on the body. This means that it is essential to correctly identify each patient and ensure they receive the correct treatment. Nowadays the checks are done mostly manually; for instance, checking the patient’s date of birth or using a photograph of the patient. These patient identification methods can be error-sensitive, as these checks are not integrated into the workflow and it can never be 100 percent certain that these steps are being used every time. Together with the Radiotherapy group in Arnhem, Cablon Medical has made another step forward with use of a palm scan connected to the accelerator, CNERGY Go.

Key features:

  • Accelerator does not start radiation before a positive match is made
  • Fully integrated into the existing workflow of radiotherapy centres
  • Optional waiting room module for patient guidance and attendance
  • Is fast, non-invasive and highest accuracy(FAR <0.00008%)


  • Prevents treatment of the wrong patient
  • No additional workload
  • Enables an organisation to maintain records for compliance purposes
  • On-table verification usable for every patient to minimize safety risks

Comparison of biometric patient identification methods

After a lot of research, a special scanner has been chosen to measure the vascular bed. It identifies the patient
through the unique hand palm vein profile. The blood vessel pattern is unique to each person and is more
accurate than other biometric identification methods, such as facial recognition and iris scan.1 The false acceptance rate of a
hand palm scan is 100 times lower than a fingerprint scan.1

In addition, it works fast2 and is suitable for all patients, even the ones that need to undergo chemotherapy
and whose fingerprint may temporarily disappear. It works in a contactless manner which means that, for
example, damp hands or deformation from excessive pressure cause no problems. This is important, as patient
identification will be performed many times a day.

How does CNERGY Go work?

The new patient identification procedure will involve the patient signing up at the desk to be enrolled. Both hands are scanned. The scan is stored as an encrypted code in the system and inseparably connected to the patient.

For every treatment the patient’s hand is scanned when the patient is on the treatment table. The scanner is portable, making it easy to identify patients accurately and quickly. The patient identification step cannot be omitted, because the accelerator cannot be started until a positive identification has been made.

If a patient cannot use the scanner for whatever reason, a radiation technologist can be nominated to unlock treatment with their own unique palm signature (override). This solution also enables an organisation to maintain immaculate records for compliance purposes.

In addition to the registration and verification procedure, a module for patient attendance is now available.
