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 methods are 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.
Comparison of biometric measurement methods
After a lot of research, a special scanner has been chosen to measure the vascular bed. This blood vessel pattern is unique to each person. A palm scan is even more accurate than identification based on other biometric data, such as a fingerprint or an iris scan*. The false acceptance rate of a palm scan is 100 times lower than a fingerprint scan.
In addition, a palm scan can be applied more widely, because it is suitable for all patients. For example, medication does not affect the palm scan, while a fingerprint, for example under the influence of chemotherapy, may temporarily disappear. In addition, it works in a contactless manner which means that, for example, damp hands or deformation from excessive pressure cause no problems. In addition, scanning in a palm also works quickly. This is important, as the new identification method will be performed many times a day.
How does it work?
The new 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.
The palm scan will be available on the market in the near future for all radiotherapy institutes.
