Description: Automation of timeout of radiation field parameters prior to treatment of the patient: linac and safety culture
radiation oncology (48) timeout (33) radiation safety (22) linac (5) field time out (2) treatment safety (2) treatment verification (2)
It is generally accepted practice in Radiation Therapy to perform manual verification of each treatment field prior to delivery. Such verification is commonly referred to as per field time out and is performed either prior to every fraction or prior to the first fraction of each treatment phase. This time out is performed in addition to The Joint Commission time out, which verifies patient identity.
Per field time out is performed manually: one therapist reads parameters aloud from linac/MLC screen and another therapist verifies them against plan write up (on the treatment card), or, from the plan printout, either on the paper, or electronic, in the form of PDF document.
Our software, RTeye, which performs the electronic time out, automatically reads data from the linac screen and compares it to the data from the plan pdf printout. Parameters that are not available on linac screen, e.g. bolus or MLC segments, are conveniently highlighted for the therapist to check.
