Triggered imaging is a technique unique to the TrueBeam linear accelerator (radiation therapy machine) and enables visual verification that a tumour is being accurately and precisely targeted. It is specifically used for prostate cancers.
This sophisticated technology uses markers that are implanted into the prostate. These markers allow radiation therapists to visualise the tumour during your treatment. It does this via low dose x-ray images generated throughout the treatment allowing the machine to automatically detect the position of the markers. Being able to constantly monitor the tumour allows your radiation therapists to account for any motion during your treatment.
The use of this technology results in consistently delivering the radiation with pinpoint accuracy to the tumour and reducing radiation to surrounding healthy tissue.
