Accuray linear accelerators in radiotherapy

Accuray is a manufacturer associated with radiotherapy platforms. The machine name alone does not show which radiation technique, dose, or schedule a person will receive. Those details come from an individual treatment plan created by the radiation oncology team.

A linear accelerator produces high-energy radiation outside the body and directs it toward a defined target. Planning images are used to map the tumour or treatment area and nearby organs. During delivery, the equipment may move around the patient, shape beams from different directions, and use images to check alignment.

The experience depends on the platform and technique. Some systems deliver many shaped beam angles; others can follow or account for certain target movements. You are positioned carefully and the radiation therapists leave the room while the beam is on, but they continue to watch and communicate with you.

Follow the department’s instructions about eating, drinking, bladder filling, bowel preparation, medicines, and skin products because these vary with the body area. Wear comfortable clothing and arrive early enough for positioning. Tell the team if pain, coughing, anxiety, or difficulty lying still could affect the setup.

Before treatment starts, confirm the treated area, expected session routine, side effects linked to that area, and how your position will be reproduced. Do not worry if the machine rotates, pauses, or makes unfamiliar sounds; these can be normal parts of imaging and beam delivery. Use the communication system if you need the therapists to stop.

Report worsening skin soreness, uncontrolled nausea or vomiting, difficulty swallowing, new shortness of breath, fever, or pain that is not controlled; the relevant symptoms depend on the area treated. Seek emergency care for severe breathing difficulty, collapse, a seizure, heavy bleeding, or sudden weakness. The machine itself does not make you radioactive after standard external-beam treatment.

Ask which technique the team will use, why it suits the target, what positioning or immobilisation device is needed, and whether organ motion matters. Request clear instructions for preparation, expected side effects, after-hours contacts, and any circumstances that would lead to replanning or a treatment pause.
