The milestone of the first proton beam delivery from a treatment gantry has been reached.
Protons have now travelled from the cyclotron, down the beam line and into Gantry 1.
This monumental stage in the project is down to the hard work of the project’s engineers. The project is moving ever close to treating our first patient.
Annual Radiotherapy Service Leads UK 2018
The Christie hosted the annual meeting of radiotherapy service leads from around the UK.
The radiotherapy service leads had the opportunity to complete a short tour of the new facilities.
James Donnelly, superintendent radiographer, said: “This has been a great opportunity to build relationships with colleagues from around the UK and to show the progress of the proton beam therapy service at The Christie.”

Proton Beam is moving ever closer
The Energy Selection System (ESS) has been under calibration for the past 4 weeks, this task is almost complete. The calibration occurs by placing a water tank into the beam line and taking a series of measurements.
The ESS comprises of a number of carbon wedges being placed into the proton beam path to facilitate changes in the proton energy. This change in energy corresponds to the depth treatment is delivered in a patient. Once completed the commissioning of the magnets, which position the proton beam in the treatment room, can begin. The proton beam will move into Gantry room 1 once completed, which is a huge milestone in the project.
Visit by CLIC Sargent Nurse educator (North)
The Christie proton beam therapy centre received a visit from Linda Sanderson this month. Linda is a CLIC Sargent Nurse Educator. Linda was keen to update her knowledge on the development of the centre and pass this onto other CLIC Sargent Nurses in the North of the UK.
“It was great to meet the expert team who are preparing to care for Children, young people and their families when the centre opens.” said Linda.
The proton team hopes to see Linda and her colleagues again in the future once we are up and running.
The Cyclotron commissioning is nearing completion. The cyclotron is the machine that accelerates protons up to an extremely high speed. Internal efficiency of the cyclotron is at 100%, with the extraction of protons currently at 82%. The cyclotron is working well within expected guidelines.
Energy Selection system (ESS) commissioning
The next part of the project underway is the commissioning of the Energy Selection system (ESS). The ESS allows different energies of proton beam to be available for clinical treatment. The energies range from 70 MeV to 250MeV. The commissioning is completed by inserting a water tank into the beam line and measuring the beam energy. Once this is completed, the proton beam is taken into Gantry room 1. This will happen over the next few weeks.
Beam Transport System (BTS)
Beam Transport System (BTS) has been leak tested in preparation for the proton beam to be taken into the different gantry rooms.
Gantry Room 1
Gantry room 1 has now completed installation of ProBeam Machine Control Software, and the gantry now moves under its own steam. This is a very important milestone. The treatment room is near completion ready for building handover next month.
Team site visit
Radiographers from the proton therapy team completed a site visit this month. The team was impressed with the progress of gantry 1 and had a sneak peek behind the scenes.
CT and MRI Scanners delivery and acceptance
Both the CT and MR scanners have been delivered installed and accepted. Both machines are now operational and staff have started to receive training.
Last week we took our first human images on the proton MRI scanner, those images were healthy volunteers from our staff group. They represent several very exciting milestones, including:
- The first persons scanned on the PBT MRI scanner
- The first human image captured on the Philips new MR RT scanner in the UK
- The first person scanned on The Christie’s first dedicated MR scanner for radiotherapy planning
Commissioning of both scanners has been started by radiotherapy physics and will continue for several weeks.
The first patient volunteers will be scanned on the MRI scanner and radiotherapy patients will be scanned on the new CT at the end of May.
Staff trip to Maryland, USA
Four of the new superintendent radiographers visited the Maryland Proton Treatment Centre in Baltimore, United States. The trip lasted a week, involving five working days in the department, becoming familiar with the equipment currently being installed at The Christie. It was especially useful for us to see how it is used by the “Radiotherapists” (as the staff are known in America). We learnt a great deal from the visit and were provided with a huge amount of support and time to answer the large number of questions we had. We all remarked how important the trip was, as no amount of UK based research could replicate the experience of working with a fully functioning department.
Appointment of the Band 7 radiographers
From February 2018, the Christie proton team has grown as more radiographers have come into post. The team consists of therapeutic and diagnostic radiographers from both sides of the profession. The new team is working to develop the proton beam service as we move ever closer to opening. Members of the team have completed training nationally and internationally to develop their skills to bring the most effective and efficient service to patients.
“I’m hugely excited and proud to join the team in this project of national importance, bringing PBT (Proton Beam Therapy) to The Christie and subsequently to the NHS for the first time. Having worked with the majority of the people recruited in various previous radiotherapy roles, I’m assured of the ability of the team to deliver what is required.” David Kirk Superintendent Radiographer
The team is keen to continue the development of the first NHS PBT service. #Christieprotons
Patient Engagement Day
The Christie proton therapy team has hosted its third patient engagement day. In attendance were many patients and carers who have previously had proton treatment in the US. The day was used to find out about their experience of receiving proton therapy. We wanted to know about the positive and negative experiences of the treatment. As this was the third patient engagement day, we also wanted to build upon ideas from the previous engagement days, to ensure we are on the right track. The staff were all really inspired by the patients and their stories and so grateful for their time.
James Donnelly, superintendent radiographer, said: “This has been my first patient engagement day. I have taken a lot on board, It has been good to see treatment from a patient`s perspective. This event is something I can reflect upon and use to help develop my skills in delivering proton beam therapy.”
It was a well-attended day and we hope it will result in patients who will feel well informed and well supported during their treatment at the Christie proton beam centre once we open.
Radiographer visit to Varian Clinical School and Maryland Proton Therapy Centre
Radiographers attended an intensive 3-day proton course hosted by the Maryland Proton Therapy Centre (MPTC) with international delegates from the US and Taiwan to learn the fundamentals of proton therapy theory, planning, treatment. The visit allowed us to learn from the experiences of the proton therapy centre, which has been treating patients for 18 months.
The radiographers had a one-week placement, shadowing the clinical staff on the proton treatment floor, which included time in the CT scanner and treatment gantries to get a full overview of the clinical proton practice. This helped to inform clinical decisions regarding treatment protocols, imaging protocols and patient information.
We are pleased to announce that all of the large treatment equipment for the proton therapy centre has now been installed in the building. The roof hatches have been closed and we no longer require the crane. This work has been completed about one month ahead of programme. Click here for further information.
