Bedford Hospital has been providing healthcare services to people living in and around Bedford for over 200 years. In late 2011, approval was granted for the installation of a second CT Scanner to meet increasing demand for appointments & improve patient experience. The GE Optima 16 slice unit was installed in an existing room which required additional radiation shielding to house the new machine.
5 tonnes of lead shielding was installed on the walls and ceiling. Calder also supplied and fitted a 2100mm x 1100mm RD50 lead glass observation window.
London’s Royal Marsden Hospital, which is the world leader in the diagnosis and treatment of cancers, wanted to replace their old brachytherapy suite with a Cyberknife® and chose Calder to design, manufacture and install lead shielding. Their lead chevron rail system was used to increase the shielding of the existing bunker which was required for the new equipment. Calder completed the job in just over 7 weeks which was two weeks ahead of the original schedule.
Calder was asked to provide lead radiation shielding for Mount Vernon Cancer Centre in Middlesex for the first CyberKnife® in an NHS hospital. This project required the highest levels of radiation shielding to ensure complete elimination of any ‘shine paths’. Calder’s Chevron Rail System was chosen for the installation of the lead bunker which took just 8 weeks.
While the history of Guy’s and St. Thomas’ stretches back almost a millennium, the hospitals have a well deserved reputation for looking to the future.
Their decision to commission the building of a TomoTherapy treatment centre underlines a desire to offer the latest medical advances to its patients. Calder Industrial Materials, the European leaders in lead radiation shielding, provided a bespoke solution capable of satisfying the exacting requirements of this unique project.
Safety is paramount
Building a new high radiation unit inside the existing hospital structure presented several challenges for The Trust’s design team. Satisfying their desire to create the most pleasant treatment facility possible within the physical constraints of the site led them to Calder. Calder were asked to supply lead shielding that guaranteed operator safety and maximised available floor space.
Bespoke lead shielding
The modular design of Calder’s Chevron Rail System was perfectly suited to the limited space available at Guy’s and St. Thomas’. Working closely with the TomoTherapy® machine suppliers and QMP Consultants they developed a bespoke shielding scheme which varied overall wall thicknesses without compromising safety.
