Ralco collimators are not just for making great x-ray pictures in dental surgeries. They are an essential part of the equipment that treats many forms of cancer with radiotherapy. They use powerful and destructive electromagnetic energy rays like neutron and gamma radiation to penetrate patients bodies and attack cancerous tumors in as specific and targeted a way as is possible with current technology.
Thus Ralco are all about bespoke design equipment to meet the therapeutic needs of thousands of individual cancer sufferers. Electromagnetic radiation can be injurious and even fatal when people are exposed to it in an uncontrolled way. It is the function of Ralco collimators to firstly screen out much of the destructive radiation, then to allow through only those energy rays that can be concentrated into suitable doses and sent to attack the cancer tumors.
Of course the collimator must also protect the medical team operating the machine from harmful exposure to radiation. Ralco collimators are thus the target guidance systems for safe radiotherapy treatment. Of course they contain a radioactive isotope within the machine but surrounded by lead shielding. They allow only certain limited amounts of energy rays through an elaborate series of parallel plates. Radiotherapy typically involves beaming radiation from without to within the cancer sufferers body. It generally makes use of a device known as a ‘linear accelerator’.
Racol collimators are the essential part of these devices. They focus and dilute the deadly power rays of radiation into those cancerous parts of body that need ‘killing therapy’. This type of therapy is pain free and is becoming ever more free of side effects too. Radiotherapy usually takes place over a number of session separated in time over weeks. Racol expertise is central to developing this technology so as to better concentrate and guide with pinpoint accuracy these rays for use in external radiotherapy.
The therapy works in 3 ways: Firstly the rays are sent in to shrink tumors prior to an operation for physical removal of the remaining tumors. Secondly they are aimed to take out benign tumors where an operation would only cause discomfort and pain. And thirdly they are used after cancer removal operations to kill of any residual cancerous cells. For patients with incurable cancers, radiotherapy and the essential collimator technology is vital for controlling tumor progression and thus extending life while also adding to the quality of that life.
