February 1, 2023 — Radiotherapy is a crucial component of cancer treatment, used to shrink or destroy tumors with high-energy radiation. However, the success of these treatments depends on the accuracy of the dose delivered to the patient. This is why the secondary calculation of monitor units (MU) in radiotherapy is so important to ensuring patient safety.
Monitor units are used to control the amount of radiation delivered to the patient during treatment. They must be calculated correctly to ensure that the dose delivered is precisely what was intended in the treatment plan. Unfortunately, human error can sometimes occur in the calculation of monitor units, which is why the secondary calculation is so crucial.
This is where the Brazilian startup RT Medical Systems comes in. They have developed the first cloud software for secondary calculation of monitor units in Latin America. This innovative solution offers healthcare providers an additional layer of safety, by independently checking treatment plans before they are delivered to the patient.
The importance of secondary dose verification in radiotherapy cannot be overstated. There are numerous international standards and regulations in place to ensure that every treatment plan undergoes independent verification. For example, the American Association of Physicists in Medicine (AAPM) and the International Commission on Radiation Units and Measurements (ICRU) provide guidelines for ensuring that the correct dose of radiation is delivered to the patient. In Brazil, the National Commission of Nuclear Energy (CNEN) also has strict standards in place to ensure the safe delivery of radiotherapy treatments.
By using the latest technology and cloud computing, RT Medical Systems is able to provide an additional level of safety in radiotherapy treatments. The cloud-based solution allows healthcare providers to access the latest software updates and security features, without having to invest in new hardware. This makes it easier for them to comply with the strict regulations and standards required in the field of radiotherapy.
"Our software offers healthcare providers a more secure and reliable solution for secondary dose verification in radiotherapy," says CEO Carlos Queiroz. "We are proud to be leading the way in Latin America, providing innovative solutions that make a real difference in the lives of patients."
The secondary calculation of monitor units is just one of the many important steps in ensuring the safe and accurate delivery of radiotherapy treatments. However, it is a crucial one, and the cloud-based solution provided by RT Medical Systems is helping to raise the standard of care for patients undergoing radiotherapy in Latin America.
"At RT Medical Systems, our focus is always on providing the best possible solutions for our customers," says Medical Physicist CTO Pedro Argolo Piedade. "We believe that by using the latest technology and cloud computing, we can help healthcare providers deliver safer and more effective radiotherapy treatments to their patients."
As the company expands into new markets, they are committed to helping healthcare providers deliver the best possible care to their patients. Their innovative solutions and commitment to patient safety are helping to make a real difference in the lives of those undergoing radiotherapy treatment.
