Each patient is unique and their treatment plans are too
The possibility to deliver treatment in a shorter timespan allows greater patient comfort
Designed to ensure high quality, conformal treatment plans
Effective treatment begins with accurately defined medical images. At Amethyst, we utilise high-precision imaging systems to ensure this critical foundation. Our planning relies on magnetic resonance imaging (MRI), computed tomography (CT), or occasionally PET scans. These technologies can reveal disease characteristics that are not visible to the naked eye, thereby contributing to a more precise diagnosis and improved treatment decisions. Such imaging is essential to accurately determine the exact size, shape, and position of the target.
The treatment planning system is central to radiation therapy and crucial for enhancing patient outcomes. At Amethyst, we employ a specially designed computer system to calculate precise and accurate treatment plans based on a patient’s magnetic resonance imaging (MRI), computed tomography (CT), or PET scans.
This system supports the most advanced treatment techniques, including stereotactic VMAT. It features Pareto Mode optimization with Monte Carlo fast computation performance, enabling our physicists and doctors to develop an optimal and personalized treatment plan for each patient.
This treatment method is well-established, efficient, and generally reliable. It operates by directing one or more beams of high-energy X-rays at the patient’s tumour, effectively damaging the genetic structure of cancer cells to prevent their proliferation. As a non-invasive therapy, radiotherapy ensures precise targeting of cancer cells.
The beams are produced externally by a medical linear accelerator, commonly known as a Linac, which precisely targets the site of the tumour. This sophisticated equipment can rotate around the patient during treatment, enabling radiation to be directed from multiple angles. This strategic approach focuses intensively on the tumour while minimising exposure to adjacent healthy tissues, enhancing both safety and effectiveness.
Advanced radiotherapy techniques are designed to optimise the radiation dose delivered to the tumour while minimising exposure to the surrounding healthy tissues.
The duration of radiation therapy varies based on the type of tumour being treated and the specific goals of the treatment—whether to eradicate cancer or alleviate symptoms. Typically, external beam radiation is administered over multiple sessions spanning several weeks. This schedule allows healthy cells time to recover between sessions.
In-Vivo Monitoring continuously verifies and tracks the radiation dose throughout the treatment course. This includes monitoring the patient setup, the initial treatment fraction, and intra-fraction motion against the treatment plan for each delivered fraction. This is achieved either on the planning CT or daily CBCT images. Analysis of results can be performed in 3D using EPID and/or Log File data, or in 2D through the Transit Dosimetry feature, all without requiring additional time or effort. Utilising calibrated EPID data, actual dosimetric In-Vivo Monitoring is clinically viable, providing a fully independent and absolute dosimetric QA for patient treatments.
