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
As thorough treatment can only start with well-defined medical images, at Amethyst, we rely on high-precision imaging systems. Planning bases upon magnetic resonance imaging (MRI), computed tomography (CT), or occasionally PET scans have the potential to uncover disease characteristics that fail to be appreciated by the naked eye, hence contributing to more accurate diagnosis and better treatment decisions. This imaging is required to determine the exact size, shape, and position of the target.
The treatment planning system is at the heart of radiation therapy and key to improving patient outcomes. Amethyst uses a specially designed computer system to calculate a precise and accurate treatment plan based upon a patient’s magnetic resonance imaging (MRI), computed tomography (CT), or PET scans.
The treatment planning system supports the most advanced treatment techniques, such as stereotactic VMAT. It offers Pareto Mode optimization with Monte Carlo fast computation performance, enabling our physicists and doctors to find the best and unique patient’s plan.
This treatment method is well-established, efficient, and generally reliable. It works by delivering one or more beams of high-energy X-rays to a patient’s tumour, which damages the genetic structure of cancer cells and prevents them from spreading. As a non-invasive therapy, radiotherapy allows precise targeting of cancer cells.
The beams are generated externally by a medical linear accelerator, or Linac, which targets the tumour site with precision. This large machine can rotate around the patient during treatment, directing radiation from multiple angles to focus effectively on the tumour while minimising exposure to surrounding healthy tissues.
Advanced radiotherapy techniques aim to maximize the radiation dose that the tumor gets while minimizing the amount of radiation received by healthy tissues surrounding cancer.
The duration of radiation therapy depends on the type of tumor being treated and whether radiation therapy aims to treat cancer or ease symptoms. Usually, external beam radiation is given to patients across several sessions spread out over time (several weeks), allowing healthy cells to recover between radiation therapy sessions.
In-Vivo Monitoring verifies and tracks the dose throughout the treatment course. i.e., patient set up, first fraction, and intra-fraction motion against the treatment plan and each delivered fraction, either on the planning CT or daily CBCT images. Results can be analyzed in 3D using EPID and/or Log File data or in 2D through the Transit Dosimetry feature, with no additional time or effort required. Using calibrated EPID data, actual dosimetric In-Vivo Monitoring is clinically feasible, creating a fully independent absolute dosimetric QA of patient treatments.
