For lung, breast, liver and pancreas treatments

 

 

The SDX is a breathing control system for radiotherapy that enables the reproducible positioning of the tumour from medical imaging through to the final session of treatment, limiting excessive irradiation of healthy tissues and contiguous organs.

 

Ergonomic and equipped with intuitive software, the SDX is designed for easy handling by radiotherapy professionals. Today, the SDX is used routinely in over 100 radiotherapy centres worldwide.

CT Scanning & Treatment Planning 

 

After training, the patient proceeds to the CT scanner for treatment planning imaging. With the use of the video goggles, the patient is able to visualize the target inspiration zone. CT images are taken while the patient performs the breath hold, thereby reducing artifacts. SDX with DIBH decreases the movement of organs within the thoracic cavity, allowing for enhanced tumor imaging and visualisation. The acquired CT images are used to develop the treatment plan.

Treatment

 

During each radiotherapy session, the patient produces several breath holds, lasting from a few to approximately 20 seconds. The use of video goggles provides bio-feedback to the patient indicating when and for how long to produce the breath hold. 95% of patients are able to master this method, regardless of the respiratory pathology from which they suffer. The patient’s active involvement is an important motivating factor contributing to successful completion of the treatment cycle. 

The Voluntary Breath Hold Method

 

During the initial preparation phase, the patient learns to use the spirometer, and the clinical team determines the optimal breath hold level according to the patient’s respiratory capacity. The patient is then asked to voluntarily reproduce the breath holds at the same pulmonary volume level during each subsequent medical imaging and radiotherapy session.
