Abstract
Cancer has become the number one cause of death in Canada and lung cancer is its deadliest form. Surgical resection remains as the treatment of choice for most patients; however, in many cases a less aggressive alternative such as brachytherapy may be preferable. Today, HDR brachytherapy is a relatively common procedure but with current techniques and equipment only tumours close to the main bronchi can be reached.
This project describes the design, development and validation of a first prototype of an ultrasound-guided needle guidance system that would enable physicians to perform HDR brachytherapy for the treatment of lung cancer in a minimally invasive manner through the intercostal spaces. The development of the mechanical components is thoroughly described followed by the description of the electronic control system that was developed for this novel mechatronic medical tool. Finally through validation experiments, the approach was shown to be an accurate and viable approach for precisely reaching desired targets with a wide yet flexible needle.
