Controller Assists in Targeting Cancerous Tumors with Precision
Rocklin, CA- February 14, 2008-Galil Motion Control's integrated DMC-2153 5-axis controller is now being used in TomoTherapy Incorporated's Hi-Art® treatment system, a focused radiation therapy device that targets cancerous tumors without harming the surrounding healthy tissue. The device results in more effective treatment deliveries, with minimized side effects.
The revolutionary machine, designed to leverage the ring gantry geometry used in CT scanning, integrates optimized planning, image-guidance and helical delivery to provide precise, continuous intensity-modulated radiation therapy (IMRT) from all angles around a cancer patient.
Galil's DMC-2153 5-axis controller handles the X-Y-Z motion of the patient couch, which slides into the gantry. Galil's controller places the couch to within +/-1mm accuracy, and TomoTherapy is moving toward sub-millimeter accuracy in future models.
"We considered several motion controllers for the Hi-Art® system and Galil's controller met our requirements for its Ethernet-based control of stepper and servo motors, ability to multitask, SSI feedback capability and robust programming language," said Graham Reitz, TomoTherapy Research Engineer. "It had to be small enough to fit in our very small, allowed space."
The DMC-2153 precisely controls the Z-axis for handling the "Up/Down" motion of the couch. An integrated motor and stepper driver work in concert with the DMC-2153 to control the Y-axis for moving the couch in and out of the bore, and the X-axis for right/left lateral movements. The DMC-2153 controller also accepts two forms of feedback, incremental and SSI absolute, to "double check" and maintain the couch position should there be any disruption due to power loss, and to ensure precise synchronization of the X-Y axis. To accommodate TomoTherapy's needs, Galil customized the controller so it could easily accept all of the SSI devices for feedback.
TomoTherapy has over 150 Hi-Art® treatment systems installed at clinics around the world, treating tumors that result in prostate cancer, lung metastasis, scalp carcinoma, multiple lesions and more.
