Summary
The new Eclipse treatment planning module successfully creates clinically acceptable modulated arc (mARC) radiation therapy plans. These plans offer high fidelity delivery and significantly faster treatment times compared to traditional methods.
Area of Science:
- Radiation Oncology
- Medical Physics
- Radiotherapy Technology
Background:
- Siemens modulated arc (mARC) technology has been available for two years.
- Limited treatment planning system options previously existed for mARC planning.
Purpose of the Study:
- To evaluate the clinical acceptability and feasibility of the new Eclipse treatment planning module for mARC treatments.
- To compare the delivery efficiency of mARC plans with static gantry IMRT plans.
Main Methods:
- Generated 23 mARC treatment plans for diverse clinical sites using the Eclipse system.
- Assessed plan quality using a 3%/3 mm gamma pass rate.
- Created 14 equivalent static gantry IMRT plans for comparison.
- Measured and compared treatment delivery times.
Main Results:
- All 23 mARC plans were deliverable without anomaly.
- The average gamma pass rate was 98.0% (±1.7% SD), indicating high plan fidelity.
- mARC plans demonstrated significantly faster delivery times compared to static gantry IMRT in most cases.
Conclusions:
- The Eclipse mARC module successfully generates clinically acceptable and deliverable treatment plans.
- mARC planning with the Eclipse module offers potential for reduced treatment times on Siemens ARTISTE linear accelerators.

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
