What is eclipse EHR?
ECLIPSE® Chiropractic EHR, Billing, and Practice Management Software Chiropractic EHR, Billing, and Practice Management Software ECLIPSE is an ONC certified Complete EHR licensed to over 37,000 users across more than 7,000 Chiropractic, Physical Therapy, and Medical facilities throughout the United States on their LAN’s & in the cloud.
Why choose eclipse®?
And since every facet of ECLIPSE was developed by our programming team, billing, scheduling, history, SOAP, document imaging, and other features all work together seamlessly. ECLIPSE® has repeatedly topped independent surveys by multiple state associations.
How do I sort my eclipse structure templates by id?
By setting up your Eclipse Structure Templates with a numerical ID at the beginning of each target structure name, your structures will automatically be sorted to the top of the structure list. Each PTV should then be matched with a corresponding dose evaluation region structure created by adding a ~1 cm margin to the PTV (eg. zGI_1).
2-for-1 Contouring
Contouring femur takes a long time in prostate planning, as most of the automated tools are unable to properly separate out the correct bony anatomy. However, it is possible to save time by exploiting the symmetry of the left and right femur by using the Transform Structure and Flip Horizontal tools in Eclipse.
Minimizing Dose Spill Outside of the PTV
For dose spill constraints, it is beneficial to create a ~1 cm rind surrounding your target to minimize high dose spill outside of the PTV. Use the Extract Wall contour tool with outer margin = 1.0 and inner margin = -0.1 to create a rind structure that can be pushed in the optimizer to minimize dose spill.
Contouring Tips for Brain SRS
Controlling and evaluating the conformity index and dose fall-off for multiple lesion brain SRS planning can pose a significant challenge to planners. Ensuring quality and consistency for these cases becomes increasingly difficult and time consuming as the number of targets rises.
Tangent Breast Evaluation
Traditional tangent breast planning rarely required the evaluation of DVH coverage. However, as planning systems became more sophisticated and protocols required consistency among these plans, it has become necessary to contour the breast tissue as a target for plan evaluation.
Abstract
Implementing tighter intensity modulated radiation therapy (IMRT) quality assurance (QA) tolerances initially resulted in high numbers of marginal or failing QA results and motivated a number of improvements to our calculational processes. This work details those improvements and their effect on results.
1 INTRODUCTION
The clinical relevance of intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) quality assurance (QA; further referred to as IMRT QA) is often questioned 1 - 4 due to the lack of sensitivity of the IMRT QA methods.
2 MATERIALS AND METHODS
One hundred eighty plans, 101 head and neck and 79 prostate VMAT/IMRT (further referred to as IMRT) plans analyzed in the preceding year were collected.
3 RESULTS
The retrospective analysis of IMRT QA results showed that all head and neck and prostate plans would have passed the 95% threshold using the original gamma criteria. However, when the new gamma criteria were applied, the gamma passing rate distribution spread out as shown in Figs. 4 and 5.
4 DISCUSSION
This work confirmed the expectation that tightening IMRT QA tolerance levels, as recommended by AAPM TG-218 5 and validated by Stambaugh, 6 would result in many more QA results being deemed questionable or failing. Indeed, prior to implementing the revised QA parameters, it was exceedingly rare in our institution for a plan to fail IMRT QA.
5 CONCLUSIONS
Tightening IMRT QA tolerances revealed the need to improve several elements of our IMRT and VMAT calculations. As a consequence, the accuracy of our treatment planning has improved, and the frequency of finding marginal or failing IMRT QA results, while much larger than before the tightening, remains within our practical ability to respond.
