Results: No statistically significant correlation was found for age, gender and ΔW. was found to have clinically important correlation with functional MDADI (ρ = −0.39, P = 0.081). ΔVROI was found to have statistically significant correlation of 0.44, 0.47 and 0.44 with global, physical and functional MDADI (P-value < 0.05). Δϕn was found to have statistically significant ranked-correlation (−0.46, −0.46 and −0.45) with physical, functional and total MDADI (P-value < 0.05). Conclusion: A transit fluence based decision support metric (DSM) is statistically correlated with the dysphagia risk. It can not only be used as an early signal in assisting clinicians in the ART patient selection for replanning, but also lowers the resource barrier of ART implementation.]]> Wed 21 Sep 2022 11:32:28 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38849 P = 0.65).

The 2D → 3D target position estimation was based on a probability distribution function. The 3D → 6DoF target rotation was calculated using an iterative closest point algorithm. The accuracy and precision of the KIM method was measured by comparing the real-time results with kV-MV triangulation. Results: Of the five treatment fractions, KIM was utilised successfully in four fractions. The intrafraction prostate motion resulted in three couch shifts in two fractions when the prostate motion exceeded the pre-set action threshold of 2 mm for more than 5 s. KIM translational accuracy and precision were 0.3 ± 0.6 mm, −0.2 ± 0.3 mm and 0.2 ± 0.7 mm in the Left-Right (LR), Superior-Inferior (SI) and Anterior-Posterior (AP) directions, respectively. The KIM rotational accuracy and precision were 0.8° ± 2.0°, −0.5° ± 3.3° and 0.3° ± 1.6° in the roll, pitch and yaw directions, respectively. Conclusion: This treatment represents, to the best of our knowledge, the first time a cancer patient’s tumour position and rotation have been monitored in real-time during treatment. The 6 DoF KIM system has sub-millimetre accuracy and precision in all three translational axes, and less than 1° accuracy and 4° precision in all three rotational axes.]]> Thu 24 Mar 2022 11:35:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38728 Thu 20 Jan 2022 13:36:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34741 Thu 17 Feb 2022 09:29:26 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38715 Mon 20 Nov 2023 15:50:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43841 Mon 20 Nov 2023 14:35:06 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55076 Mon 08 Apr 2024 14:17:28 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46392 Fri 25 Nov 2022 13:59:19 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46579 Fri 25 Nov 2022 13:39:41 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51930 Fri 22 Sep 2023 11:07:30 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51889 Fri 22 Sep 2023 09:22:44 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51888 Fri 22 Sep 2023 09:22:04 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52691 Fri 20 Oct 2023 15:54:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51078 Fri 18 Aug 2023 09:31:56 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51714 Fri 15 Sep 2023 17:46:38 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39998 Fri 15 Jul 2022 11:01:56 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40333 Fri 08 Jul 2022 09:44:37 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51352 , per tangent were compared to the planned mLDs; differences between the largest and smallest observed () per tangent were calculated. Results: For 56% (162/288) of the tangents tested, were outside the tolerance window. All but one patient had at least one fraction showing this behaviour. The largest difference found between an and its planned mLD was −16.9 mm. The accuracy of patient positioning and the quality of marker-block-based DIBH guidance contributed to the differences. Fractions with patient position verification using a single EPID image taken before treatment showed a lower rate (34%), suggesting reassessment of setup procedures. Conclusions: Real-time treatment monitoring of the internal anatomy during DIBH delivery of tangential breast RT is feasible and useful. The new system requires no additional radiation for the patient.]]> Fri 01 Sep 2023 13:36:10 AEST ]]>
