Purpose: The purpose of this article was to highlight the importance of data management systems in radiotherapy.
Methods: We performed a database search to review the errors or potential errors in radiotherapy planning and delivery which could be prevented in case of using the DICOM communication system.
Results: We registered the following rates of errors: 1) Errors caused by manual rewriting of treatment plan 30%; 2) Errors caused by wrong assignment of the verification system 15%; 3) Errors during the manual rewriting of treatment data to the verification system 15%; 4) Patient identification 5%; 5) Field verification 15% 6) Wedge orientation 10%.
Conclusion: DICOM communication system may significantly improve the quality assurance in radiotherapy.

Division of Cardiology, The Hospital for Sick Children, Toronto, ON, Canada; Center for Image Guided Innovation and Therapeutic Intervention, The Hospital for Sick Children, Toronto, ON, Canada.
Objectives: Mixed reality (MixR) is an innovative visualization tool that presents virtual elements in a real-world environment, enabling real-time interaction between the user and the combined digital/physical reality. We aimed to explore the feasibility of MixR in enhancing preoperative planning and intraoperative guidance for the correction of various complex congenital heart defects (CHDs).
Methods: Patients underwent cardiac computed tomography or cardiac magnetic resonance and segmentation of digital imaging and communications in medicine (DICOM) images was performed.

Buccal cortical bone dimensions are crucial in dental radiology, as they impact orthodontic treatment outcomes. Changes in alveolar bone dimensions can result in malocclusion and require interdisciplinary approaches for correction. The accurate quantification of buccal bone dimensions is crucial for appropriate treatment planning and avoiding medico-legal issues.

Background: Soft tissue defects on the palm side of the thumb can be effectively covered by using the radial midpalmar (RMP) flap, which is usually harvested as a pedicled flap. However, previous anatomical studies on this flap are limited. We analyzed multidetector-row computed tomography angiograms of the radial midpalm of hands to more precisely characterize the 3-dimensional anatomical structure of the perforators in living patients.

Purpose: This study was performed to introduce, evaluate, and compare various novel assessment protocols designed for straightforward, reliable, and reproducible measurement of alveolar bone levels. These protocols are intended for standardized periodontal assessment and follow-up, utilizing cone-beam computed tomography (CBCT) images and manipulation of Digital Imaging and Communications in Medicine (DICOM) viewer software.
Materials And Methods: Two experienced oral and maxillofacial radiologists developed 5 distinct radiographic measurement protocols.
Estimating Palatal and Pharyngeal Muscle Contraction in Hindi Syllable Pronunciation using Computational Modeling.

Article Synopsis
- Speech functions impacted by cleft palate involve complex sound production from various organs, and while traditional evaluations post-surgery are subjective, this study aims to provide objective assessments by measuring muscle contractions during speech.
- A healthy volunteer underwent dynamic MRI while pronouncing Hindi syllables, allowing researchers to create 3D models of the palate and pharynx, then analyze muscle contractions using a finite element model for different sounds.
- Results showed varying contraction levels for the palate and pharyngeal wall with different syllables, with the highest contractions for the syllable /k/ and the potential to use this data to quantify speech issues and evaluate surgical effectiveness in larger populations.
