The increased distance between surgeon and surgical field is a significant problem in laparoscopic surgery. Robotic surgery, although providing advantages for the operator, increases this gap by completely removing force feedback. Enhancement with visual tools can therefore be beneficial. The goal of this preliminary work was to create a custom plugin for OsiriX to display volume-rendered images in the da Vinci surgeon's console. The TilePro multi-input display made the generated stereoscopic pairs appear to have depth. Tumor position, vascular supply, spatial location, and relationship between organs appear directly within the surgeon's field of view. This study presents a case of totally robotic right colectomy for cancer using this new technology. Sight diversion was no longer necessary. Depth perception was subjectively perceived as profitable. Total immersion in the operative field helped compensate for the lack of tactile feedback specific to robotic intervention. This innovative tool is a step forward toward augmented-reality robot-assisted surgery.

Computed tomography plays an ever-increasing role in the management of fractures and dislocations due to its capability in efficiently providing multiplanar reformats and 3-dimensional volume rendered images. It can reveal findings that are occult on plain radiography and therefore allow for more accurate decision making with regard to fracture classification and management. Clinical radiologists play a critical role in facilitating the processing of imaging to provide adequate image reformats in the desired planes, producing 3 dimensional images but most crucially identifying pertinent findings, which will contribute between the selection of nonoperative and operative management and potentially influence surgical technique.

Objectives: Photon-counting detector CT (PCD-CT) is expected to substantially improve and expand CT-imaging applicability due to its intrinsic spectral capabilities, increased spatial resolution, reduced electronic noise, and improved image contrast. The current study aim is to evaluate PCD-CT efficacy in characterizing bullets based on their dimensions, shape, and material composition.
Materials And Methods: This is an observational phantom study examining 11 unfired, intact bullets of various common calibers, placed in ballistic gelatin.

Jurors rely on evidence presented in court to find the facts of a case. Consequently, the manner in which evidence is delivered may significantly impact the extent to which jurors comprehend and interpret the evidence. Building on a pilot study, the aim of this research was to further investigate which format for presenting forensic medical evidence in court was best for laypersons (i.

Introduction: Birefringent crystals such as monosodium-urate (MSU) and cholesterol crystals (CC) likely contribute to the progression of coronary artery disease (CAD) due to their potential to exacerbate inflammation through inflammatory cytokine activation. Here, we present cross-polarized micro-optical coherence tomography (CP-µOCT) for visualizing individual birefringent crystals in human coronary arteries.
Methods And Results: Human cadaver coronary arteries with a history of CAD with or without gout were dissected for CP-µOCT imaging.
The 'DIMPLE SIGN' of Intra-Aortic Cord.

Background: With increasing use of imaging to diagnose human pathology, newer aortic anomalies are being identified. An intra-aortic cord is one such abnormality, which requires differentiating from an intimal flap of dissection, to avoid major surgery or prolonged surveillance. The aim of this study was to bring forth a unique feature of the intra-aortic cord on imaging, using volume rendering reformatting and identify similar findings in published literature and hence establish the role of the 'Dimple' sign.
