Motion planning is a fundamental problem in robotics that involves determining feasible or optimal paths within finite time. While complete motion planning algorithms are guaranteed to converge to a path solution in finite time, they are proven to be computationally inefficient, making them unsuitable for most practical problems. Resolution-complete algorithms, on the other hand, ensure completeness only if the resolution parameter is sufficiently fine, but they suffer severely from the curse of dimensionality. In contrast, sampling-based algorithms, such as Rapidly Exploring Random Trees (RRT) and its variants, have gained the increasing attention of researchers due to their computational efficiency and effectiveness, particularly in high-dimensional problems. This review paper introduces RRT-based algorithms and provides an overview of their key methodological aspects.

Kinematic alignment is increasingly adopted in total knee arthroplasty (TKA) as a patient-specific strategy to restore native joint anatomy. However, its reliance on static radiographic measurements may not adequately reflect real-world functional biomechanics. This editorial underscores the importance of complementing static assessment with kinetic principles.

Background: Stereotactic body radiotherapy (SBRT) is an effective treatment for early-stage non-small cell lung cancer. However, patient breathing can affect treatment accuracy. Therefore, this study aimed to develop a bi-polar (BP) gated motion management strategy for SBRT and evaluate its feasibility geometrically and dosimetrically.

Background: In healthcare education, virtual reality (VR), simulating real-world situations, is emerging as a tool to improve communication skills, particularly in sensitive scenarios involving patients and caregivers. While promising, VR-based education also poses challenges such as avatar realism, cognitive load, and the need for pedagogical grounding.
Objective: This protocol paper presents the VR-TALKS project, which aims to develop, apply, and evaluate VR scenarios designed to teach healthcare students communication skills in serious illness scenarios.

Percutaneous pelvic screwing (PPS) enables fixation of traumatic or atraumatic fractures with little or no displacement, or displaced but reduced fractures, and preventive fixation of primary or secondary tumoral lesions. It is a relatively recent technique, and indications are evolving with progress in pre- and intra-operative imaging. Morbidity is lower than with open surgery.

Cardiovascular magnetic resonance (CMR) imaging is an established non-invasive tool for the assessment of cardiovascular diseases, which are the leading cause of death globally. CMR provides dynamic and static multi-contrast and multi-parametric images, including cine for functional evaluation, contrast-enhanced imaging and parametric mapping for tissue characterization, and MR angiography for the assessment of the aortic, coronary and pulmonary circulation. However, clinical CMR imaging sequences still have some limitations such as the requirement for multiple breath-holds, incomplete spatial coverage, complex planning and acquisition, low scan efficiency and long scan times.
