Article Synopsis
- The current method for assessing pedicle screw loosening relies heavily on radiation-emitting imaging, which can be unreliable in certain cases.
- The authors propose a new, radiation-free technique using vibroacoustic sensing that involves exciting the vertebrae with vibrations and measuring them with a sensitive sensor attached to the screw.
- The new method has been validated through simulations and physical tests on cadaveric lumbar spine specimens, achieving high sensitivity and specificity in detecting loose implants.
Article Synopsis
- Recent advancements in treatments for age-related macular degeneration require precise, minimally invasive delivery methods to avoid trauma to vital eye structures.
- Skilled surgeons face challenges due to hand tremors, prompting the development of robotic systems that utilize fiber Bragg grating (FBG) sensors to monitor forces during surgery.
- This paper introduces a specialized dataset combining force feedback data with optical coherence tomography (OCT) images and presents a neural network model for estimating forces based on these images, highlighting the dataset's potential use.
Structured reporting (SR) has long been a goal in radiology to standardize and improve the quality of radiology reports. Despite evidence that SR reduces errors, enhances comprehensiveness, and increases adherence to guidelines, its widespread adoption has been limited. Recently, large language models (LLMs) have emerged as a promising solution to automate and facilitate SR.

Despite advances in medical imaging technology, the information conveyance remains unimodal. This visual representation fails to capture the complexity of the real, multisensory interaction with human tissue.

Despite this, the related knowledge about widget's visual design and interactive user feedback is still limited. Therefore, this study is contributed to by co-designed MR drill tool positioning widgets with two expert dentists and three MR experts.
