Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA For unstable patients requiring urgent administration of medications, fluids, or blood products, establishing vascular access quickly is essential. However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A tension pneumothorax is a life-threatening situation in which excess air is introduced into the pleural space surrounding the lung, either through trauma to the chest cavity or as a spontaneous leak of air from the lung itself. Air trapped within the pleural space causes separation of the lung from the chest wall, disrupting normal breathing mechanisms. Pneumothorax may be small without...

We describe here a protocol for microinjection in the rodent brain that uses quartz needles. These needles do not produce detectable tissue damage and ensure reliable delivery even in deep regions. Moreover, they can be adapted to research needs by personalized designs and can be re-used.

Optical coherence tomography (OCT) is a high resolution imaging technique that allows analysis of tissue specific optical properties providing the means for tissue differentiation. We developed needle based OCT, providing real-time imaging combined with on-the-spot tumor differentiation. This publication describes a method for percutaneous, needle based OCT of renal masses.
FAQs
A reference frame gives the localized needle tip a consistent spatial context. The system can express the tip’s position and orientation as coordinates relative to the workspace or target, rather than treating measurements as isolated observations. This conversion supports trajectory planning, obstacle avoidance, and controlled placement because robotic or image-guided systems can compare the tip location with desired geometric positions.
Needle Tip Localization can combine visual features, electromagnetic signals, tracked motion, and geometric modeling to obtain information about the distal tip. These inputs provide different forms of spatial evidence that can be processed and converted into coordinates. Combining sensing with modeling helps an engineering system represent the tip’s position and orientation for steering, insertion, or inspection tasks.
Accuracy depends on how effectively the system captures relevant visual, electromagnetic, or motion information and converts it into spatial coordinates. The relationship between the needle, workspace, and reference frame also matters because errors in that relationship can affect the reported position or orientation. Improving these localization steps can increase repeatability and support more consistent needle placement.
A general workflow begins by acquiring information through imaging, sensing, or tracked motion. The system then identifies relevant features or measurements, applies geometric modeling or signal processing, and expresses the distal tip relative to a reference frame. The resulting position and orientation can be compared with a target or planned path, supporting subsequent steering, insertion, or verification.
Engineers apply Needle Tip Localization when a system must guide, monitor, or verify needle placement. Relevant uses include robotic needle steering, minimally invasive interventions, automated insertion, and image-guided procedures. By supplying the tip’s spatial location and orientation, localization helps these systems plan trajectories, avoid obstacles, and place the needle at a specified location.
Localization provides a way to assess whether the needle tip follows an intended path or reaches the specified location. In quality control, this information can support checks of placement consistency and repeatability. In image-guided or minimally invasive procedures, spatial awareness can help systems avoid obstacles and improve targeting accuracy, contributing to safer and more controlled operation.
