We are developing a dynamic adaptive exposure technique using our scanning beam digital X-ray system. Rather than exposing an object uniformly, the exposure is adapted depending on the opacity of the object. Here we show an experiment on an anthropomorphic phantom that resulted in a dose saving of 30%.

Here, we present a protocol for live imaging of mouse secondary palate fusion using confocal microscopy. This protocol can be used in combination with a variety of fluorescent reporter mouse lines, and with pathway inhibitors for mechanistic insight. This protocol can be adapted for live imaging in other developmental systems.

2025
This video describes a method to visualize the assembly of fusion protein condensates on DNA molecules at specific loci using single-molecule imaging. These condensates are formed due to LCD-LCD and LCD-DBD interactions, which allow for the recruitment of RNA polymerase II and enhanced gene transcription.

Nuclear Fusion

The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons. A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...
FAQs
Registration links the previously acquired three-dimensional dataset to the patient, then aligns that dataset with the fluoroscopic view. This correspondence lets clinicians interpret the real-time X-ray image against the patient’s relevant anatomy rather than viewing each image source independently. The result is a spatially coordinated display for navigation, device placement, or lesion treatment decisions.
The three-dimensional dataset and fluoroscopy differ in how and when they depict anatomy. Fusion addresses these differences by registering the prior dataset to the patient and aligning it with the current fluoroscopic view. This relationship allows previously captured anatomical information to remain useful while clinicians monitor real-time device movement and procedural progress.
Fluoroscopy provides real-time X-ray information but limited two-dimensional anatomical context. Adding the registered three-dimensional dataset helps clinicians understand the spatial relationships among target structures, vessels, and devices. That added orientation can make catheter navigation, device placement, and lesion treatment easier to interpret than relying on the fluoroscopic view without corresponding three-dimensional information.
A typical workflow begins with a previously acquired three-dimensional study, such as CT. The dataset is registered to the patient, and the system aligns it with the fluoroscopic view. During the procedure, clinicians use the combined display to relate real-time X-ray findings to anatomy while navigating catheters, placing devices, or treating a lesion.
Fluoroscopic image fusion supports procedures in interventional radiology, cardiology, and surgery. Its applications include catheter navigation, device placement, and lesion treatment. In each setting, the fused view supplies anatomical context alongside real-time fluoroscopy, helping clinicians maintain spatial orientation while working with targets, vessels, or devices that may be difficult to interpret from two-dimensional imaging alone.
The combined display helps clinicians relate a moving device or catheter to registered anatomical structures, vessels, and treatment targets. It can also support procedural planning by showing how limited two-dimensional fluoroscopic information corresponds to a broader three-dimensional representation. These capabilities strengthen spatial interpretation and help guide decisions during navigation, placement, and lesion treatment.
