Adaptive filtering of temporally varying X-ray image sequences acquired during endovascular interventions can improve the visual tracking of catheters by radiologists. Existing techniques blur the important parts of image sequences, such as catheter tips, anatomical structures and organs; and they may introduce trailing artifacts. To address this concern, an adaptive filtering process is presented to apply temporal filtering in regions without motion and spatial filtering in regions with motion… 

Mapping spatio-temporal filtering algorithms used in fluoroscopy to single core and multicore DSP architectures

The paper explains the fixed point design of these algorithms, which are mapped onto the C64x+TM core using instruction-level parallelism to effectively use its VLIW architecture and distributes the operations to leverage multi-core DSP architectures.

Curvelet Based Contrast Enhancement in Fluoroscopic Sequences

Quantitative and qualitative evaluations performed on synthetic and real low-dose sequences demonstrate that the proposed denoising method enables a 50% dose reduction and a line enhancement technique in the curvelet domain is proposed.

A device enhancing and denoising algorithm for X-ray cardiac fluoroscopy

This article proposes an algorithm based on spatial-temporal filtering conditioned by a feature of interest map that will either filter, preserve or enhance the image content in the denoising of fluoroscopic image sequences in interventional cardiology.

A comparison of line enhancement techniques: applications to guide-wire detection and respiratory motion tracking

This article reviewed and classified guide-wire detection techniques into three families and built a rigorous framework to compare their detection capability and their computational complexity, demonstrating that the Hessian based methods are the most robust to strong curvature of the devices and that the family of rotated filters technique is the most suited for detecting low CNR and low curvature devices.

Image processing algorithms for the visualization of interventional devices in X-ray fluoroscopy

The objective of the work presented in this thesis is designing, studying and validating image processing techniques that improve the visualization of stents and proposes a generic tool to process such curvilinear structures that is called the Polygonal Path Image (PPI), which relies on the concept of locally optimal paths.

X-ray fluoroscopy spatio-temporal filtering with object detection

A new filtering method, spatio-temporal filtering with object detection, is described that reduces noise while minimizing motion and spatial blur, and is demonstrated on several representative X-ray fluoroscopy sequences.

Quantitative image quality of spatially filtered x-ray fluoroscopy

In both single image frames and image sequences, the effect of noise-reduction spatial filtering on the detection of stationary cylinders that mimicked arteries, catheters, and guide wires in x-ray imaging is investigated, concluding that edge-preserving spatial filtering is more effective in sequences than in single frames.
