High temporal and spatial resolution imaging of peripheral vascular malformations

Pretreatment imaging of peripheral vascular malformations

Peripheral vascular malformations (VMs) are complex and diverse vascular lesions which require individualized pretreatment planning. Pretreatment imaging using various modalities, especially magnetic resonance imaging and time-resolved magnetic resonance angiography, is a valuable tool for classifying peripheral VMs to allow proper diagnosis, demonstrate complete extent, identify the nidus, and...

High temporal resolution imaging of spatial working memory

A substantial literature examining the neural correlates of workingmemory using functional magnetic resonance imaging (fMRI) has revealed the involvement of a predominantly fronto–parietal network in the maintenance and manipulation of information in working memory. However, the temporal dynamics of activity in this system cannot be revealed by fMRI at the sub-second level. We employed magnetoe...

Photoacoustic lymphatic imaging with high spatial-temporal resolution.

Despite its critical function in coordinating the egress of inflammatory and immune cells out of tissues and maintaining fluid balance, the causative role of lymphatic network dysfunction in pathological settings is still understudied. Engineered-animal models and better noninvasive high spatial-temporal resolution imaging techniques in both preclinical and clinical studies will help to improve...

Photoplethysmographic imaging of high spatial resolution

We present a new method of formation photoplethysmographic images with high spatial resolution from video recordings of a living body in the reflection geometry. The method (patent pending) is based on lock-in amplification of every pixel of the recorded video frames. A reference function required for synchronous detection of cardiovascular pulse waves is formed from the same frames. The method...
