External dacryocystorhinostomy: Tips and tricks

Oman Journal of Ophthalmology, 2012
Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium.

A CT-guided Control Framework of a Robotic Flexible Endoscope for the Diagnosis of the Maxillary Sinusitis [PDF]

arXiv
Flexible endoscopes are commonly adopted in narrow and confined anatomical cavities due to their higher reachability and dexterity. However, prolonged and unintuitive manipulation of these endoscopes leads to an increased workload on surgeons and risks of collision.

A novel terahertz time-domain spectroscopic endoscope based on a single photoconductive antenna chip [PDF]

arXiv, 2013
The common terahertz time-domain spectroscopy (THz-TDS) based on photoconductive antenna (PCA) needs two separate PCA chips. One PCA works as an emitter, and the other works as a receiver. For a reflection-type measurement, the technique called 'attenuated total reflection' usually is needed to enhance the reflection sensitivity.

BrightVAE: Luminosity Enhancement in Underexposed Endoscopic Images [PDF]

arXiv
The enhancement of image luminosity is especially critical in endoscopic images. Underexposed endoscopic images often suffer from reduced contrast and uneven brightness, significantly impacting diagnostic accuracy and treatment planning. Internal body imaging is challenging due to uneven lighting and shadowy regions.
