A new, easily miniaturized steerable endoscope

A miniaturized fiber-coupled terahertz endoscope system.

In this study, we have designed, fabricated, and characterized a miniaturized optical fiber-coupled terahertz (THz) endoscope system. The endoscopic system utilized a photoconductive generator and detector driven by a mode-locked Ti:sapphire laser. In reflection mode, the endoscope showed a high signal-to-noise ratio and a wide frequency spectrum similar to the conventional THz time-domain spec...

Development of miniaturized light endoscope-holder robot for laparoscopic surgery

PURPOSE We have conducted experiments with an innovatively designed robot endoscope holder for laparoscopic surgery that is small and low cost. MATERIALS AND METHODS A compact light endoscope robot (LER) that is placed on the patient's skin and can be used with the patient in the lateral or dorsal supine position was tested on cadavers and laboratory pigs in order to allow successive modifica...

A New 3 D Orientation Steerable FilterWei

A new type of eye endoscope.

OuR knowledge of the interior of the eye has been greatly advanced by the use of the ophthalmoscope, slit lamp, and gonioscope, but the region about and forward from the ora serrata remains invisible. Therefore the nature of any pathological process must be deduced indirectly from its effect on the lens, vitreous, and retina, or by transillumination. A new endoscope has therefore been devised w...

Miniaturized Phased-Array Ultrasonic Endoscope Initial Experience With Intracardiac Imaging in Piglets

Background. Recent advances in miniaturization of phased-array and mechanical ultrasound devices have resulted in exploration of alternative approaches to cardiac and vascular imaging in the form of transesophageal or intravascular imaging. Preliminary efforts in adapting phased-array endoscopes designed for transesophageal use to a transvascular approach have used full-sized phased-array devic...
