Shadow-free motorized capsule enables accurate beam positioning and sectorized OCT imaging of the esophagus Open
In this study, we demonstrate a 12x36 mm motorized capsule for OCT imaging of the esophagus. The capsule produces unobstructed images by using a distal reflector design, thus avoiding shadow caused by the motor wires. The motor synchronous…

Motorized capsule for shadow-free OCT imaging and synchronous beam control Open
We demonstrate a tethered motorized capsule for unobstructed optical coherence tomography (OCT) imaging of the esophagus. By using a distal reflector design, we avoided the common shadow artifact induced by the motor wires. A synchronous d…

Real-time volumetric lipid imaging in vivo by intravascular photoacoustics at 20 frames per second Open
Lipid deposition can be assessed with combined intravascular photoacoustic/ultrasound (IVPA/US) imaging. To date, the clinical translation of IVPA/US imaging has been stalled by a low imaging speed and catheter complexity. In this paper, w…
