Summary
This study developed a miniature forward-viewing spectrally encoded endoscopy (SEE) probe, achieving high spatial resolution and a wide field of view for enhanced medical imaging and navigation.
Area of Science:
- Optical Imaging
- Medical Device Development
- Endoscopy
Background:
- Spectrally encoded endoscopy (SEE) uses spatial wavelength multiplexing for miniature probes.
- Forward-viewing SEE probes offer advantages in navigation and surveillance over side-viewing devices.
- Existing SEE devices require further development for improved visualization capabilities.
Purpose of the Study:
- To develop a miniature, forward-viewing SEE probe.
- To achieve a wide field of view and high spatial resolution.
- To enhance visualization and navigation in medical imaging.
Main Methods:
- Designed and developed a 1.27mm diameter forward-viewing SEE device.
- Incorporated a monolithic illumination probe, 8 detection fibers, and a rotational scanning mechanism.
- Evaluated probe resolution using a USAF target and performed preclinical imaging of a swine joint.
Main Results:
- Achieved a best spatial resolution of 20.3µm.
- Obtained a wide total angular field of view of 100°.
- Demonstrated superior spatial resolution and field of view compared to a commercial endoscope.
Conclusions:
- The developed forward-viewing SEE probe shows significant potential for medical imaging.
- The probe facilitates enhanced visualization and navigation in various medical applications.
- This technology advances the capabilities of endoscopic imaging.

01:19Encoding
777
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

01:27Cranial Bones: Lateral View
4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:24Revisionist Views of Adolescent and Adult Cognition
294
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

01:14Cranial Bones: Superior and Posterior View
5.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

1.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
