Optical spectroscopy has been intensively studied for cancer management in the past two decades. This review paper first introduces the background of optical spectroscopy for cancer management, which includes the advantages of optical techniques compared to other established techniques, the principle of optical spectroscopy and the typical setup of instrumentation. Then the recent progress in o...

The greatest burden of surgical disease exists in low- and middle-income countries, where the quality and safety of surgical treatment cause major challenges. Securing necessary and appropriate medical supplies and infrastructure remains a significant and under-recognised limitation to providing safe and high-quality surgical care in these settings. The majority of surgical instruments are sold...

BACKGROUND AND OBJECTIVES Few standardized testing procedures exist for instruments intended for Natural Orifice Translumenal Endoscopic Surgery. These testing procedures are critical for evaluating surgical skills and surgical instruments to ensure sufficient quality. This need is widely recognized by endoscopic surgeons as a major hurdle for the advancement of Natural Orifice Translumenal En...

For ease of use and to aid precision, left-handed instruments are invaluable to the left-handed surgeon. Although they exist, they are not available in many surgical centres. As a result, most operating theatre staff (including many left-handers) have little knowledge of their value or even application. With specific reference to cardiac surgery, this article addresses the ways in which they di...

The Northwest Society for Classical Studies (NWCS) was honored and privileged to have Professor Larry Bliquez speak on one of his favorite topics, the surgical instruments found in classical archeological sites and described in classical literature. Professor Bliquez is a distinguished and popular University of Washington professor, trained in classical (Latin and Greek) philology, winner of th...

In radiosurgery, a moving beam of radiation acts as an ablative surgical instrument. Conventional systems for radiosurgery use a cylindrical radiation beam of fixed cross section. The radiation source can be moved only along simple, standardized paths. A new radiosurgical system based on a six-degree-of-freedom robotic arm has been developed to overcome limitations of conventional systems. We a...

Raman spectroscopy has proved to be a very useful technique in astrobiology research. Especially, working with mobile instrumentation during fieldwork can provide useful experiences in this field. In this work, we provide an overview of some important aspects of this research and, apart from defining different types of mobile Raman spectrometers, we highlight different reasons for this research...

Initially, Raman spectroscopy was a specialized technique used by vibrational spectroscopists; however, due to rapid advancements in instrumentation and imaging techniques over the last few decades, Raman spectrometers are widely available at many institutions, allowing Raman spectroscopy to become a widespread analytical tool in mineralogy and other geological sciences. Hyperspectral imaging, ...

Improved detectors, new electro-optical devices and vastly improved computational power for data analysis have fueled the recent interest in combining biology and spectroscopy. This review article will cover three aspects of biomedical spectroscopy. (1 ) Data acquisition: what instruments are available for acquiring an image cube and what are the performance trade-offs involved in choosing one ...
