The pocket echocardiograph: a useful new tool?

AIMS Hand-carried ultrasound scanners are getting smaller. The Acuson P10 is the latest and smallest portable echocardiograph available on the market. METHODS AND RESULTS We tested the ability of this scanner to allow qualitative assessment of LV size and function in an unselected group of 30 patients [19 male, 11 female; mean age (SD) 64.7 (10.3) years] seen by a consultant cardiologist (acc...

Open-Source Colorimeter

The high cost of what have historically been sophisticated research-related sensors and tools has limited their adoption to a relatively small group of well-funded researchers. This paper provides a methodology for applying an open-source approach to design and development of a colorimeter. A 3-D printable, open-source colorimeter utilizing only open-source hardware and software solutions and r...

Application of a colorimeter for turbidity measurement

Development of Filters for a Thermoelectric Colorimeter

Filters have been designed for use with phoLocells and pho totubes in t ris Limulus colorimeters, but because of the variation in spectral response of t hese detecLors from one Lo t he other, it has not been worthwhile to attempt to achieve the best possible dup li cation or the CIE t ristim ulus func t ions. In t he case of a thermoelectric detector, however, th e response is so nonselective t...
