“…Studies conducted in developed country settings have investigated the use of cell phones on the patient end to generate feedback for improved chronic illness care and monitoring [7-9], increased medication compliance [10] and smoking cessation [11], or reduced missed clinic visits [12,13]. Additionally, other studies have investigated the use of cell phones on the provider end to transmit images for documentation [14] or diagnostic purposes [15-18]. However, few studies have investigated the use of mobile phones as a data collection tool in low income countries.…”

BackgroundTo investigate the feasibility, the ease of implementation, and the extent to which community health workers with little experience of data collection could be trained and successfully supervised to collect data using mobile phones in a large baseline surveyMethodsA web-based system was developed to allow electronic surveys or questionnaires to be designed on a word processor, sent to, and conducted on standard entry level mobile phones.ResultsThe web-based interface permitted comprehensive daily real-time supervision of CHW performance, with no data loss. The system permitted the early detection of data fabrication in combination with real-time quality control and data collector supervision.ConclusionsThe benefits of mobile technology, combined with the improvement that mobile phones offer over PDA's in terms of data loss and uploading difficulties, make mobile phones a feasible method of data collection that needs to be further explored.

“…Mobile devices, such as phones and tablet computers, have started to play an increasingly important role in clinic and research. In clinic, new ways are steadily introduced to record medical images, process them, and to enable quantification for diagnostic purposes (Yamada, Watarai, Andou, & Sakai, 2003;Razdan, Johannes, Kuo, & Bagley, 2006;Mudanyali et al, 2012;Rothman, Gupta, & McEvoy, 2017;Boissin, Blom, Wallis, & Laflamme, 2017). In research, advances in mobile imaging assist in microscopic imaging and spectroscopy (Smith et al, 2011;Skandarajah, Reber, Switz, & Fletcher, 2014;Kazemzadeh et al, 2015;Rojas, Fuentes, & Galvez, 2016;Scherr, Gupta, Wright, & Haselton, 2016).…”

Understanding the nature of fluorescently-labelled molecules requires proper quantification of their colocalization. We developed a new approach to enable quantification of colocalization of markers in fluorescence microscopy images using mobile computers. It consists of three interacting components: desktop computer - cloud - mobile device. After an image is opened on a desktop computer, it is then saved to the cloud and becomes available to a mobile device. Functionality of the desktop and mobile software consists of the same steps and therefore allows using any of the platforms when performing analysis. Changes of the state of the image between devices are synchronized via the cloud, so that nothing is lost when switching them. All interactions are performed seamlessly in the background and do not require any input from the researchers' side. This approach augments access to analytical imaging by allowing to work in completely new ways with superior levels of control, simplicity, and convenience. © 2018 by John Wiley & Sons, Inc.

“…For example, doctors have demonstrated new ways to interact with and record medical image data in specialties such as dermatology and neurosurgery [1]–[3]. To address healthcare needs in low-resource regions, researchers have also shown that mobile phones can bring traditional diagnostic assays to inadequately served populations [4]–[6].…”

“…Initial efforts to use mobile phone cameras for both medical and scientific applications highlighted these concerns, with some studies concluding that mobile phones are inadequate for pathology [1] or limited in their image quality [19]. However, other work has shown that a full-size microscope equipped with a phone camera can qualitatively capture relevant features of malaria and TB [6].…”

Quantitative Imaging with a Mobile Phone Microscope

Use of optical imaging for medical and scientific applications requires accurate quantification of features such as object size, color, and brightness. High pixel density cameras available on modern mobile phones have made photography simple and convenient for consumer applications; however, the camera hardware and software that enables this simplicity can present a barrier to accurate quantification of image data. This issue is exacerbated by automated settings, proprietary image processing algorithms, rapid phone evolution, and the diversity of manufacturers. If mobile phone cameras are to live up to their potential to increase access to healthcare in low-resource settings, limitations of mobile phone–based imaging must be fully understood and addressed with procedures that minimize their effects on image quantification. Here we focus on microscopic optical imaging using a custom mobile phone microscope that is compatible with phones from multiple manufacturers. We demonstrate that quantitative microscopy with micron-scale spatial resolution can be carried out with multiple phones and that image linearity, distortion, and color can be corrected as needed. Using all versions of the iPhone and a selection of Android phones released between 2007 and 2012, we show that phones with greater than 5 MP are capable of nearly diffraction-limited resolution over a broad range of magnifications, including those relevant for single cell imaging. We find that automatic focus, exposure, and color gain standard on mobile phones can degrade image resolution and reduce accuracy of color capture if uncorrected, and we devise procedures to avoid these barriers to quantitative imaging. By accommodating the differences between mobile phone cameras and the scientific cameras, mobile phone microscopes can be reliably used to increase access to quantitative imaging for a variety of medical and scientific applications.
