Smartphone adapter time trial analysis: A low-cost, time-efficient method to disseminate quality photomicrographs at the microscope.

Abstract

Within the field of pathology there is a need for a uniform low-cost option for securing high-quality photomicrographs. Advances in smartphone photography and 3D-printing technology allow for custom adapters to be designed for the purpose of photomicrograph capture. Photomicrograph acquisition was performed using four core modalities: a novel 3D-printed smartphone-to-microscope adapter, freehand smartphone-to-microscope technique, a commercial adaptor (LabCam Pro), and a microscope-mounted digital camera. Eight skin diagnoses were photographed using each of the modalities and time to image capture was measured. The photomicrographs were blindly reviewed by two academic dermatopathologists and one pathologist using a side-by-side comparison technique to determine the image quality. Cost assessments were evaluated by obtaining free pricing information on manufacturer websites. The 3D-printed adapter was the most efficient method of capturing a high-quality photomicrograph in addition to being budget neutral. The microscope-mounted camera produced the highest quality photomicrographs followed by the 3D-printed adapter. The 3D-printed smartphone-to-microscope adapter offers a low-cost, time-efficient method of capturing high-quality photomicrographs.
