Infantile Hemangiomas Evaluation and Monitoring Using a Wireless DOS Device

The goal of the Wireless Imager Project is to design, develop, and validate a handheld wireless device (HWD) to perform near-infrared spectroscopic measurements on infantile hemangiomas (IH). This device contains four sources and two photodetectors distanced 0.6 and 2.0 cm apart. Raw data, as recorded by the detectors, is used to evaluate hemoglobin concentrations and tissue oxygen saturation of superficial tissue. An accompanying software package was developed for an Android based mobile phone which can be used to directly control the imaging device. This makes the imaging system easy to use in a clinical setting. The device is currently in the validation phase as it is being used in a pilot longitudinal study at the School of Medicine at Columbia University.
