A portable system to be inserted within the birth canal for measuring dilation of a cervical region is disclosed. The system comprises a housing having a first portion sized to conform to a user's hand thereby defining a handle and a second portion sized to be inserted into the birth canal. The system includes two structured light sources configured to project a pattern onto the cervical region, a sensor, a trigger interface, a power source, and the processor configured for capturing image sensor data. The processor is configured for receiving image data from the sensor, processing the image sensor data, calculating a measurement of the dilation of the cervical region, and transmitting the data. The processor will transmit the data onto the display, presenting the measurement of dilation as well as a visual representation of the measurement.
