FetalCal — Fetal Assessment Toolkit FetalCal is a clinical support application that processes user-entered fetal ultrasound measurements to calculate biometry parameters, Doppler indices, and MCA MoM values. It is designed to assist healthcare professionals in organizing, reviewing, and documenting fetal assessment data. The application supports calculation workflows by applying established formulas and reference data to user-provided inputs. Overview: FetalCal enables users to enter fetal measurements and Doppler values to generate calculated indices such as estimated fetal weight, centiles, z-scores, and ratios. It reduces the need for manual calculations and reference lookups. Functionality: Users enter fetal ultrasound measurements, including head circumference (HC), abdominal circumference (AC), femur length (FL), and Doppler values (UA, MCA, CPR, UtA, DV). The application processes these inputs to generate: • Estimated fetal weight, centiles, and z-scores. • Doppler indices, including umbilical artery, middle cerebral artery, uterine arteries, and related ratios. • MCA peak systolic velocity converted to MoM Results are presented in a structured format. All calculations are based on user-entered data; the application does not acquire or generate measurements independently. Modules: Biometry • Input: HC, AC, FL. • Output: estimated fetal weight (EFW), centiles, z-scores. • Visual categorization of results. Doppler • Input: Doppler measurements PI – UA, MCA, CPR, UtA, DV • Output: calculated indices and percentiles. MCA MoM • Input: MCA peak systolic velocity. • Output: MoM value with categorized interpretation. Output and Use • Structured summary of calculated values. • Supports documentation and reporting workflows. • Data can be saved and reviewed within the application. • Export options available for sharing or record-keeping. Key Characteristics • Operates without requiring an internet connection. • Single data entry workflow across modules. • Stores user-entered assessments locally and allows review of saved data. Intended Use This application is intended for use by healthcare professionals, including radiologists, sonographers, obstetric care providers, and maternal-fetal medicine specialists. Important Information: • This application is intended for clinical support and educational purposes only. • Clinical decisions should be made by qualified professionals using appropriate judgment and standard guidelines. • It should not be used as a sole basis for medical decision-making. • Users should rely on their clinical expertise and institutional protocols. • This application does not replace standard clinical workflows or institutional protocols. Monetization: There are no in-app purchases, subscriptions, or external payment mechanisms within the application. References Calculations are based on established medical literature and commonly used reference standards in fetal medicine.
