4D Mammography

About Calidar

Calidar is a private, pre-revenue biotech company developing a novel diagnostic imaging platform called 4D Mammography. The technology utilizes X-ray diffraction to capture molecular-level signatures or 'tissue fingerprints' associated with cancer, aiming to improve the precision of breast cancer screening and diagnosis without the need for biopsy or contrast agents. The company achieved a first-in-human milestone in August 2025, initiating a pilot study for its lead program. Calidar's value proposition centers on providing a fast, lower-dose, and noninvasive tool that could potentially reduce false positives and enable earlier intervention in breast cancer care.
