"content": "The Dose Calibrator ecosystem links upstream component suppliers, midstream manufacturers and software firms, and downstream distributors to clinical end users. Upstream, suppliers deliver sealed radioactive sources, scintillation crystals and precision electronics that form the detector core. Midstream OEMs assemble these parts into calibrated instruments, embed dosimetry algorithms, and obtain regulatory certification. Downstream, channel partners distribute the devices to nuclear medicine departments, oncology clinics and research labs, where users verify administered activity for patient safety and compliance. Value is created by converting raw components into traceable measurement capability and captured through equipment sales and service contracts."
