CASSOLA, Vagner Ferreira  and  HOFF, Gabriela. Development of a software for evaluation and control of sensitometric characteristics in automatic films processing. Radiol Bras [online]. 2007, vol.40, n.2, pp.123-126. ISSN 0100-3984.

OBJECTIVE: To develop of a software tool for evaluation and control of sensitometric curves. MATERIALS AND METHODS: A method was developed for obtaining high- and low-contrast films sensitometric values, with no need to define wedge steps. RESULTS: The software named Sensito was implemented and tested utilizing data of sensitometric strips from conventional radiology, hemodynamics, and mammography departments. The feasibility of analyzing sensitometric curves from these areas remained evidenced with no need of user-dependent adjustments, and with no deviation in the evaluated sensitometric parameters and variations. CONCLUSION: The software allows the creation of a database including sensitometric curves from different processors in a same institution, easily generating gamma curves of a register and constant charts of the evaluated sensitometric characteristics, constituting an important tool for sensitometric control.

Keywords : Automatic processor; Sensitometric curve; Sensitometry.
