Clinical Study for Taichi Precise Image (Taichi)

August 11, 2026 updated by: Philips Clinical & Medical Affairs Global
The objective of the study is to evaluate the Image Quality (IQ), and diagnostic acceptability of Precise Image (PI) as compared with iDose4 as a standard-of-care reference. The study is designed to assess the performance of Precise Image algorithm on data collected from subjects scanned by CT Rembra RT, CT Areta RT or CT Rembra. This approach allows for the evaluation of image quality and diagnostic acceptability by comparing the PI algorithm with iDose4, which serves as the standard-of-care reference.
