Outcome  TimePoints 
The significance of this research lies in its potential to improve the efficacy and safety of coronary computed tomography angiography (CCTA) By reducing radiation exposure and contrast agent use.

With a comparative analysis of different reconstruction techniques. This research aims to find the optimal reconstruction method to achieve high image quality in a low-dose protocol. This provides important insights for improving CT coronary angio.

Brief Summary
Modification(s)  

·       After all the approvals sample size screening will be executed with respect to    inclusion and exclusion criteria.

·       All the procedure will be explained to the patient and breath bold instructions should be given and heart rate should be monitored.

·       All the demographic details will be collected.

·       Scan will perform using the standard operating protocol

·       The best cardiac phase with least motion artifact will be reconstructed with respect to  R-R interval.

·       The best Phase will be selected and reconstructed using filtered back and iterative (idose  level 3) reconstruction algorithm  by keeping the filter CB constant

·       All the images will be then transferred to ISP server for image analysis.

·       Image will be analysed qualitatively and quantitively. For quantitative analysis ROI will be placed LM, RCA, LAD, LCX and Major branch to calculate CNR, SNR and image noise.

·       For qualitative analysis images will be accessed by two Radiologist without revealing the reconstruction technique to access image quality.
