A really wide range in which you can find any instrument synthesised and ready to be edited, if you want. The application has about six thousand loops, sound effects and music backgrounds that can be used in any recording. The program includes the simulation of certain music instruments, such as classic keyboards and samples of the main instruments of an orchestra.Ī huge collection of loops and sound effects. Mixcraft allows the user to carry out multitrack sound mixes, edit loops, add effects and edit audio, among many other functions, in order to create recordings and refined compositions with a great sound quality. When simplicity and professionalism go hand in hand However, a higher HR still increases stairstep and motion artefacts.Simplicity and quality often go in opposite directions, but that isn't the case of Mixcraft, a powerful program developed by Acoustica for audio production, mixing and recording, the easy handling of which doesn't hinder the professional results obtained. Unlike CCTA using narrow CT detectors, HRV has no significant effect on motion and stairstep artefacts using a wide CT detector with high z-coverage. No significant differences in image noise, CNR, SNR, and radiation dose were seen.

There was no significant effect of HRV on stairstep artefacts (r = 0.15, p = 0.416) and motion artefacts (r = 0.13, p = 0.311). Group 2 showed significantly increased step artefacts with a mean misalignment of 1.4 mm compared to 0.4 mm in Group 1 (p < 0.001). A significant correlation between HR and stairstep artefacts (r = 0.46, p < 0.001) and motion artefacts (r = 0.63, p < 0.001) was found. Image noise, contrast-to-noise-ratio (CNR), signal-to-noise-ratio (SNR), and radiation dose were assessed.

Stairstep artefacts were defined by measurements of misalignment. Motion artefacts were quantified using a 5-point-scale.

Patients were divided into two groups (Group 1: HR <65 bpm, Group 2 ≥65bpm). To evaluate the effect of heart rate variability (HRV) and heart rate (HR) on intra-image "motion" and inter-image "stairstep" artefacts in step-and-shoot coronary CT angiography (CCTA) using a wide detector CT scanner.Ħ6 patients underwent step-and-shoot CCTA using 256-slice CT.
