WPF Image Zoom fixed to absolute window position and not relative mouseposition

public partial class MainWindow : Window
    {
        private double zoomScale = 1.0;

        public MainWindow()
        {
            InitializeComponent();
        }
       private void ZoomedImage_MouseWheel(object sender, MouseWheelEventArgs e)
        {
            // Get the mouse position relative to the image
            Point mousePos = e.GetPosition(imagemap);

            // Adjust the zoom scale based on the mouse wheel delta
            double delta = e.Delta > 0 ? 0.1 : -0.1;
            zoomScale += delta;

            // Constrain the zoom scale within reasonable limits
            zoomScale = Math.Max(1.0, Math.Min(zoomScale, 10.0));

            // Apply the zoom scale using a ScaleTransform
            ScaleTransform scaleTransform = new ScaleTransform(zoomScale, zoomScale);
            
            // Set the center of the ScaleTransform to the mouse position
            scaleTransform.CenterX = mousePos.X;
            scaleTransform.CenterY = mousePos.Y;

            imagemap.RenderTransform = scaleTransform;

            e.Handled = true; // Prevent scrolling
        }
    }
