Only current gallery images with get_attached_media

Found an answer using Shortcode which helped: How to get Page/Post Gallery attachment images in order they are set in backend using WP_Query()?

My working code now looks like this:

// Extract the shortcode arguments from the $page or $post
$shortcode_args = shortcode_parse_atts(get_match('/\[gallery\s(.*)\]/isU', $post->post_content));

// get the ids specified in the shortcode call
$ids = $shortcode_args["ids"];

$attachments = get_posts(
    array(
        'include' => $ids, 
        'post_status' => 'inherit', 
        'post_type' => 'attachment', 
        'post_mime_type' => 'image', 
        'order' => 'menu_order ID', 
        'orderby' => 'post__in', //required to order results based on order specified the "include" param
    )
);

if ($attachments) {
        foreach ( $attachments as $attachment ) {
    $urlArr[] = wp_get_attachment_url($attachment->ID);
    $titleArr[] = $attachment->post_title;
        }
    }
