Magento – How to list all parent categories

I'm trying to get all parent categories except root category from the collections returned using Mage::getModel('catalog/category');

My code :

$_category = Mage::getModel('catalog/category');    
    $_categories = $_category
                    ->getCollection()
                    ->addAttributeToSelect(array('name', 'image', 'description'));

    foreach ($_categories as $_category){
        print_r($_category);
        die(0);
        echo $_category->getName().'<>';

}

Output is :

Mage_Catalog_Model_Category Object (
    [_eventPrefix:protected] => catalog_category 
    [_eventObject:protected] => category 
    [_cacheTag:protected] => catalog_category 
    [_useFlatResource:protected] =>

        [level] => 0 
        [children_count] => 45 
        [name] => Root Catalog
    ) 
    [_hasDataChanges:protected] => 1 
    [_origData:protected] => Array (
        [entity_id] => 1 
        [entity_type_id] => 3 
        [attribute_set_id] => 0 
        [parent_id] => 0 
        [created_at] => 2013-09-14 12:39:35 
        [updated_at] => 2013-09-14 12:39:35 
        [path] => 1 
        [position] => 0 
        [level] => 0 
        [children_count] => 45

    ) 
    [_idFieldName:protected] => entity_id 
    [_isDeleted:protected] => 
    [_oldFieldsMap:protected] => Array () 
    [_syncFieldsMap:protected] => Array ()
)

May be I need to add an extra attribute for this? Any other idea please share
