            idArray.push(this.id);
            console.log(this.id)
        });
    });
</script>

Use event target for this:

$("#Map").on("click", function(e){
    alert(e.target.id);
})


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

         <td><img src="~/Images/Dental.jpg" width="663" height="474" border="0" usemap="#Map" /></td>
    </tr>
</table>

You can use this as your javascript. 

$(document).ready(function () {
    var idArray = [];
    $('#Map>area').on('click',function () {
        idArray.push(this.id);
        console.log(this.id)
    });
});

To get all ids of <area> elements you can use $.map() to return id of current element of iteration. Use .on() click event to get the id of the clicked <area> element

let ids = $.map($("#Map area"), function(el) { return el.id });

console.log("all `id`s:", ids);

setTimeout(function() {
  console.clear();
}, 2000);

$("#Map area").on("click", function() {
  console.log(this.id)
})
