Can mobile DR be used to shoot the lumbar and cervical spine?

Some customers asked us if the mobile DR can be used to take lumbar spine and neck shots? I told my client that a larger amount of mobile DR is needed to shoot the lumbar spine. Is it more expensive for customers to ask such mobile DR? Reply to the customer Yes. The customer said that he has a 500ma high-frequency machine, which used a film processing system before. Can it be upgraded and changed to a digital system mobile DR, and then used to shoot the lumbar spine? It’s okay to reply to the customer, and only need to buy a digital system to become a mobile DR. Then, I sent the product information of the digital system of the flat panel detector to the customer to inform our engineers that they can come to upgrade. Customers said that they would study it first, and then determine the details of the upgrade later.
