Patient registration in a Radiology Information System (RIS) involves the process of collecting and recording patient information before their radiology examination or procedure. The RIS is a specialized software system used by radiology departments and imaging centers to manage and track patient-related data. The patient registration process in a RIS typically includes the following steps:

1 Patient Demographics: The registration process begins by collecting basic patient information such as name, address, date of birth, gender, contact details, and insurance information. This information is essential for identifying and communicating with the patient. 

2 Medical History: The RIS may also include sections for recording the patient's medical history, including past illnesses, surgeries, allergies, and any relevant pre-existing conditions. This information helps radiologists and technicians to understand the patient's health background and make informed decisions during the imaging procedure.

3 Referring Physician Details: The system may require inputting the name and contact information of the referring physician who ordered the radiology examination. This information is important for communication and coordination between the radiology department and the referring healthcare provider.
