Abstract

The invention proposes a system that provides a simplified technique to integrate a mobile C-arm X ray system with a mobile patient positioner to assist in repeatability and reproducibility of performing acquisition of X-ray or fluoroscopic images/sequences of a specific anatomical region of body of a patient, such as, the heart from specific viewing directions that help visualize region of interest. The invention further includes a technique for arranging the mobile C-arm X-ray imaging system and the mobile patient positioner in a constrained radial orientation with respect to a common vertical axis. The technique, thereby, provides a common reference polar coordinate system for repeatable, reproducible articulation of the mobile C-arm system and the mobile patient positioner during an interventional or surgical procedure.

MOBILE C-ARM X-RAY IMAGING SYSTEM

FIELD OF INVENTION

The present invention generally relates to X-ray imaging system and more particularly to a technique to integrate a mobile C-arm X ray system with a mobile patient positioner.

BACKGROUND OF THE INVENTION

Generally, fixed room interventional X-ray systems have both the C-arm X-ray gantry and the patient positioner permanently installed into the procedure room. They are also wired together to exchange power, control signals and data in order to operate in an intelligent coordinated fashion. 

These systems enable users to reproduce specific orientations of the C-arm and the patient positioner in order to acquire images/sequences of a specific anatomical region of body of a patient from specific viewing directions that best visualize region of interest with considerable ease (automation), repeatability and reproducibility.  However, such fixed room interventional X-ray systems are expensive and are often beyond affordability of hundreds of medical practitioner in many emerging countries.

As a cost effective alternative to the fixed room interventional X-ray system, mobile C-arm X-ray systems have been adopted for interventional procedures in some emerging countries. In such situations, customers rely on third party mobile patient positioners that are only partially integrated into complete solution to enable procedures. However, mobile C-arm X-ray systems do not provide convenient or efficient workflow as that of fixed room interventional X-ray systems. 

The lack of complete integration, poor intelligence gathering / sharing and lack of sufficient automation in the operation of a mobile C-arm X-ray system with a mobile patient positioner results in increased procedure time, increased stress and discomfort to patients and caregivers and possibly increased duration of X-ray radiation/dosage to the patient and caregivers. 

The absence of any mechanical integration in the present use of mobile C-arm X-ray systems and mobile patient positioner makes it even more challenging to leverage any existing electronics both within the C-arm X-ray system and the patient positioner.  Therefore placing mobile C-arm X-ray system and patient positioner physically in a common co-ordinate system with the help of a mechanical coupling / hinge joint opens many opportunities to add desired intelligence and automation into the whole system for obvious user and patient benefits.

Therefore there exists a need for enabling a simple cost effective and better way of integrating a mobile patient positioner with a mobile C-arm X-ray imaging system in mechanical and electronic aspects.

BRIEF DESCRIPTION OF THE INVENTION

The invention proposes a system for X-ray/fluoroscopic images/sequences acquisition of a patient during interventional/surgical procedures that includes a mobile C-arm X-ray system, a mobile patient positioner and a vertical axis pivot, wherein the pivot engages the C-arm and the patient positioner togethe...
