Portable automatic control system for capsule endoscopy in stomach

An automated endoscopy machine comprising:

• a stationary platform that a person stands on for testing;
• a rotating ring that rotates around person standing on the stationary platform, wherein an axis of rotation of the rotating ring passes through a head and a stomach of the person;
• a first electromagnet mounted to a first actuator that adjusts a height of the first electromagnet, the first actuator mounted to the rotating ring by a first supporter;
• a second electromagnet mounted to a second actuator that adjusts a height of the second electromagnet, the second actuator mounted to the rotating ring by a second supporter;
• a capsule in the stomach of the person during testing, the capsule having a battery, wireless transceiver, a primary magnet along a longitudinal axis of the capsule, a camera, and a light source for the camera;
• a wireless transceiver for receiving images of the stomach that are captured by the camera in the capsule;
• a processor;
• a first magnet current driver for generating a first current to the first electromagnet to cause the first electromagnet to generate a magnetic field that creates a movement force on the primary magnet inside the capsule;
• a second magnet current driver for generating a second current to the second electromagnet to cause the second electromagnet to generate a magnetic field that creates a movement force on the primary magnet inside the capsule;
• a control program executing on the processor, the control program moving the capsule along a movement line between the first electromagnet and the second electromagnet by commanding the first magnet current driver to increase the first current and by commanding the second magnet current driver to maintain or decrease the second current;
• wherein the movement line is a line that passes through the first electromagnet and passes through the second electromagnet;
• a rotation motor that rotates the rotating ring in response to a rotation command from the control program executing on the processor, wherein the movement line is rotated, allowing the capsule to rotate within the stomach;
• wherein the control program moves the capsule vertically by commanding the first actuator to adjust the height of the first electromagnet, and by commanding the second actuator to adjust the height of the second electromagnet;
• and
• a plurality of movement commands issued by the control program that causes the capsule to move along a path within the stomach, wherein the control program commands the capsule to activate the camera to capture images at points along the path;
• whereby the person is screened to capture stomach images automatically by execution of the control program, wherein the control program moves the capsule along the path and for automated image capture along the path.

A standing endoscopy screening machine comprising:

• a stationary place that a person stands on for endoscopy screening;
• a rotating ring that rotates around a Z axis that passes thought a head and a portion of a stomach of the person standing on the stationary place;
• a motor for rotating the rotating ring around the Z axis;
• a first supporter attached to the rotating ring, the first supporter supporting a first electromagnet assembly having a first electromagnet that is movable in a Z direction by a first actuator, the Z direction being orthogonal to a plane of the rotating ring;
• a second supporter attached to the rotating ring, the second supporter supporting a second electromagnet assembly having a second electromagnet that is movable in the Z direction by a second actuator;
• a wireless transceiver;
• a capsule that is swallowed by the person and enters a stomach of the person, the capsule having a battery, a camera that captures images of the stomach, a wireless transmitter that transmits the images to the wireless transceiver, and a primary magnet;
• a processor executing a control program, the control program causing the capsule to
• move vertically in the Z direction by commanding the first actuator to move the first electromagnet up or down while sending a first current to energize the first electromagnet, and by commanding the second actuator to move the second electromagnet up or down while sending a second current to energize the second electromagnet,
• move horizontally in an X direction that is orthogonal to the Z axis by sending the first current to energize the first electromagnet and sending the second current to energize the second electromagnet, wherein the first current has a higher magnitude over time than and the second current, causing the first electromagnet to exert a greater force on the capsule than a force exerted by the second electromagnet when horizontal movement is performed;
• and
• rotate around the Z axis, the control program sending a command to the motor to rotate the rotating ring by a radial angle;
• wherein the control program sends a commands to the motor, actuators, and electromagnets to perform movements of the capsule to trace a path through the stomach, wherein the control program receives images from the capsule as the capsule moves along the path through the stomach,
• whereby images of the stomach are automatically captured by the capsule as it is moved along the path by the control program controlling the motor, first electromagnet, second electromagnet, first actuator, and second actuator.
