Apparatus and methods for a projection display device on X-ray imaging devices
Apparatuses and methods are provided for projecting a display of information for an x-ray device. The display of information is projected on the patient, on the table 205 area or on a combination thereof. A compact projector 207 is provided to project the display of information on a previously unused region of the patient and table 207 , and provides a source of diagnostic and safety information without further crowding the room. The projected display of information may be a system state, a patient state, a surgical tool position or another relevant image. A compact sensor or range scanner 209 may be employed to capture three-dimensional distance information in the x-ray system. The three-dimensional distance information may be used to reduce distortion in the projected image, selectively darken regions of the projected image, automatically configure the x-ray system, capture inputs from the operator and improve safety in the x-ray system.
1. An x-ray system comprising:
an x-ray emitter;
an x-ray detector;
a table configured to receiving an object to be irradiated;
an operator interface comprising:
an projector configured to project a display of information on the table, on the object, or on the table and the object; and
a sensor configured to capture an image with distance measurements,
wherein the distance measurements are distances from the sensor.
2. The x-ray system of claim 1 , wherein the projected display of information comprises an x-ray system state, a patient state, a surgical tool position, or a marketing image.
3. The x-ray system of claim 1 , wherein the projected display of information comprises a fluoroscopy image or a sequence of saved images projected directly on the object.
4. The x-ray system of claim 1 , further comprising:
a radio-transparent surface placed over the object.
5. The x-ray system of claim 4 , wherein the radio-transparent surface comprises a cloth.
6. The x-ray system of claim 1 , wherein the x-ray emitter or the projector are configurable using the distance measurements.
7. The x-ray system of claim 1 , wherein the projector is configured to project the display of information comprising an operator input gesture and location based on the distance measurements.
8. A C-arm x-ray system comprising:
a C-arm having a first end and a second end;
an x-ray source mounted to the first end;
an x-ray detector mounted to the second end;
a table configured for receiving a patient to be irradiated;
an operator interface comprising:
a projector configured to project a display of information on the table, on the patient, or on the table and the patient; and
a sensor configured to capture an image with distance measurements,
wherein the distance measurements are distances from the sensor.
9. The C-arm x-ray system of claim 8 , wherein the projector is mounted to the C-arm.
10. The C-arm x-ray system of claim 8 , wherein the projector is mounted to a fixed location above the table.
11. The C-arm x-ray system of claim 8 , wherein the projector is mounted to the C-arm; and further comprising:
an additional projector mounted to a fixed location above the table.
12. The C-arm x-ray system of claim 11 , wherein the projector mounted to the C-arm is configured to project the display of information and the additional projector is configured to project a second display of information.
13. A method for a projection display on an x-ray imaging device, the method comprising:
orienting an x-ray source and an x-ray detector relative to a table;
projecting, by a projector, an operator interface including a display of information on the table, on an object to be irradiated on the table, or on the table and the object; and
obtaining an image with a sensor,
wherein the image comprises distance measurements that are distances from the sensor, and
wherein the projected operator interface comprises an x-ray device state of the x-ray imaging device, a patient state, a surgical tool position, an x-ray image captured by the x-ray detector, or a marketing image.
14. The method of claim 13 , further comprising:
adjusting the operator interface based on the distance measurements.
15. The method of claim 14 , wherein adjusting the operator interface comprises reducing a distortion by adjusting a projected image shape or a focus of the projected operator interface.
