Information display device and control device of medical equipment
An information display device and a control device of medical equipment are provided. The information display device of medical equipment includes at least one projection unit for acquiring display information, and projecting the display information onto a housing of the medical equipment. The information display device includes a host for providing an electrical signal of the display information, an optical fiber converter for converting the electrical signal to an optical signal, and an optical fiber for relaying the optical signal to the projection unit. Various display information about medical equipment is not displayed through an electronic display screen, but the display information is projected onto the housing of the medical equipment by an additional projection unit.
1. A control device of magnetic resonance equipment, the control device comprising:
an information display device of the magnetic resonance equipment, the information display device comprising:
a projector configured to acquire display information and project the display information onto a surface of a housing of the magnetic resonance equipment, the housing defining a bore hole of the magnetic resonance equipment;
a host operable to provide an electrical signal of the display information;
an optical fiber converter operable to convert the electrical signal into an optical signal; and
an optical fiber operable to relay the optical signal to the projection unit;
a light capture device configured to capture light change information about a display image projected onto the housing of the magnetic resonance equipment;
a position encoder operable to determine a control instruction based on the light change information, wherein the position encoder comprises an optical position encoder;
a controller configured to control the magnetic resonance equipment based on the control instruction; and
a photoelectric converter arranged between the position encoder and the controller, the photoelectric converter configured to convert a light control instruction determined by the optical position encoder to an electrical control instruction,
wherein the controller is configured to control the magnetic resonance equipment based on the electrical control instruction.
2. The control device of claim 1 , wherein the controller is further configured to:
control a sickbed in response to the electrical control instruction;
control sound in response to the electrical control instruction;
control a fan in response to the electrical control instruction; and
control an air conditioner in response to the electrical control instruction.
3. The control device of claim 1 , wherein the information display device further comprises a fixation unit operable to fix the projector.
4. The control device of claim 3 , wherein the fixation unit is arranged on a surface separate from the magnetic resonance equipment.
5. The control device of claim 4 , wherein the surface separate from the magnetic resonance equipment comprises a roof, a wall, or the roof and the wall of an area for accomodating the magnetic resonance equipment.
6. The control device of claim 3 , wherein an arrangement position of the fixation unit is fixed or adjustable.
7. The control device of claim 1 , wherein a projection range of the projector comprises an upper portion of a front opening of a rack of the magnetic resonance imaging system, a left portion of the front opening of the rack of the magnetic resonance imaging system, a right portion of the front opening of the rack of the magnetic resonance imaging system, an upper portion of a rear opening of the rack of the magnetic resonance imaging system, a left portion of the rear opening of the rack of the magnetic resonance imaging system, a right portion of the rear opening of the rack of the magnetic resonance imaging system, or any combination thereof.
8. The control device of claim 1 , further comprising:
a splitter operable to:
split the display information as multiple channels of sub-display information; and
send each channel of the sub-display information to a corresponding projector.
9. The control device of claim 1 , wherein the projector is also configured to project the display information onto a surface separate from the magnetic resonance equipment.
10. The control device of claim 9 , wherein the surface separate from the magnetic resonance equipment comprises a wall of an area for accomodating the magnetic resonance equipment.
