A method for determining a subject's orientation includes receiving, at an imaging system, an input that indicates an orientation of a subject being imaged, automatically determining the orientation of the subject using a feature recognition system, comparing the received input to the automatically determined orientation, and generating an image, the image including orientation indicia based on the comparison. An object orientation recognition system and an imaging system are also described herein.

A method and apparatus are provided for minimizing output pulse jitters in a phase locked loop. The method includes pre-setting the digital phase locked loop to a desired frequency, locking the digital phase locked loop to the desired frequency to generate an output signal, and filtering the output signal of the digital phase locked loop to maintain undesirable jitter to an acceptable range. In one embodiment, the apparatus is a medical imaging device. In another embodiment, the apparatus is a baggage imaging device.

Systems and methods for using a patient display is described. The described system includes a medical imaging system. The medical imaging system includes a gantry, a patient display, and a computer. The gantry at least partially circumscribes a patient viewing area. The patient display is viewable from the patient viewing area. The patient display is communicatively coupled to the computer. The computer is programmed to receive scan protocol instructions and control the patient display according to the predetermined scan protocol. It is further programmed to prompt the patient, using the patient display, to perform a bodily action that facilitates the scan and to provide the patient with at least one of entertainment and distraction using the patient display.

A computerized tomography (CT) system having an apparatus and method for receiving high data rate communication is disclosed herein. The apparatus includes a controlled variable attenuator for attenuating an encoded digital data signal having a wide range of power levels, a digital envelope detector for de-encoding the encoded digital data signal, a noise filtering circuit for filtering out the residual undesirable encoded signal components, and a feedback loop for maintaining a desired signal level such that the encoded digital data signal is converted to its pre-encoded state suitable for processing to generate a CT image.

RF slipring receiver for a computerized tomography system

The present invention, in one form, is a communication system for transmitting high-speed data across an imaging system slip-ring. In one embodiment, the communication system includes a transmitter and a receiver. The transmitter generates encoded serial data that is transmitted across the slip-ring 1 bit at a time to the receiver. The encoded data includes command codes, message blocks having CRC data, and SYNC data. Using the commands codes, the receiver decodes the data into byte data. The receiver utilizes the CRC data to detect and correct errors in the transmitted data and the SYNC data to synchronize the receiver with the transmitter.

Methods and apparatus for exchanging data in an imaging system

A serial digital bit signal having signal bits occurring in a bit interval and at a signal bit speed, and each signal bit representing, alternatively, a first logic state and a second logic state, is transferred across a rotating interface by encoding each first logic state bit with a digital radio frequency (RF) carrier signal and coupling the encoded signal across the interface with an RF slipring.

Digital encoding of RF computerized tomography data

Dual control of image level and window of a display is accomplished by rotation of a single trackball. Rotation of the trackball within a first band including the X axis controls one parameter, and rotation of the trackball in a second band including the Y axis controls a second parameter. No changes are made in the parameters in response to rotation of the trackball in a third deadband laying between the first band and second band. The operator of a tomography system can readily change display parameters by rotation of the trackball while viewing the display.
