摘要： A digital radiographic imaging system includes an offset table for determining mechanical and structural offsets which would, if not corrected, misalign the source and detector during use. The method can correct for inaccuracies in mechanical linkages, examination rooms and other mounting structures, and “drift” induced during use of the system.

摘要： A system and method for automatically positioning an image receptor based on the position of a manually positioned diagnostic source assembly in an X-ray imaging device is provided. In a preferred embodiment of the automated tracking system, an operator manually positions a diagnostic source assembly (DSA) over the area of a patient to be imaged. Sensors in the diagnostic source assembly transmit the position of the DSA to a system controller. The system controller then calculates an optimal position of an image receptor based on the position of the DSA. Once the optimal position is calculated, the system controller sends the optimal position to a motor drive, which positions the image receptor in the calculated optimal position. Position sensors in the image receptor then send positional data of the image receptor to the system controller, which verifies that the image receptor is in the calculated optimal position. If the operator wishes to manually adjust the image receptor, they may override the motor drive and do so. The automated tracking system provides for reduced total imaging time and increased cost effectiveness over prior X-ray imaging systems by reducing the number of retakes required to obtain a satisfactory X-ray image. Reducing retakes also results in decreased exposure to radiation by the patient being imaged which is healthier to the patient.

摘要： In one embodiment, a method for coordinating operation of X-ray detectors in a wireless X-ray system includes detecting multiple wireless X-ray detectors within an operative range of an X-ray base station, the detected X-ray detectors each having one of multiple possible statuses, including an active status corresponding to a designation of the X-ray detector as a desired recipient of radiation during a current X-ray imaging sequence, an inactive status corresponding to a designation of the X-ray detector as not the desired recipient of radiation during a current X-ray imaging sequence, and an unenabled status corresponding to the X-ray detector not being configured to operate with the X-ray base station.

摘要： An I/O system includes a Digital Device selecting a digital output to be set and a Digital I/O Expansion Mechanism, electrically coupled to the Digital Device. The Digital I/O Expansion Mechanism includes an input bank, a FIFO, and an I/O line. The Digital I/O Expansion Mechanism clears a stored value in the first input bank, samples the first value of the first input bank, and detects a change in the input bank. The Digital I/O Expansion Mechanism also stores a state of a data bit of the input bank along with a bank identifier in the FIFO. The Digital I/O Expansion Mechanism still further samples the I/O line via a first READ cycle and drives the I/O line with a next data entry from the FIFO. Digital I/O Expansion Mechanism samples all digital inputs and stores any detected changes in the FIFO. The Digital I/O Expansion Mechanism transmits all values in the FIFO to the Digital Device during a subsequent READ cycle and transmits to the Digital Device a last value read. The Digital I/O Expansion Mechanism also changes a digital output when a first WRITE command occurs and the Digital Device explicitly selects the digital output to be set and writes an entire bank in response to a bit change. Additionally, the Digital I/O Expansion Mechanism decodes and latches the digital output until the digital output is overwritten via a second WRITE command to the input bank from the Digital Device.
