Positioning system of mobile X-ray machine

Abstract

A positioning system for a mobile X-ray machine includes multiple radio frequency (RF) transmitters respectively installed on multiple mobile X-ray machines, multiple RF receivers respectively installed at multiple different locations, and a processing device. Each RF transmitter is used to transmit an RF signal, and each RF receiver is used to receive the RF signal transmitted by the RF receiver and generate RF intensity information based on the RF signal. The processing device is connected to the multiple RF receivers to receive the RF intensity information respectively and determine the position of each mobile X-ray machine based on the RF intensity information transmitted by the multiple RF receivers. The user (radiologist) can thus know the movement of each mobile X-ray machine in real time, reduce the waiting time of the examinee and improve the examination efficiency.

Claims

1. A positioning system for a mobile X-ray machine, comprising: a plurality of radio frequency (RF) transmitters respectively disposed on a plurality of mobile X-ray machines, each RF transmitter transmitting an RF signal; a plurality of RF receivers respectively disposed at a plurality of different locations, each RF receiver receiving the RF signal transmitted by the RF transmitter and generating RF intensity information based on the RF signal; and a processing device connected to the plurality of RF receivers to receive the RF intensity information respectively, the processing device determining the position of each mobile X-ray machine based on the RF intensity information transmitted by the plurality of RF receivers; when the processing device determines that one of the plurality of mobile X-ray machines is located at one of the plurality of locations, the processing device counts a dwell time; the processing device presets a dwell time threshold, when the processing device determines that the dwell time is greater than or equal to the dwell time threshold and the mobile X-ray machine remains at the position, the processing device counts an idle time; the processing device calculates an idle rate of each mobile X-ray machine based on the idle time of each mobile X-ray machine in a set time period.

2. The positioning system for the mobile X-ray machine as described in claim 1, wherein: Each of the radio frequency transmitters is a Bluetooth transmitter, and each of the radio frequency receivers is a Bluetooth receiver.

3. The positioning system for the mobile X-ray machine as described in claim 1, wherein: Each of the radio frequency transmitters is an ultra-wideband transmitter, and each of the radio frequency receivers is an ultra-wideband receiver.

4. The positioning system for the mobile X-ray machine as described in claim 1, wherein: The processing device calculates a movement time for each mobile X-ray machine to move between the plurality of locations based on the time point at which the radio frequency intensity information is received from the plurality of radio frequency receivers.

5. The positioning system for the mobile X-ray machine as claimed in claim 1, further comprising: a display device connected to the processing device and used to display the positions of the plurality of mobile X-ray machines.

6. The positioning system for the mobile X-ray machine as described in claim 1, wherein: These multiple RF receivers support Power over Ethernet (PoE).
