Description

Intelligent energy computer tomography system

Technical Field

The present invention relates to the field of medical devices, and more particularly, to a method and medium for a computed tomography system, an energy architecture and management thereof.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art, nor is it intended that such statements be considered as admissions of prior art that have been disclosed or known to the public at the time of filing.

General Computed Tomography (CT) system drives the tube to generate X-rays when scanning, and the output energy of the high voltage generator is usually divided into several levels, for example, 80kV, 100kV, 120kV or 140kV, and in some special cases, the highest voltage may be higher. In the working process, under the input of a common alternating current 380V voltage, the whole alternating current input current is also very large and basically reaches more than 100 amperes. The unit of use of the computed tomography system needs to configure a power line according to the maximum peak power of the computed tomography system and certain redundancy, and generally requires to be capable of transmitting power of more than 80 kVA.

Fig. 1 is a schematic diagram of energy supply Distribution of a conventional computed tomography system, in which a medical device outputs an ac voltage of about 380V, and a Power Distribution Unit (PDU) distributes Power of the medical device to components of a gantry, a scanning bed, a console, etc. of the computed tomography system to meet Power requirements of different components.

For a newly purchased computed tomography system, a medical equipment special line needs to be additionally arranged or the original line needs to be increased in capacity, the construction cost of the special line relates to pipeline installation and line laying, the cost is not trivial, and the cost is up to tens of thousands yuan in some cases.

In the process of completing the present invention, the inventor finds that for CT scanning, a reasonable CT scanning is about 3 minutes or more, but the time for actually operating at high power is only a few seconds, which is tens of seconds in extreme application, and the cumulative high power requirement per working day is about 1000 seconds. In order to support such high power scanning, a dedicated line of medical equipment must be provided, which is not practical.

The inventor finds that even if a special power line is configured, when the quality of external energy is unstable, the CT still cannot work normally, and the CT has a problem of high dependence on the external energy and the quality thereof.

The inventor finds in the process of completing the invention that the general whole body computed tomography system configured by the medical institution now basically configures a high voltage generator with peak power larger than 30kW inside. In use, the CT acts as an electrical load, and represents a large dynamic range of power demand. The difference between the maximum peak power and the standby power in the using process is often more than 30 kW. In the using process of the general whole-body CT used by medical institutions, the energy requirement is expressed in that the switching speed from the standby process to the peak value scanning is high, the rapid balance is needed, and the power, the internal resistance and the energy of the energy have the internal requirements of a single energy consumption component and the global performance requirement of the whole system.

The inventors have discovered in the course of completing the present invention that a general whole body CT used in medical institutions has an upper limit in its power requirement during use, which is determined by the maximum peak power requirement of the computed tomography system.

In the course of completing the present invention, the inventor finds that, in the actual use process of CT, due to the radiation dose safety, the medical ethical limitation, and the intrinsic property requirements of the core device, there is an upper limit on the exposure time of one scan and high-power radiation, and therefore, there is an upper limit on the required energy corresponding to one scan.

The inventor also finds that under the conditions of low equivalent internal resistance, low input power and unqualified voltage fluctuation of an external power grid, a user even needs to newly transform basic facilities such as a local area power grid transformer and the like, even equips special power generation equipment, and the cost is higher.

The modules are merely illustrative and different aspects of the systems and methods may use different modules.

Refer to fig. 2 to 5. The computed tomography system of some embodiments of the present invention includes a built-in energy subsystem and energy consuming components, the energy subsystem including an energy module and an energy bus.

Referring to fig. 2, the energy module may include at least one energy module, and the energy module may include energy modules (140, 142, 144, 146, 148, 150, 152, 154) in a distributed arrangement, each energy module corresponding to at least one energy consuming component (110, 112, 114, 116, 118, 120, 122, 124).

The energy consuming component may be any energy consuming component within the computed tomography imaging system, such as: the device comprises a high-voltage generator, a bulb tube component, a rotor motor, a PCB (printed Circuit Board), a DMS (digital distribution System) data acquisition board, a temperature control system, a display screen and a scanning bed or a console. The maximum peak power required for the high pressure generator and bulb system components exceeds 30 kW. The power required by a rotor motor often exceeds 3 kW. The scanning standby power consumption of other PCB boards, DMS data acquisition boards, temperature control systems, display screens, scanning beds, control consoles and the like is less, usually less than 2.2kW, and sometimes even less than 1.5 kW.

In some embodiments of the present invention, an energy module may correspond to a plurality of energy consuming components within an energy subsystem, for example, an energy module may supply power to a plurality of energy consuming components with lower power consumption. The energy consumption component can be powered by the energy module in a direct or indirect mode, for example, the energy consumption component can be powered directly by the energy module connected with the energy consumption component, and the indirect power supply mode can be that the energy module directly connected with the energy consumption component is powered by other energy modules and then the energy module directly connected with the energy consumption component is powered by the energy module.

The computed tomography imaging system of some embodiments of the present invention is a system with a large dynamic range of power requirements, i.e., the difference between the scan peak power and the scan standby power is greater than or equal to 30kW during a patient scan cycle. The energy-supplementing module is suitable for completing energy supplement in a patient scanning interval, and the energy module can only store energy supporting one-time scanning.

Fig. 5 is a computer tomography system of the present invention, wherein each energy module may be energized via an energy bus based on the description of fig. 2. An adapter (180, 182, 184, 186, 188, 190, 192, 194) is provided between the energy bus and the energy module, the adapter being configured to convert energy of the energy bus into energy suitable for receipt by the energy module.

The energy storage module can be provided with an energy supplementing interface, and the energy storage module supplements energy through the energy supplementing interface.

The grid network is a standard ac grid, which may be a 220V or 110V grid.

In order to solve the above problem, the present invention further provides an energy management method based on the computed tomography system, including: monitoring the state of the energy bus, and judging whether energy supplement is supported or not; if yes, waiting for an energy supplementing instruction, and if not, giving an alarm for prompting; acquiring the state of an energy module, and judging whether the energy module can support one-time scanning; if the energy module can support scanning, waiting for entering scanning, and if the energy module can support scanning, performing energy supplement until the energy module can support scanning once.

To solve the above problem, the present invention further provides a non-transitory computer readable storage medium having stored thereon computer program instructions, the computer program instructions being executed by a processor to perform the aforementioned method for energy management of a computed tomography system.
