Background

The exposure accumulated value information of the CT needs to be recorded, most CT equipment manufacturers often adopt a scheme of recording the exposure times in seconds by using a database, and the technical scheme has the problem of trust of hospitals and CT equipment manufacturers due to the fact that the modification is too simple. The other scheme is that a hardware storage chip is adopted to store second exposure information, and the hardware of the counter is replaced when the bulb is replaced, so that the second exposure information displayed by the counter is the current exposure time of the bulb, and the total exposure time of the machine can be inquired in a database. The prior art scheme has the condition that the bulb is replaced and the counter is bound, the bulb and the exposure counter need to be replaced simultaneously theoretically when replaced, otherwise, the accumulated exposure time of the current machine can only be displayed, and the service time of the current bulb is not the service time of the current bulb.

Detailed Description

An embodiment of a maintenance-friendly exposure integrated value processing method according to the present invention will be further described with reference to fig. 1 to 6.

In order to realize the compatibility of the storage address and the compatibility of the data processing, the data storage device adopts FRAM storage, the original definition of FRAM storage space is unchanged, and the newly added bulb adopts a uniform format, and the storage space of one embodiment of the invention is defined as follows:

# define Addr _ TUBE0_ RECTIME 0x 50// TUBE0 data storage Address

The # define Addr _ TUBE _ NUM _ FLAG 0xF 2// is stored in a mode of AAAAAA with the total number of 4BYTE, the AA is changed after writing, otherwise, the default// 0xAAAAAAA +1NUM +8TUBE0 serial number

# define Addr _ TUBE _ latest _ num 0xF 6// the currently most recently recorded serial number, power-on access, if not 0-20, then fetch the last accumulated value from TUBE0, otherwise fetch according to the last address,

# define Addr _ TUBE0_ SerialNUM 0xF 8// 0x 100-8// TUBE0 sequence number Address

#define Addr_TUBE1_SerialNUM 0x100

#define Addr_TUBE2_SerialNUM 0x100 + 30*1

#define Addr_TUBE3_SerialNUM 0x100 + 30*2

......

When processing according to the new protocol, reserving 20 TUBEs from the start address of TUBE1 followed by every offset of 30BYTE is 600BYTE, only TUBE0 has no sequence number but stores only accumulated values according to this logical encoding because of the ambiguity of the requirements.

Write flags are added according to the new protocol: the method is used for distinguishing whether the processing is carried out according to a new protocol or not, and the mark is read for distinguishing when the power is turned on next time.

When processing according to a new protocol, the addressing mode of each TUBE is 8BYTE serial number +17BYTE seconds + 1BYTE initialization times +4BYTE RESRVED, and the memory address of the default bulb serial number is planned to the position of TUBE1-8 in order to facilitate the retrieval of the prior default bulb. Macros are defined as follows:

# define Addr _ TUBE0_ SerialNUM 0x 100-8// starting memory:

then the whole storage structure after adding the sequence number of TUBE0 is: TUBE0 serial number + TUBE1 serial number + TUBE1 total second count + TUBE1 initialization count +4null + TUBE2 serial number + TUBE2 total second count + TUBE2 initialization count +4 null.
