Series numbering

About this task

Series numbering in the Patient List depends on the type of imaging application performed. Click an application below for more details or for a quick description of the application series numbering scheme, refer to the table below.

Table 1. Series numbering

Application

Created series number

Notes

3DASL

PW and PD phases are in same series

3DCINE-SPGR 3DCINE-FIESTA

Nx100

Two series are created: a preview series and a fully reconstructed anatomy cine series.

The series number of the preview series is multiplied by 100 for the full anatomy series.

Figure 1. 3DCINE example where series 15 and 16 are the preview 3DCINE series and series 1500 and 1600 represent the fully reconstructed anatomy series

4DFLOW

N×100*: the anatomy cine series,

N×100+1*: the LR flow cine series

N ×100+2*: the AP flow cine series

N ×100+3*: the SI flow cine series

The 4DFLOW series numbering is the number of the preview series multiplied by 100 for the fully reconstructed anatomy series and multiplied by 100 plus 1, 2 and 3 for the Left-Right, Anterior-Posterior and Superior-Inferior flow series, respectively.

For image pasting N is the lowest numbered series in the input data set.

N*100

N < 100

N >/= 100

DTI

N*100, N*100+1, N*100+2

Each group (CMB, T2, direction 1, direction 2,...) has all slices in the order of slice location.

T2 and all diffusion images are in a single series.

Given the order of groups and slices, the image number will start from 1 and end as (number of groups * slice number) with increment of 1. The following cell illustrates the series structure with multiple b-values. If Smart NEX is applied, the T2 group is not in the series.

Synthetic DWI

N*100

The Synthetic DWI series number is the original series # x 100.

Figure 3. Patient List with DWI source prospective series selected

DynaPlan

N*100 + p

N*100 + K + p

N = original (base) series number, p=phase number

COL + PJN in separate series, where K= total #phases, p=phase number

GSPS

N+100,000

Add 100,000 to source series when creating GSPS objects

FLEX

IDEAL

DISCO

100*N

100*N+1

100*N+2

(N*100)+99

N*100-1+i+k*nphase

N= original (base) series number which will always contain the Water images.

100*N: FAT

100*N+1: In-Phase

100*N+2: Out-of-Phase

100*N+99 only applies to IDEAL and not to Flex. The series is the 3 echoes of IDEAL that are collected during acquisition.

IDEAL, unlike Flex, synthesizes in-phase and out-of-phase echoes since it does not collect these. Flex in-phase and out-of-phase images are true source images that are collected.

When multi-phase (dynaplan) is selected along with the separate series per phase option, the *100 series numbering changes as follows:

Where i=phase number, k=0.3 (water, Fat, in-phase, out-phase, field map), note that the first water phase image is in series N which accounts for the –1. Again, there will be one block of numbers per image type with no place holders. Thus for N=4, 3 phases (0..2) W+F (0..1) the resulting series are: W(4 400 401) F(402, 403,404)

MAGiC

N*100+i

N : original (base) MAGiC series number that contains MDME images.

i : increasing number begins with 0 for all saved MAGiC images no matter if they are contrast weighted image series, Qmaps series, color qmap, screenshot.

Series number for the first saved series is the series number of the input images multiplied by 100, if the result is less than 10000, otherwise it is 100.
Series number is increased by 1 for each saved series.
If the series number is already used in the study, the system keeps increasing the series number until an available number is found.

Save Original

40,000+N

N is the original series. Series description is prefaced with ORIG.

Figure 6. Example of a Patient list with a series generated due to Save Original option selected

Phase Sensitive

N*100

Series acquired with Phase Sensitive Imaging Option are stored in the Patient List as follows:

Phase Sensitive image: N
Magnitude images: N * 100

PROPELLER

N*100 (ADC),

N*100+1 (EADC), N*100+2

Text pages

All text page images are saved into series 98 with the following numbering scheme:

1..99 Exam text pages, page 1..99 as images 1..99

101..199 Series 1 text pages, page 1..99 as images 101..199

201..299 Series 2 text pages, page 1..99 as images 201..299

Thus for series N the text pages will be saved to images numbered: N*100+page_no

T1Mapping

N*100

The number of series generated is equal to the number of scan locations. For example, series 3 has 10 slice locations, the system does not create a series 3 in the patient list, but instead creates series 300-390 with each series being 10 phases of one scan location.
