(1.33±0.49)mm；
Understand: self-control angle adjustable razor-edge liner and negative-pressure vacuum pad are respectively cooperating with thermoplastic head-neck-shoulder mould position
Technique for fixing is in bow-backed tumor of head and neck Patients Treated by Radiotherapy pendulum position, and Set-up errors and coordinate system Transfer Error all ratios are general
Logical soft pillow is low, reproducible, and equal accurate between the two.
3 operation principles:
In 3.1 Patients During Radiotherapies, patient's fixation postures is one of key factor affecting radiotherapy precision.Determining trouble
When person treats position, patient to be allowed first according to the requirement for the treatment of technology to obtain one by treatment body position fixture
Individual relatively comfortable, reproducible position.Thermoplastic head-neck-shoulder mould Postural immobilization technology is to general head and neck region tumors
Patient has preferable Postural immobilization, higher radiotherapy position repeatability, but to bow-backed head and neck position tumor patient effect
The rarest research of fruit.The author finds that this some patients is by body position fixture such as vacuum pad, soft bolster height waist buttocks
Portion lies on the back when the treatment technology that head rest, thermoplastic head-neck-shoulder mould are fixed requires with satisfied head, by the pendulum of vacuum pad
Position repeatability is better than soft pillow, but the moulding time-consuming length of the former evacuation, follow-up use need special messenger's special counter put；Often
It to check, gas leakage deformation need to process in time；The vacuum bag of half soft state, must make and again to simulator locating
Under machine, perspective resets, and can supply Clinical practice.Use process is loaded down with trivial details time-consuming, relatively costly.Can find and save time
Economical, the alternative method of Simple durable, has done further research for this.
In accurate radiotherapy, CT-sim fixed (school) position, TPS make a plan, describe tumor center locus,
Treatment pendulum position, coordinate system transfer etc. every time, all to be pasted onto on thermoplastic neck shoulder (body) film on the plane of reference of location
Three metal markers the same coordinate system i.e. coordinate origins of being formed on the basis of carry out.But actually coordinate system
Initial point is because of the expansion performance of thermoplastic neck shoulder (body) film, and self there is also Set-up errors.Therefore from tightened up meaning
Say and for basis reference research and position repeatability and tumor center's Set-up errors should not be described with it.Using taper
Bundle CT (cone-beam CT, CBCT) carries out finding during the research of tumor of head and neck Set-up errors, with use gold point
Comparing Deng knub position label, bony structure is substantially not present deformation problems, and acquired results should have higher
Reliability.Patient coordinate system can be determined by visible bony structure in the images such as CT.The position of bone labelling leads to
Often the current check when treatment starts, generally verifies weekly once in the most whole therapeutic process.The cerebral tumor and upper
The target area of cervical region pathological changes keeps a fixed position to be possible relative to local bony structure.
Human body left and right belemnoid point foot direction last layer central point, fixes in the position of incidence, is chosen as head and neck
Portion's bone labelling reference point.Two somes relative tertiary location in coordinate system changes, then mark patient's incidence
The change of position, points out Set-up errors.Plane of reference coordinate origin and center, right the last layer of direction of belemnoid point foot
Point spatial position change in coordinate system, then point out coordinate system Transfer Error.By CT image and system
Software, above-mentioned error all can record.
Preferably the Set-up errors of tumor of head and neck radiotherapy is below 2mm.Research finds, makes adjustable angle by oneself
Degree razor-edge liner and negative-pressure vacuum pad are respectively cooperating with thermoplastic head-neck-shoulder mould Postural immobilization technology and swell in bow-backed incidence
In tumor Patients Treated by Radiotherapy pendulum position, both no matter Set-up errors or coordinate system Transfer Error all in the range of 2mm.
Common soft pillow Set-up errors and coordinate system Transfer Error are the most repeatedly more than 2mm.Result of study shows the above two
Set with intracranial reducing error and fixed (pendulum) position coordinate origin between two intrinsic bone labellings that intracranial sets
Certain intrinsic bone labelling between two equal not statistically significants of aspect (P > 0.05) of Set-up errors, i.e. equal accurately,
Reproducible；But the moulding time-consuming length of the latter's evacuation, cost are high, have gas leakage to unmake risk, the former then saves time province
Money, Simple durable, therefore bow-backed tumor of head and neck Patients Treated by Radiotherapy pendulum position makes angle adjustable razor-edge liner by oneself and completely may be used
To substitute vacuum pad.
3.2 trace it to its cause: owing to there is certain interval between thermoplastic head-neck-shoulder mould and headrest (torr), human body in addition
The free mobility of cervical vertebra is relatively big, thus every time pendulum position time cervical vertebra degree of crook, there is some difference in direction, bow-backed
Patient is more so: for meeting dorsal position, the treatment technology in head rest, thermoplastic head-neck-shoulder mould fixing head cervical region of resting the head on is wanted
Ask, when by back cushion padded waist buttocks, too high: incidence toward entering, move, Qu Chengdu adds after cervical vertebra by a direction
Greatly, lower jaw is raised；Too low: incidence moves toward going out a direction, receives in bent, lower jaw before cervical vertebra.Make by oneself adjustable
Angle wedge-shaped backing plate by record, labelling the right and left and (relative to patient, fixed mount) scale of centre,
Mark line and the wedge angle of razor-edge liner, therefore during the treatment of patient per's repeated positioning, under laser rays guides
Can accurately be placed in waist buttocks same position as negative-pressure vacuum pad, make waist hip pad high level consistent,
Reduce when patient per puts because of waist buttocks back cushion putting position, padded degree is inconsistent and the head and neck position drawn
Put change, reduce Set-up errors and coordinate system Transfer Error.And use common soft bolster height waist buttocks to weigh every time
During the treatment of physical pendulum position, not fixing because soft pillow is placed in the position of waist buttocks, stress is different, causes waist buttocks padded
Degree differ, and soft pillow is repeatedly used for a long self compression, thus the change of drawing head neck location, increases
Set-up errors and coordinate system Transfer Error.
Certainly, research is also doped with the Set-up errors that the factors such as body weight change during Patients Treated by Radiotherapy produce, but
The probability two groups of patients being produced error in view of above-mentioned factor is identical, therefore little on research conclusion impact.
To sum up, self-control angle adjustable razor-edge liner is reproducible in bow-backed tumor patient radiotherapy position, head and neck position
Save time again economical, Simple durable, clinic popularization and application.
