Description

A kind of proton radiotherapy rack with image documentation equipment

Technical field

The utility model belongs to technical field of medical equipment, more particularly to a kind of proton radiotherapy machine with image documentation equipment Frame.

Background technique

In proton radiation therapy field, the image acquisition process and therapeutic process of current patient are to be individually positioned in two not It is completed in same equipment.When Image Acquisition, patient is lain on the hospital bed of image documentation equipment, acquires image on image documentation equipment later (this image documentation equipment is mainly CT), doctor formulates treatment plan after analyzing acquired image, while obtaining patient's lesion The data such as location information.Later, patient is placed on the ward bed of radiotherapy apparatus by radiotherapy, radiotherapy apparatus shadow before The information divergent-ray such as lesions position obtained as equipment is treated.And in the above process, patient is acquiring image data Afterwards, on the hospital bed for needing to be moved to another treatment, in the process, position of the patient on two hospital beds will appear partially Difference, it is contemplated that lesion in patient body can change position with the different gestures of patient, therefore patient puts deviation and the patient of position When the variation of posture will lead to radiotherapy, ray can not accurately be got in lesion, influence therapeutic effect.

Summary of the invention

The utility model aim is that in view of the drawbacks of the prior art, providing a kind of can allow patient complete on same hospital bed At image acquisition process and therapeutic process, guarantees that patient set-up deviation will not occur during two differences, treatment is allowed to penetrate Line is more accurate to be got in lesion, and the proton radiotherapy rack with image documentation equipment of the effect of radiotherapy is improved.

The utility model to achieve the above object, adopts the following technical scheme that

A kind of proton radiotherapy rack with image documentation equipment, the rotary frame including proton radiotherapy apparatus, it is characterised in that: its It further include therapeutic bed and image documentation equipment；The therapeutic bed is located in the image documentation equipment, and the image documentation equipment is located at the rotation Rack inner ring；Between the therapeutic bed and image documentation equipment, between the therapeutic bed and rotary frame, the image documentation equipment and rotation Relative displacement is driven by driving device between rack.

It is further characterized by: the axis of the therapeutic bed, image documentation equipment and rotary frame is parallel to each other.

Preferred: the image documentation equipment is spiral CT or MRI.

It is further further characterized in that: the image documentation equipment is fixed on the bottom plate of top, and the therapeutic bed is fixed at On sliding block；The top bottom plate and sliding block are movably arranged on lower raft, can be relatively moved on the lower raft；It is described Lower raft is fixedly connected with rotary frame.

Further: the top bottom plate is connected by two side rails with the lower raft；During the sliding block passes through Between guide rail be connected with the lower raft.

There are hollow slots, the sliding block can move in the hollow slots on the top bottom plate.

The equal centers of the isocenter point of the X-ray of the spiral CT and the treatment beam of proton radiotherapy apparatus outgoing Point is overlapped.

The utility model has the following beneficial effects:

1. solving the problems, such as to be needed when patient carries out Image Acquisition and radiotherapy in two different hospital bed operations.Tradition Radiotherapy carrying out Image Acquisition and when radiotherapy, patient needed to complete on two different hospital beds.This is practical new Type completes the above process on a hospital bed.

2. solving the problems, such as that pendulum position is inconsistent when patient carries out Image Acquisition and radiotherapy.Traditional radiotherapy Image collection process and radiation therapy process need patient to complete on two hospital beds respectively, so need patient sick up and down twice Bed causes patient to be difficult the one straightforward of holding position and posture on two hospital beds, and the utility model makes the above process at one It is completed on hospital bed, solves the problems, such as that pendulum position is inconsistent.

Lesions position is inconsistent when the lesions position and actual therapeutic that find when 3. solving the problems, such as Image Acquisition.Tradition Radiation therapy process will lead to patient and repeatedly put position, and Set-up errors can all be had by being put between position every time, while patient's posture is also difficult It is consistent, causes actual focal position and actual therapeutic position inconsistent.The utility model can make above-mentioned lesions position It is consistent with treatment position.

4. solving the problems, such as that treatment region is excessive relative to lesion volume when radiotherapy.(traditional radiation therapy in order to Lesion can be sufficiently treated, the volume for the treatment of region is increased.) due to conventional radiotheraphy during, the lesions position and reality of patient There is deviation in border treatment position, and in order to guarantee therapeutic effect, the volume for the treatment of region can be bigger than actual lesion volume, so then Result in the damage of excessive normal tissue.The utility model reduces above-mentioned deviation, thus reduce in therapeutic process it is excessive just The damage often organized.

Specific embodiment

As shown in Figure 1-3, a kind of proton radiotherapy rack with image documentation equipment, the rotary frame 1 including proton radiotherapy apparatus, Therapeutic bed 2 and image documentation equipment 3.Therapeutic bed 2 is located in image documentation equipment 3, and image documentation equipment 3 is located at 1 inner ring of rotary frame.Therapeutic bed 2, The axis of image documentation equipment 3 and rotary frame 1 is parallel to each other.Lower raft 4 is fixedly connected on rotary frame 1.Image documentation equipment 3 is solid It is scheduled on top bottom plate 5, therapeutic bed 2 is fixed on sliding block 6.Top bottom plate 5 passes through two side rails 7 and 4 phase of lower raft Connection；Sliding block 6 is connected by intermediate rail 8 with lower raft 4.There are hollow slots, sliding block 6 can be in hollow out on top bottom plate 5 It is moved in slot.Between therapeutic bed 2 and image documentation equipment 3, between therapeutic bed 2 and rotary frame 1, image documentation equipment 3 and rotary frame 1 it Between relative displacement driven by driving device.

Preferred: image documentation equipment 3 is spiral CT.Isocenter point and proton the radiotherapy apparatus outgoing of the X-ray of spiral CT The isocenter point for treating beam is overlapped.Image documentation equipment 3 is also possible to MRI nuclear magnetic resonance equipment.

When utility model works, patient 9 is lain in therapeutic bed 2, and sliding block 6 moves on lower raft 4 along intermediate rail 8 It is dynamic, so that therapeutic bed 2 is moved to the treatment region of radiotherapy.Upper back bottom plate 5 on lower raft 4 along two side rails 7 move It is dynamic, the image documentation equipment 3(spiral CT on top bottom plate 5) data of acquisition patient are moved forward and backward on lower raft 4.Data at this time It is acted on of both having, on the one hand this data is the treatment data for the treatment of plan, and on the other hand this data is the accurate position of lesion Set data.Radiotherapy apparatus issues ray and treats to patient later.
