TREATMENT DEVICE FOR DELIVERING A TREATMENT PLAN FOR FLASH DEPOSITION WITH AN ACCELERATOR OF CHARGED PARTICLES BY PENCIL BEAM SCANNING
A treatment device includes a pulsed particles accelerator and a processor for controlling the latter to deliver a treatment plan by deposition at HDR of charged particles into a flash volume (Vht) by PBS. To shorten the time for depositing a target dose (Dti) into the cells spanned by the flash spots (Si) of the flash volume (Vht), the flash spots are combined into k sets of n flash spots (Si). After depositing a j.sup.th pulse dose (Dij) into the cells spanned by a i.sup.th flash spot (Si) the beam commutes from the ith flash spot (Si) to a next (i+1)th flash spot according to a flash scanning subsequence to deposit a jth dose into the cells spanned by each of the subsequent flash spots of the flash scanning subsequence, until returning to the ith flash spot to deposit a (j+1)th dose (Di(j+1)), and so on When all the cells spanned by all the flash spots of a set have received their corresponding target dose, the beam moves to a next set of combined flash spots and repeats the foregoing pulse deposition steps.

Patient weight estimation from surface data using a patient model
For patient weight estimation in a medical imaging system, a patient model, such as a mesh, is fit to a depth image. One or more feature values are extracted from the fit patient model, reducing the noise and clutter in the values. The weight estimation is regressed from the extracted features.
PLANNING RADIATION THERAPY USING A PERSONALIZED HEMATOLOGIC RISK SCORE
Thereto a method and a system for planning radiation therapy are provided, as well as an arrangement for radiation therapy planning and a computer program product for carrying out the method. For planning the radiation therapy, the following steps are performed. Patient data of a subject to be treated is received as well as image data of the subject to be treated.
