Proton Therapy Center in Prague Becomes First Czech Clinic to Order RayStation

STOCKHOLM, May 17, 2019 -- (Healthcare Sales &Marketing Network) -- Proton Therapy Center Czech (Prague PTC) is the only one of its kind in Czechia, and it has selected RayStation® as its sole treatment planning system. This is RaySearch's first orde... Devices, Oncology RaySearch Laboratories, RayStation, treatment planning, proton therapy

ConclusionsVMAT is now widely available, and high-quality VMAT plans that incorporate cardiac substructures into the optimization process can provide overall improvements in dose to OARs and, in particular, substantial sparing of critical cardiac structures. IMPT provides some incremental dosimetric improvements beyond cardiac-optimized VMAT, the clinical significance of which remains uncertain.

ConclusionRITI can be induced in patients with NSCLC through upregulated IgG and/or IgM. RITI response was not associated with proton versus photon therapy or with clinical outcomes in this small cohort and should be examined in a larger cohort in future studies.

This study aimed at directly comparing the RSP accuracy of both modalities using phantoms scanned at an advanced prototype pCT scanner and a state-of-the-art DECT scanner.
 Two phantoms containing 13 tissue-mimicking inserts of known RSP were scanned at the pCT phase II prototype and a latest generation dual-source DECT scanner (Siemens SOMATOM Definition FORCE). RSP accuracy was compared by mean absolute percent error (MAPE) over all inserts. A highly realistic Monte Carlo (MC) simulation was used to gain insight on pCT image artifacts which degraded MAPE.
 MAPE was 0.55% for pCT and 0....

f J Abstract Some clinical indications require small fields with sharp lateral dose gradients, which is technically challenging in proton beam therapy. This holds especially true for low-range fields applied with the spot scanning technique, where large beam profiles entering from the beam-line or the insertion of range shifting blocks lead to large lateral gradients. We regard the latter case and solve it by shifting the range shifting block far upstream in conjunction with a collimating aperture close to the patient. The experiments of the current work are based on a commercial proton therapy treatment head desi...

At the conclusion of a recent office visit, one of our patients summarized his feelings and stated, with a sense of absolute conviction, “The only type of radiation therapy I am willing to undergo is proton therapy.” In contrast, another recent patient facing a similar situation stated, “I don't care which I get [proton or photon therapy]; to me, it sounds like it's the team, not the beam.” The former patient put his hope in a technology; the latter patient prioritized the experience of his care team over any particular technology.

CONCLUSIONS: IMPT following IBR spared underlying organs and had low rates of acute toxicity. Reconstruction complications are more common in irradiated breasts, and reconstructive outcomes appear comparable with photon literature. Hypofractionation was associated with higher reconstruction failure rates. Further investigation of optimal dose-fractionation after IBR is needed. PMID: 31185327 [PubMed - as supplied by publisher]

Proton Computed Tomography (proton CT) is an imaging modality able to measure the proton stopping power of the patient prior to treatment planning and treatment in proton therapy [1]. The goal of proton CT is to increase the accuracy of the proton range estimation, compared to conversion from the X-ray mass attenuation using X-ray CT [2]. Several design approaches for proton CT have been proposed. Usually, tracker planes in front of and behind the patient measure each proton ’s position and direction so that their path through the patient can be estimated [3,4].
