Problems solved by technology

However, MRI systems are limited by their bore size, which cannot comfortably accommodate larger than average patients and large RTP bed / table decks
Also, in some positioning / fixation situations, additional bore space (>70cm) is beneficial, but such extra space does not exist with current MR systems

Embodiment Construction

[0018] refer to figure 1 , the radiation therapy planning (RTP) system 10 is capable of performing magnetic resonance imaging and / or spectroscopy as well as a second imaging modality, eg nuclear imaging such as PET, SPECT or computed tomography (CT) imaging. The RTP system 10 includes an anatomical imaging system, in the illustrated embodiment, a large bore anatomical scanner 12 such as a magnetic resonance scanner housed within a first gantry 14 . The first patient receiving bore 16 defines a first or MR examination region 18 of the MR scanner 12 . The patient receiving bore 16 has a diameter of at least 70 cm. However, larger bore diameters, eg 85 cm, are also conceivable. Larger bore MR scanners can be achieved by increasing the clear bore of the superconducting magnet and increasing the diameter of the RF body coil and gradient coil components within the bore. The reduced efficiency of the RF body coil (for the transmit function) and gradient coil components can be comp...

Abstract

A radiation therapy planning and follow-up system(10) includes an MR scanner (12) with a first bore (16) which defines an MR imaging region (18)and a functional scanner (26), e.g., a nuclear imaging scanner, or a CT scanner with a second bore (30) which defines a nuclear or CT imaging region (36). The first and second bores (16,30) have a diameter of at least 70cm, and preferably 80-85 cm. A radiation therapy type couch (90) moves linearly through the MR imaging region (18) along an MR longitudinal axis and the nuclear or CT imaging region (36) along a nuclear or CT longitudinal axis which is aligned with the MR longitudinal axis. The couch positions a subject sequentially in the MR and nuclear or CT imaging regions (18, 36). A fusion processor combines an image representation generated from data collection in the MR imaging region (18) and an image representation generated from data collection in the nuclear or CT imaging region (36) into a composite image representation and a planning processor (112) generates a radiation therapy treatment plan according to the composite image.

Description

technical field [0001] This application relates to image-guided radiation therapy planning. It is especially suitable for use in conjunction with multimodal radiation therapy planning. Background technique [0002] Radiation therapy is a common oncology treatment technique in which a dose or series of doses of high-energy gamma (gamma) radiation, particle beams, or other radiation is delivered to a patient or a targeted area of ​​a patient's body to achieve, for example, the eradication of Effects of treatment on cancerous tissue. Planning a radiation therapy session prior to radiation treatment based on one or more planning volume images for the purpose of defining the anatomical boundaries of the tumor and surrounding tissue to determine radiation beam parameters and dose distribution . Computed tomography (CT) scanners are commonly used in radiation therapy planning (RTP) because the imaging chamber is of sufficient size to accommodate large / flat radiation treatment co...
