Radiographic imaging system

Номер: US20120001082A1

Автор: Kazuo Hashiguchi, Makoto Shoho

Принадлежит: Sharp Corp

A response with a wider dynamic range is obtained without a need for irradiating strong radiation onto a subject (human body). A CCD controller 22 allows reading of imaging signals from CCD image sensors 1 to 12, which is performed twice during different time periods, once during a long exposure time period and once during a short exposure time period, with respect to the irradiation of a constant dose of radiation by an X-ray generator 25; and a main controller 26 allows a memory 24 to synthesize image data from the successively twice-read imaging signals into an image with proper timing. As a result, it becomes unnecessary to irradiate strong radiation onto a subject, such as a human body and other substances, as is done conventionally, owing to a radiation dose weak enough not to cause a harmful influence.

Imaging mode blooming suppression

Номер: US20120002012A1

Автор: Brian D. Hoffman, Ian McDowall, Patrick O'grady

Принадлежит: Intuitive Surgical Operations Inc

A minimally invasive surgical includes a scene anti-bloom process that allows switching between imaging modes on a stereoscopic display without causing a surgeon to look-away or being momentarily distracted by sudden changes in overall scene luminance. The process receives a switch from a first imaging mode to a second imaging mode. An overall scene luminance of a scene in the first imaging mode is less than an overall scene luminance of a scene in the second imaging mode. The process delays the switch to the second imaging mode until after an illumination output level of a visible illumination source has changed to a higher output level, and then switches to the second imaging mode.

Hybrid dual-modality image processing system and method

Номер: US20120002857A1

Автор: Alicia Wong, Angela Da Silva, Jinghan Ye, Jingkun Hu, Sudhir K. Mahakali, Xiyun Song

Принадлежит: KONINKLIJKE PHILIPS ELECTRONICS NV

Hybrid dual-modality image processing systems and methods are disclosed. For example, an image processing system includes a computer for processing SPECT tomographic projection data and a CT volume image. The computer derives a SPECT transverse volume image from the projection data and registers the SPECT transverse volume image with the CT volume image to obtain an attenuation map and registration information. The computer uses the attenuation map and the registration information to derive a SPECT transverse volume image with attenuation correction. The computer uses the registration information to derive a SPECT transverse volume image without attenuation correction. The SPECT transverse volume images, with and without attenuation correction, are derived at or near the same time, using the same registration information. The registration information is stored in, carried by, or otherwise communicated through the attenuation map for subsequent processing of the SPECT transverse volume images.

Полезная модель относится к области медицины, а точнее, к техническим средствам (медицинская техника), предназначенным для обнаружения, диагностики и лечения опухолей в маммологии путем применения различных видов излучений, в том числе и ультразвукового. Сущность полезной модели заключается в том, что устройство для фиксации молочной железы при неинвазивном способе её исследования и/или лечения включает компрессионный блок, содержащий пару параллельно расположенных друг над другом прямоугольных пластин, верхняя из которых установлена подвижно относительно нижней пластины, в свою очередь, смонтированной на платформе, установленной с возможностью вертикального перемещения на стойке, которая закреплена на основании. Каждая из пары боковых сторон верхней пластины связана с соответствующими сторонами нижней пластины посредством пары ломающихся рычагов, концы которых шарнирно соединены со сторонами пластин, а собственно шарнир каждого ломающегося рычага снабжен зажимом, обеспечивающим, при необходимости, неподвижность его рычагов относительно друг друга, при этом нижняя пластина имеет разъёмную связь с платформой, а стойка выполнена в виде силового цилиндра, закреплённого на основании, и представляющего собой электроцилиндр. Технический результат полезной модели состоит в устранении механического привода перемещения верхней пластины в компрессионном блоке и трансформации последнего в малогабаритную конструкцию с ручным приводом. В результате устройство для фиксации молочной железы легко подстраивается под сидящую на стуле пациентку, что делает проводимые процедуры более комфортными. Кроме того, пространство над устройством дает больше возможностей при манипулировании активной частью прибора HIFU.

Заявляемая полезная модель относится к области медицинской техники, а именно к средствам контроля параметров качества полученных на компьютерном томографе изображений, позволяющим оценить эффективность алгоритмов и методов подавления артефактов от металлоконструкций. Наиболее близким к заявленному техническому решению является фантом фирмы Gammex (Ballhausen et al. Post-processing sets of tilted CT volumes as method for metal artifact reduction. Radiation Oncology. 2014; 9:114-124; PCT/US 2017/063083. Automated detection and identification of phantoms) с измененной конфигурацией для исследования алгоритмов подавления артефактов от металла. Данный фантом представляет собой диск, заполненный твердым материалом - эквивалентом воды. По объему фантома расположены ячейки, которые заполняются веществами с разными рентгеновскими плотностями, а в одну из ячеек помещают вставку из титана. Недостатками указанного прототипа является наличие в фантоме твердого материала - эквивалента воды, который невозможно заменить на образцы, имитирующие другие ткани. Кроме того, конструкцией не предусмотрена имитация жировой ткани. Техническая задача, решаемая заявляемой полезной моделью, состоит в оценке эффективности применения различных алгоритмов снижения уровня артефактов от металлоконструкций при возможности моделировании различных параметров тела пациента. Решение поставленной технической задачи обеспечивается рядом отличительных существенных признаков, а именно наличием емкостей с контрольными веществами разной рентгеновской плотности (в диапазоне, соответствующем диапазону рентгеновских плотностей тканей человека), с возможностью замены вещества, заполняющего внутренний объем фантома.

However, a number of normally functioning organs uptake high amounts of imaging tracer, particularly FDG. Therefore, a suppression unit ( 102 ) suppresses regions of high tracer uptake in the functional second image representation based on the results of a classification unit ( 101 ). The classification unit classifies the regions of high tracer uptake according to their position relative to the anatomical structures segmented from the anatomical first image representation. The remaining un-suppressed regions of high uptake are identified by an identification unit ( 106 ) as one of potential lesion and non-potential lesion.
